General

Which coating do I need?

There is an ideal coating for every situation. To make the right choice, it’s first important to establish which part of the light spectrum requires adjustment and in which season this is necessary. We’ve developed a tool called the ReduWizard to calculate the best solution for your situation based on your crop, location and climate. The ReduWizard combines weather data from local weather stations all over the world with each crop’s climate requirements for optimal production. Simply enter your location, crop and greenhouse details to receive customized advice. Go to the ReduWizard here

How much shading does my crop need?

Every crop reacts differently to light and climate. Light-loving crops such as roses, tomatoes, peppers and cucumbers need a lot of light but also need protection from radiation peaks. Other crops love shade, such as many potted plants and orchids, in which case a high amount of shading is needed. Read more about how much light your crop needs here. For the best advice, contact your crop consultant or a ReduSystems account manager in your region.  

Can all products be applied by hand?

We always recommend applying our products mechanically for the best results. However, most of our products can also be applied manually. The exception is AntiReflect, which can only be applied using a machine fitted with a spraying computer. 

Can I use ReduSystems products safely on diffuse glass with a factory AR coating?

ReduSystems products have been specifically developed for the horticultural sector and, providing they are used as prescribed, will not damage standard greenhouse glass. For specially treated greenhouse materials (e.g. diffuse glass, AR treatments), however, we advise you to contact the glass supplier first and/or test the product on a small area of your glass. ReduClean is safe for use with our own antireflection coating (AntiReflect) since our products are specially designed to be combined. 

How should I apply the coatings if I do not have a spraying machine?

For the best results, a coating must be applied to the greenhouse cover as evenly as possible, because an uneven layer may cause growth differences in the crop. It is possible to apply the coatings by hand, by machine, by airplane or helicopter.

A machine gives the most even layer as the equipment can be precisely adjusted to the type of product. It also minimizes the loss of product caused by excessive spraying.

Most of our products (except AntiReflect) can also be applied manually using a spray gun. The overall result depends on the quality and functionality of the spray gun, such as the flow speed, dilution of the shading material and the experience of the applier. More information about manual spraying can be found here.

Application by airplane or helicopter is also an option (except for AntiReflect and GS-4) and is especially suitable in the case of large greenhouses. However, the pilot must have the necessary know-how and experience, and the equipment must be of high quality and well maintained.

Should I apply the product just once or can I apply multiple layers?

Our transmission, reflection and cleaning products should be applied just once each time. In the case of our shading, diffusion and specialty coatings, both options are possible. In fact, a multi-layer approach offers several advantages over a single layer. After all, some plants can suffer stress when they are suddenly being shaded. Applying the coating gradually in several layers gives the plant more time to adjust. In addition, if a single layer is applied too thickly, it may not stick to the roof properly. Therefore, multi-layer application can be an interesting alternative in some situations. 

Can I apply layers of different products on top of each other?

Yes, it is possible to apply layers of different ReduSystems products on top of each other. For example, ReduSol applied on top of ReduHeat will increase the shading effect in the summer. 

What’s the difference between a liquid coating and powder products?

ReduSystems coatings are liquid and therefore easier to use than powder products; no vigorous mixing is needed. Also, the applied layer is more homogeneous, and the ReduSystems coatings are removable. 

Why should I use a coating if I already have screens?

A coating is more effective in keeping excessive light and heat out of greenhouses than movable screens. For example, some of the energy that accumulates above closed screens will still spread into the greenhouse. Additionally, when the screens are fully closed the greenhouse can quickly become too hot, but partially opening the screens to release the heat will expose some of your plants to the sun. When used together, the coating provides the basic protection and the screens act as an ‘emergency brake’ in the case of extremes. Read more about this topic here.

Where can I buy your products?

We have a large network of distributors around the world. We work closely with our local distributors to offer our products and specialized solutions for each specific crop. You can find an overview of our distributors on this page. It is not possible to purchase products directly from Lumiforte. 

How long can the products be stored?

The maximum shelf life differs per product. For specific details, please check the product packaging or the product pages on our website. Products should always be stored in their original packaging in a cool, well-ventilated place. Products should be protected against frost (above 5 ⁰C) and overheating (below 35 ⁰C).

