ReduHeat

A removable coating that reflects infrared radiation while keeping grow-light transmission high, ideal for crops that thrive under intense light but struggle once temperatures rise. Unlike coatings that shade the whole spectrum, it targets heat specifically, so crops keep converting available light into steady growth.

Suitable for glass, acrylate, polycarbonate and plastic film greenhouses, it's highly wear resistant and dries faster than other infrared-reflecting coatings in the range. The level of heat reduction can be adjusted by dose to match your crop, climate and greenhouse type.

Reliable Heat Protection Without Losing Light

Excess heat causes stress that can slow growth and affect crop quality during periods of intense sun. Because the coating targets infrared radiation specifically rather than the whole spectrum, it brings down greenhouse temperature while keeping PAR light transmission high, with the level of protection adjustable by dose to suit your crop and climate.

The coating stays effective for the full season and does not need to be reapplied partway through. It also becomes transparent again when wet, letting more light through during rainy periods.

Flexible application

Applied by drone, machine, helicopter or by hand, so growers can use the equipment they already have.

All greenhouse types

Suitable for glass, acrylate, polycarbonate and plastic film greenhouses, and effective across a wide range of crops depending on climate.

Apply only under fast-drying conditions, between 10°C and 25°C (50-77°F), with relative humidity below 80% and wind speed under 2 m/s. Mix with clean water in the tank and apply evenly across a clean, dry surface. Do not apply if rain is expected within 24 hours.

Each 15kg bucket of ReduHeat is mixed with water before spraying. Growers typically use between 15 and 25 buckets per hectare (6 to 10 buckets per acre), depending on the level of heat reduction needed for their crop, climate and greenhouse type.

The amount of water used depends on how you apply it: about 1,000 to 1,500 litres per hectare (107 to 160 US gallons per acre) by machine, or 1,700 to 2,000 litres per hectare (182 to 214 US gallons per acre) by hand. For guidance on the right dose for your specific situation, reach out to a ReduSystems specialist.

Removed with ReduClean, diluted at 250 litres per hectare (26 US gal per acre) at a ratio of 1:5 to 1:7, sprayed evenly over a dry surface.

Apply when a considerable amount of rain is expected within a week, and the rain will wash the coating off. Avoid applying during rain, and note that roof-sprinklers used for cooling can cause removal problems.

ReduClean

Removes ReduSol at the end of the season, so the greenhouse is ready for the next one.

ReduSol

Can be layered on top later in the season for added protection once summer heat peaks.

SprayChalk

Adds a temporary top-up layer during short, extreme heat peaks, without disturbing the coating underneath.

Why ReduSystems

The Right Solution for Every Season

Light is the most variable factor in greenhouse growing, yet many growers do not yet use it fully throughout the year. We help growers protect, improve and adjust crop performance in every season, with a solution matched to each stage of the growing cycle.

With decades of experience in light spectra, PAR and photosynthesis, we adapt every solution to the grower's crop, greenhouse and location. Our advice is based on science and real-world results, not guesswork.

Frequently asked questions

Glass, acrylate, polycarbonate and plastic film.

With ReduClean, diluted at 250 litres per hectare (26 US gal per acre) at a ratio of 1:5 to 1:7, applied when a considerable amount of rain is expected within a week so the rain washes the coating off.

It can be applied by drone, machine, helicopter or by hand. Application methods and dilution rates can vary, so reach out to our team for specific instructions and support.

This depends on the concentration applied and the weather. A higher concentration is more wear resistant, while above-average rainfall can wear the coating faster. It can be removed at any time with ReduClean.

Yes. ReduHeat is normally applied first, as the base layer, with ReduSol layered on top later in the season for added protection once summer heat peaks.

SprayChalk can then be added as a topmost layer for short, extreme heat peaks. We advise against layering ReduHeat with non-ReduSystems products, since different cleaning methods can cause problems when it's time to remove the coatings.

ReduSol reduces both light and heat together across the whole spectrum. ReduHeat blocks heat while keeping PAR light transmission high. ReduSol suits crops that need relief from the full intensity of the sun, while ReduHeat suits crops that want to keep light levels high.