  • ReduSol: unopened containers have a shelf life of two years.
  • ReduHeat, ReduFuse, ReduFuse IR, ReduFlex Blue, SprayChalk: unopened containers have a shelf life of two years. After one year, it is necessary to stir well in the bucket before mixing with water.
  • AntiCondens: unopened containers have a shelf life of one year.
  • AntiReflect: when stored at a temperature above 5 ⁰C, shelf life is four weeks after receipt.
  • PipePaint: unopened containers have a shelf life of two years. Always stir before use.
  • All ReduClean versions: unopened containers have a shelf life of three years.
  • GS-4 (Xtra): unopened containers have a shelf life of three years.
Which ReduSystems products can be safely used on plastic?

Almost all ReduSystems products are suitable for use on plastic. The exceptions are AntiReflect and GS-4 (Xtra), which are only suitable for use on glass.
ReduFuse is safe to use on plastic greenhouses without any damage, but it is more suitable for use on glass. Many types of plastic already diffuse the light to some extent. In addition, the removal of ReduFuse should be done with a brushing machine to ensure proper removal. A better alternative is ReduFuse IR, which diffuses the light and keeps out some of the heat. ReduFuse IR can be removed without a brushing machine.

ReduSol

When should I use ReduSol and when should I use ReduHeat?

Each shading agent has its own features, so the most suitable solution for your situation depends mainly on the crop, the location of the greenhouse and the climate. ReduSol provides a similar amount of shading across the whole energy spectrum, shading both light and heat from the sun. However, ReduHeat is a better choice if your crop suffers from heat more than light. The ReduHeat coating shades the plants from infrared light, which generates heat, while still letting through light to support plant growth. If you are looking for maximum shading of heat and light, ReduSol is the best option.

How do I apply ReduSol?

The best and longest-lasting results are obtained when the coating is applied to a clean, dry greenhouse roof, as follows:

  1. Fill the mixing tank with the required quantity of clean water and add ReduSol, stirring continuously.
  2. Stir the spray liquid frequently during application.
  3. Apply ReduSol evenly to the greenhouse surface, preferably using a spraying machine.
  4. Never use any non-ReduSystems shading products in combination with ReduSol.

The ideal weather conditions for applying ReduSol

  • An outside temperature between 5 and 30 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended, plus the spray could blow onto nearby objects such as cars and buildings.
  • For fast drying: relative humidity (RH) < 80 %. The exact drying time also depends on other conditions (such as amount of applied ReduSol, outside temperature, glass temperature and wind speed). The coating should be dry before nightfall because condensation may damage the layer.
  • Do not apply ReduSol to a wet surface or during rainfall because this may create an uneven layer of coating on the glass.
  • Do not apply when rain is expected within six hours, since the coating is highly likely to be damaged or to be washed away completely.
Can the rainwater that runs off a roof coated with ReduSol be reused as irrigation water (in soil or substrate) without phytotoxicity?

Growers have been using ReduSol for over 30 years, during which they have been collecting rainwater for reuse with their crops. There have been no problems regarding phytotoxicity. However, every situation is unique; the crop, location, size of the irrigation basin and timing of the application of ReduSol can differ. To be 100% sure of the quality of your irrigation water, we advise you to analyze it for the presence of ReduSol by checking that the calcium level and pH are within the normal range.   

Why does the water turn white after using ReduClean?

Our removable shading product ReduSol is based on chalk, which is an environmentally harmless mineral. When ReduClean is used, the coating dissolves and the chalk residue causes white discoloration in the water. To avoid this, you can take the precautionary measures as described on the product packaging. 

Can I allow wastewater containing ReduSol and ReduClean to flow back into my irrigation basin?

We advise you to check the usability of the water in the irrigation basin after any inflow of ReduSol and/or ReduClean. Check whether the water is cloudy (which can indicate the presence of calcium carbonate) and measure the pH value to determine whether the water can be used for irrigation purposes. If you plan to acidify the water before use, the combination of the acid with calcium carbonate could form bicarbonate, which can be harmful to certain crops such as roses. In this case, you should wait until the chalk has sunk to the bottom of the basin before using the water for irrigation purposes. We advise you to monitor the pH level of the water and make the necessary adjustments prior to use, or to close the reservoir inlet during removal of a coating.

ReduHeat

When should I use ReduSol and when should I use ReduHeat?

Each shading agent has its own features, so the most suitable solution for your situation depends mainly on the crop, the location of the greenhouse and the climate. ReduSol provides a similar amount of shading across the whole energy spectrum, shading both light and heat from the sun. However, ReduHeat is a better choice if your crop suffers from heat more than light. The ReduHeat coating shades the plants from infrared light, which generates heat, while still letting through light to support plant growth. If you are looking for maximum shading of heat and light, ReduSol is the best option.

What’s the difference between ReduHeat and ReduFuse IR?

Both coatings reflect a part of the (near) infrared light while transmitting a large amount of PAR light. The differences between ReduHeat and ReduFuse IR are in the degree of diffusion (Hortiscatter) and the amount of infrared reflection. The diffusion (Hortiscatter) of ReduFuse IR is higher compared with the same amount of ReduHeat. If the same amount of buckets/ha are used, ReduHeat will reflect more infrared light which causes the greenhouse to heat. Due to ReduHeat’s higher capacity to reflect infrared light, the plant will respond more generatively compared to ReduFuse IR despite having a lower leaf temperature. In contrast, ReduFuse IR causes a greater scattering of light (diffusion) which stimulates more vegetative growth. Read more about the differences between ReduHeat and ReduFuse IR in this article

How do I apply ReduHeat?

The best and longest-lasting results, with optimum light transmission, are obtained when ReduHeat is applied to a clean greenhouse roof, as follows:

  1. Fill the mixing tank with the required quantity of clean water and add ReduHeat, stirring continuously.
  2. Stir the spray liquid frequently during application.
  3. Apply ReduHeat evenly to the greenhouse surface, preferably using a spraying machine.
  4. Never use any non-ReduSystems shading products in combination with ReduHeat.

The ideal weather conditions for applying ReduHeat

  • An outside temperature between 10 and 25 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended, plus the spray could blow onto nearby objects such as cars and buildings.
  • For fast drying: relative humidity (RH) < 80 %. The exact drying time also depends on other conditions (such as amount of applied ReduHeat, outside temperature, glass temperature and wind speed). The coating should be dry before nightfall because condensation may damage the layer.
  • Do not apply ReduHeat to a wet surface or during rainfall because this may create an uneven layer of coating on the glass.
  • Do not apply when rain is expected within 12 hours, since the coating is highly likely to be damaged or to be washed away completely. 

SprayChalk

How do I apply SprayChalk?

The best and longest-lasting results are obtained when the coating is applied to a dry greenhouse roof, as follows:

  1. Fill the mixing tank with the required quantity of clean water and add SprayChalk, stirring continuously.
  2. Stir the spray liquid frequently liquid during application.
  3. Apply SprayChalk evenly to the greenhouse surface, preferably using a spraying machine.
  4. Never use any non-ReduSystems shading products in combination with SprayChalk.

The ideal weather conditions for applying SprayChalk

  • An outside temperature between 5 and 40 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended, plus the spray could blow onto nearby objects such as cars and buildings.
  • For fast drying: relative humidity (RH) < 80 %. The exact drying time also depends on other conditions (such as amount of applied SprayChalk, outside temperature, glass temperature and wind speed). The coating should be dry before nightfall because condensation may damage the layer.
  • Do not apply SprayChalk to a wet surface because this may create an uneven layer of coating on the glass.
  • Do not apply SprayChalk in the rain. This coating is developed for temporary use or as a second layer. A few rain showers will wash the coating off the greenhouse roof.
How can SprayChalk be removed?

SprayChalk will gradually wash off the greenhouse by a few rain showers.

ReduFuse

How do I apply ReduFuse?

The best and longest-lasting result, with optimum light transmission, are obtained when ReduFuse is applied to a clean greenhouse roof, as follows:

  1. Fill the mixing tank with the required quantity of clean water and add ReduFuse, stirring continuously.
  2. Stir the spray liquid frequently during application.
  3. Apply ReduFuse evenly to the greenhouse surface, preferably using a spraying machine.
  4. Never use any non-ReduSystems shading products in combination with ReduFuse.

The ideal weather conditions for applying ReduFuse

  • An outside temperature between 10 and 25 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended, plus the spray could blow onto nearby objects such as cars and buildings.
  • For fast drying: relative humidity (RH) < 80 %. The exact drying time also depends on other conditions (such as amount of applied ReduFuse, outside temperature, glass temperature and wind speed). The coating should be dry before nightfall because condensation may damage the layer.
  • Do not apply ReduFuse to a wet surface or during rainfall because this may create an uneven layer of coating on the glass.
  • Do not apply when rain is expected within 12 hours, since the coating is highly likely to be damaged or to be washed away completely.
Can I use ReduFuse on plastic?

Yes, but be aware that the removal of ReduFuse should be done with a brushing machine to ensure proper removal. Many types of plastic already diffuse the light to some extent. You could use a diffuse coating like ReduFuse to achieve extra diffusion but that is often unnecessary. ReduFuse IR, on the other hand, keeps out some of the heat too, which can make it a good addition for plastic greenhouses in the case of certain crops.

ReduFuse IR

What’s the difference between ReduHeat and ReduFuse IR?

Both coatings reflect a part of the (near) infrared light while transmitting a large amount of PAR light. The differences between ReduHeat and ReduFuse IR are in the degree of diffusion (Hortiscatter) and the amount of infrared reflection. The diffusion (Hortiscatter) of ReduFuse IR is higher compared with the same amount of ReduHeat.

In contrast, ReduFuse IR causes a greater scattering of light (diffusion) which stimulates more vegetative growth. Read more about the differences between ReduHeat and ReduFuse IR in this article

Can I use ReduFuse IR on plastic?

Yes, ReduFuse IR can be used on plastic. Many types of plastic already diffuse the light to some extent, so extra diffusion is often not necessary. However, ReduFuse IR reflects part of the heat too so it can be a worthwhile addition for plastic greenhouses. 

How do I apply ReduFuse IR?

The best and longest-lasting results, with optimum light transmission, are obtained when ReduFuse IR is applied to a clean greenhouse roof, as follows:

  1. Fill the mixing tank with the required quantity of clean water and add ReduFuse IR, stirring continuously.
  2. Stir the spray liquid frequently during application.
  3. Apply ReduFuse IR evenly to the greenhouse surface, preferably using a spraying machine.
  4. Never use any non-ReduSystems shading products in combination with ReduFuse IR.

  • An outside temperature between 10 and 25 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended, plus the spray could blow onto nearby objects such as cars and buildings.
  • For fast drying: relative humidity (RH) < 80 %. The exact drying time also depends on other conditions (such as amount of applied ReduFuse IR, outside temperature, glass temperature and wind speed). The coating should be dry before nightfall because condensation may damage the layer.
  • Do not apply ReduFuse IR to a wet surface or during rainfall because this may create an uneven layer of coating on the glass.
  • Do not apply when rain is expected within 12 hours since the coating is highly likely to be damaged or to be washed away completely.

ReduFlex Blue

What is the effect of ReduFlex Blue?

ReduFlex Blue partially reflects blue light, so the ratio between the colors in the light spectrum are changed. This can increase the stem length in certain crops, which can be particularly desirable in cut flowers such as roses. Read more about ReduFlex Blue here.  

How do I apply ReduFlex Blue?

The best and longest-lasting results, with optimum light transmission, are obtained when ReduFlex Blue is applied to a clean greenhouse roof, as follows:

  1. Fill the mixing tank with the required quantity of clean water and add ReduFlex Blue, stirring continuously.
  2. Stir the spray liquid frequently during application.
  3. Apply ReduFlex Blue evenly to the greenhouse surface, preferably using a spraying machine.
  4. Never use any non-ReduSystems shading products in combination with ReduFlex Blue.

The ideal weather conditions for applying ReduFlex Blue

  • An outside temperature between 10 and 25 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended, plus the spray could blow onto nearby objects such as cars and buildings.
  • For fast drying: relative humidity (RH) < 80 %. The exact drying time also depends on other conditions (such as amount of applied ReduFlex Blue, outside temperature, glass temperature and wind speed). The coating should be dry before nightfall because condensation may damage the layer.
  • Do not apply ReduFlex Blue to a wet surface or during rainfall because this may create an uneven layer of coating on the glass.
  • Do not apply when rain is expected within 12 hours since the coating is highly likely to be damaged or to be washed away completely.

AntiReflect

What’s the best time to spray AntiReflect?

AntiReflect lasts for two years, so it is best to apply it right after the summer. That way, you benefit from maximum light gain during two darker seasons. 

How do I clean a greenhouse roof coated with AntiReflect?

A mild detergent can be used to clean the AntiReflect-coated greenhouse roof. The detergent should be sprayed on the greenhouse after which it should rain off. Do not use any brushes in combination with a cleaner or detergent. Do not use GS-4 because that will remove the AntiReflect layer. The ReduSystems coatings can be removed by using ReduClean and letting it rain off without damaging AntiReflect.

Do I have to remove AntiReflect before re-applying?

Yes, at the end of AntiReflect’s useful life, it can be removed by using GS-4. We advise you not to dispose the residue in the irrigation basin.

How many times can I brush AntiReflect?

We recommend brushing AntiReflect a maximum of 10 times per year. You should use water and soft brushes only. Never use any cleaning product in combination with brushing. 

How do I apply AntiReflect?

Note: AntiReflect can only be applied by certified contractors. To find a certified contractor or become a certified contractor yourself, please contact sales@redusystems.com.

 

Application instructions:

  • AntiReflect has to be sprayed on a clean and dry greenhouse cover and the windows of the greenhouse have to be completely closed when the product is applied.
  • AntiReflect must be applied very evenly in a quantity of exactly 1,200 liters per hectare by a computer-controlled spraying machine to guarantee a constant output.
  • The effect of AntiReflect depends on the layer thickness. If the layer is too thick or too thin, the light gain will be reduced. 
  • AntiReflect is an almost transparent product and will foam slightly when sprayed onto the glass. The air bubbles will disappear by themselves.
  • Never use any non-ReduSystems products in combination with AntiReflect.
  • Please note: AntiReflect is supplied as Ready To Use (RTU) product in IBCs. Therefore, extra water should never be added to AntiReflect.

 

AntiReflect can only be applied under the ideal weather conditions:

  • An outside temperature between 10 and 25 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and a thinner layer than intended.
  • For fast drying: relative humidity (RH) < 80 %. The drying time also depends on other conditions (such as outside temperature, glass temperature and wind speed) but will be about two hours on average. The coating should be dry before nightfall because condensation may partly damage the layer.
  • Do not apply AntiReflect to a wet surface or during rainfall because this may create an uneven layer of coating on the glass.
  • Do not apply when rain is expected within 24 hours since the coating is highly likely to be damaged or to be washed away completely.

AntiCondens

How do I apply AntiCondens?

AntiCondens should be applied to the inside of the greenhouse, preferably when the greenhouse is empty. The surfaces should be clean, dry and free from other substances. AntiCondens is used in a dilution ratio of 1:15.

  1. For example, for one hectare you prepare 1,000 liters of liquid by mixing 60 liters of AntiCondens with 940 liters of clean water (dilution ratio 1:15).
  2. Apply AntiCondens by spraying from the gutter to the top of the ridge. The glass should be entirely moistened but try to avoid splashing too much water onto the glass.
  3. After application, allow the treated surface to dry thoroughly before condensation starts to form. You can speed up the drying process by keeping the greenhouse well ventilated.

Note: When AntiCondens is going to be sprayed above a crop, we strongly recommend testing the crop for phytotoxicity. Spray a small amount of diluted AntiCondens on the crop and check for any effects before starting the application.

How long does AntiCondens last?

AntiCondens is wear-resistant and will last for a whole season before fading gradually.

PipePaint

How do I apply PipePaint?

PipePaint can be used to paint untreated or new metal pipes as well as to recoat previously painted metal surfaces. When applied according to the instructions, PipePaint will not cause any damage to plants so the greenhouse does not need to be empty for it to be used.

  1. Remove any dirt, grease or rust from the surface to be painted​.
  2. Set the water temperature in the pipes to 35-45 ⁰C.
  3. Stir PipePaint before use. The product is ready to use, so there is no need to add water. ​
  4. Apply using a paint roller or a painting glove.
  5. New pipes or untreated metal should be painted twice. In the case of previously painted surfaces, one application is usually sufficient.
  6. 1 liter of PipePaint covers 75 meters of heating pipes with a diameter of 5.1 cm. ​One 15-liter bucket is enough for 1,000 to 1,200 meters of pipes.
Is a single application enough?

For used pipes, one application of PipePaint is usually sufficient. In the case of new pipes, it is necessary to apply two layers for optimal coverage. 

ReduClean

Why do I have to use ReduClean with ReduSystems products?

ReduClean is specially developed for the removal of ReduSystems coatings. Effective removal is guaranteed when ReduClean is used in the prescribed dilution and according to the instructions.

Is it possible to mix GS-4 and ReduClean to clean and remove a coating at the same time?

No. If a coated greenhouse is very dirty, first rinse the greenhouse with water to remove as much dirt as possible. Then use the recommended amount of ReduClean (250 L per hectare). If the roof is not clean yet, use GS-4 remove the remaining dirt. 

Which ReduClean version do I need?

Three types of ReduClean are available:

  • ReduClean: standard version to remove ReduSol, ReduHeat and ReduFlex Blue.
  • ReduClean DT: extra-concentrated version of ReduClean for use with a Dosatron to remove ReduSol, ReduHeat and ReduFlex Blue.
  • ReduClean for diffuse coatings: special ReduClean version to remove ReduFuse and ReduFuse IR.
I used both ReduFuse and ReduSol, which ReduClean version should I use?

ReduClean for diffuse coatings will remove both the ReduFuse and the ReduSol coating. 

How do I apply ReduClean?

ReduClean can be used to remove ReduSol, ReduHeat and ReduFlex Blue. To remove ReduFuse and ReduFuse IR, you need a special version of ReduClean: ReduClean for diffuse coatings.

  • Shake cans well before use
  • Use a minimum of 250 liters of ReduClean per ha. Add the required amount of ReduClean to clean water in a dilution ratio of between 1:5 and 1:7, stirring continuously.
  • Check whether the waterways and surroundings are suitable for the inflow of ReduClean.
  • Apply ReduClean evenly to the greenhouse surface, preferably using a spraying machine.
  • Rainfall will rinse away the shading material. Therefore, only apply ReduClean when a considerable amount of rain is expected within one week. Greenhouses with specific types of polycarbonate, acrylic or plastic film should be rinsed with water after about 15 minutes as removal by rain can be insufficient.
  • When rinsing mechanically: allow ReduClean to soak in for at least 15 minutes before brushing.
  • It is not advisable to use rooftop sprinklers for rinsing purposes.
  • Check the usability of the irrigation water in the basin after inflow of ReduClean, since rinse water can alter the pH level of the water in the reservoir. It is advisable to monitor the pH level of the water and make the necessary adjustments prior to use, or to close the reservoir inlet during rinsing.
  • Never use any other cleaning brands to remove ReduSystems coatings.

The ideal weather conditions for applying ReduClean

  • An outside temperature between 5 and 20 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and lead to partial or non-removal of the coating.
  • Humidity < 90 %. Do not apply ReduClean to a wet surface or during rainfall.
Why does the water turn white after using ReduClean?

Our removable shading product ReduSol is based on chalk, which is an environmentally harmless mineral. When ReduClean is used, the coating dissolves and the chalk residue causes white discoloration in the water. To avoid this, you can take the precautionary measures as described on the product packaging. 

How do I apply ReduClean DT?

ReduClean DT is an extra-concentrated version of ReduClean for use with a Dosatron pump.

  • Shake cans well before use

    • In case of 2,000 liters of spray liquid per ha, Dosatron at 5%
    • In case of 1,800 liters of spray liquid per ha, Dosatron at 5.5%
  • Check whether the waterways and surroundings are suitable for the inflow of ReduClean DT.
  • Apply ReduClean DT evenly to the greenhouse surface using a spraying machine.
  • Rainfall will rinse away the shading material. Therefore, only apply ReduClean DT when a considerable amount of rain is expected within one week. Greenhouses with specific types of polycarbonate, acrylic or plastic films should be rinsed with water after about 15 minutes as removal by rain can be insufficient.
  • When rinsing mechanically: allow ReduClean DT to soak in for at least 15 minutes before brushing.
  • It is not advisable to use rooftop sprinklers for rinsing purposes.
  • Check the usability of the irrigation water in the basin after inflow of ReduClean DT, since rinse water can alter the pH level of the water in the reservoir. It is advisable to monitor the pH level of the water and make the necessary adjustments prior to use, or to close the reservoir inlet during rinsing.
  • Never use any other cleaning brands to remove ReduSystems coatings.

The ideal weather conditions for applying ReduClean DT

  • An outside temperature between 5 and 20 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and lead to partial or non-removal of the coating.
  • Humidity < 90 %. Do not apply ReduClean DT to a wet surface or during rainfall.
Can I allow wastewater containing ReduSol and ReduClean to flow back into my irrigation basin?

We advise you to check the usability of the water in the irrigation basin after any inflow of ReduSol and/or ReduClean. Check whether the water is cloudy (which can indicate the presence of calcium carbonate) and measure the pH value to determine whether the water can be used for irrigation purposes. If you plan to acidify the water before use, the combination of the acid with calcium carbonate could form bicarbonate, which can be harmful to certain crops such as roses. In this case, you should wait until the chalk has sunk to the bottom of the basin before using the water for irrigation purposes. We advise you to monitor the pH level of the water and make the necessary adjustments prior to use, or to close the reservoir inlet during removal of a coating.

How do I apply ReduClean for diffuse coatings?

ReduClean for diffuse coatings is a special version of ReduClean to remove ReduFuse and ReduFuse IR.

  • Shake cans well before use
  • Use a minimum of 250 liters of ReduClean for diffuse coatings per ha. Add the required amount of ReduClean to clean water in a dilution ratio of between 1:5 and 1:7, stirring continuously.
  • Check whether the waterways and surroundings are suitable for the inflow of ReduClean for diffuse coatings.
  • Apply ReduClean for diffuse coatings evenly to the greenhouse surface using a spraying machine.
  • Rainfall will rinse away the shading material. Therefore, only apply ReduClean for diffuse coatings when a considerable amount of rain is expected within two days. Greenhouses with specific types of polycarbonate, acrylic or plastic films should be rinsed with water after about 15 minutes as removal by rain can be insufficient.
  • When cleaning mechanically: allow ReduClean for diffuse coatings to soak in for at least 15 minutes before brushing.
  • It is not advisable to use rooftop sprinklers for rinsing purposes.
  • Check the usability of the irrigation water in the basin after inflow of ReduClean for diffuse coatings, since rinse water can alter the pH level of the water in the reservoir. It is advisable to monitor the pH level of the water and make the necessary adjustments prior to use, or to close the reservoir inlet during rinsing.
  • Never use any other cleaning products to remove ReduFuse and ReduFuse IR coatings.

The ideal weather conditions for applying ReduClean for diffuse coatings

  • An outside temperature between 5 and 20 ⁰C.
  • Wind speed of less than 2 m/s (7 km/h). A strong wind will cause product loss and lead to partial or non-removal of the coating.
  • Humidity < 90 %. Do not apply ReduClean for diffuse coatings to a wet surface or during rainfall.
What happens if ReduClean comes into contact with my crop?

ReduClean has a high pH which can damage crops, so you should always prevent it from dripping/spraying onto your crop.

How soon must it rain after the application of ReduClean on the greenhouse?

After the application of ReduClean for diffuse coatings (for ReduFuse and ReduFuse IR), it should rain fairly heavily within two days, and in the case of ReduClean or ReduClean DT (for ReduSol, ReduHeat, ReduFlex Blue) within one week. If it does not rain within that period, you will need to rinse the ReduClean off using a generous amount of water.

Can I discharge wastewater from ReduSol and ReduClean into the surface water?

ReduClean and ReduSol do not contain any chrome. We advise you to check with your local authorities whether these products may be discharged into the surface water. The discharge of large quantities of wastewater into small waterways such as ditches filled with standing water can have an effect on aquatic life. Therefore, you should always use the recommended dilutions and be aware of circumstances such as the amount and flow of water in the waterways. 

I have used roof sprinklers and now I cannot remove the coating. What should I do?

The roof sprinklers have caused a layer of chalk or iron to form on top of the coating. First, you should use a citric acid to remove the layer of chalk or an oxalic acid in the case you have a layer of iron. You can then use ReduClean according to the instructions. 

Can ReduClean affect the aquatic life in my basin?

This depends on the amount of product and size of the basin. A high concentration of ReduClean can have an effect on the well-being of fish and other aquatic creatures. Therefore, you could always contact your ReduSystems account manager for a customized advice.

Can I use ReduClean to remove non-ReduSystems shading products?

ReduClean is specially developed for the removal of ReduSystems coatings. In practice it is also used to remove other shading products, but we can give no guarantee of its effectiveness in such cases.

GS-4

Does GS-4 work on plastic?

No. GS-4 and GS-4 Xtra are only suitable for use on glass.

Is it possible to mix GS-4 and ReduClean to clean and remove a coating at the same time?

No. If a coated greenhouse is very dirty, first rinse the greenhouse with water to remove as much dirt as possible. Then use the recommended amount of ReduClean (250 L per hectare). If the roof is not clean yet, use GS-4 remove the remaining dirt. 

How do I apply GS-4?

GS-4 can be used on both the inside and the outside of a glass greenhouse. GS-4 is not suitable for plastic greenhouses. For use on tempered glass, test the product first on both the inside and the outside of the same sample pane. Assess the clarity of the glass after rinsing of with water and drying.

  1. The temperature needs to be above 5 degrees Celsius. Do not use GS-4 during sunny weather, as the product will dry too fast and damage the glass.
  2. Dilute GS-4 with clean water according to the level of contamination on the glass:
  3. Mild contamination = mixing ratio 5% of GS-4: 100 liters of GS-4 + 1,900 liters of water per ha
  4. Heavy contamination = mixing ratio 10% of GS-4: 200 liters of GS-4 + 1,800 liters of water per ha
  5. Apply GS-4 uniformly to the glass using appropriate spray equipment.
  6. Allow GS-4 to react for a while, but do not let it dry on the glass (pay attention when the weather is warm) to prevent damaging the glass.
  7. Rinse the glass surface thoroughly with clean water.
  8. After use, flush the equipment with water.

Note: When using on the inside: only apply in an empty, crop-free greenhouse. Do not use in the vicinity of fluoride-sensitive crops. 

How do I apply GS-4 Xtra?

GS-4 Xtra is a concentrated version of GS-4. GS-4 Xtra can be used on both the inside and the outside of a glass greenhouse. GS-4 Xtra is not suitable for plastic greenhouses. For use on tempered glass, test the product first on both the inside and the outside of the same sample pane. Assess the clarity of the glass after rinsing of with water and drying.

  1. The temperature needs to be above 5 degrees Celsius. Do not use GS-4 Xtra during sunny weather, as the product will dry too fast and damage the glass.
  2. Dilute GS-4 Xtra with clean water according to the level of contamination on the glass:
    • Mild contamination = mixing ratio 2.5% of GS-4 Xtra: 50 liters of GS-4 Xtra + 1,950 liters of water per ha
    • Heavy contamination = mixing ratio 5% of GS-4 Xtra: 100 liters of GS-4 Xtra + 1,900 liters of water per ha
  3. Apply GS-4 Xtra uniformly to the glass using appropriate spray equipment.
  4. Allow GS-4 Xtra to react for a while, but do not let it dry on the glass (pay attention when the weather is warm) to prevent damaging the glass.
  5. Rinse the glass surface thoroughly with clean water.
  6. After use, flush the equipment with water.

Note: When using on the inside: only apply in an empty, crop-free greenhouse. Do not use in the vicinity of fluoride-sensitive crops. 

Can I dispose the rinse water with GS-4 to the irrigation basin?

No, GS-4 contains fluoride which can be harmful if it comes in direct contact with crops.
