ReduFuse IR

A removable coating that diffuses incoming sunlight evenly across the greenhouse while also shading infrared heat. It lets light through while it penetrates deeper into the crop, reducing stress and increasing photosynthesis, while keeping the greenhouse cooler during hot periods. 

Suitable for glass, acrylate, polycarbonate and plastic film greenhouses. It is highly wear-resistant and works well for crops that need diffused light but can't tolerate too much heat, such as certain flowers and vegetables in warm climates.

Even Light Without the Heat Stress 

During warm periods, too much heat can stress the crop even when light levels are exactly right. Because ReduFuse IR shades infrared heat while still diffusing visible light evenly across the greenhouse, crops get relief from heat without losing the light they need to keep growing well. 

The coating stays effective for the full season and does not need to be reapplied partway through. When layered with another ReduSystems coating, ReduFuse IR should always be applied first, as the layer underneath.

57%

Maximum Diffusion 

HortiScatter, the measure of how evenly light is spread, can reach up to 57% at higher doses, adjustable to match the crop's needs. This helps light reach deeper into the crop, so every leaf gets more of what it needs. 

32%

Heat Reduction 

At the same dose, ReduFuse IR also reduces infrared heat by up to 32%, adjustable to match your climate and crop. This helps keep the greenhouse cooler without giving up the benefits of diffused light.

Decades of R&D 

ReduSystems has been developing greenhouse coatings since 1986, backed by ongoing research into light, climate and crop performance. This experience shapes every product, including ReduFuse IR.

Application

Apply only under fast-drying conditions, between 10°C and 25°C, with relative humidity below 80% and wind speed under 2 m/s. Mix with clean water in the tank, stirring continuously, and apply evenly across a clean, dry surface, preferably by machine.

Do not apply if rain is expected within 12 hours, and do not combine with non-ReduSystems shading products. 

Coverage and Dosage

Each 15kg bucket of ReduFuse IR is mixed with water before spraying. Growers typically use between 10 and 24 buckets per hectare (4 to 10 buckets per acre), depending on the level of diffusion and heat reduction needed for their crop, climate and greenhouse type, with machine application typically needing slightly fewer buckets than manual.

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. 

Removal

Removed with ReduClean for diffuse coatings, 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.

If the result is uneven, a second application combined with mechanical brushing can help.

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

Which greenhouse coverings is ReduFuse IR suitable for?

Glass, acrylate, polycarbonate and plastic film.

How is ReduFuse IR removed at the end of the season?

With ReduClean for diffuse coatings, 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.

Can ReduFuse IR be applied by drone?

Yes. 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. 

How long does ReduFuse IR last on the greenhouse cover?

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 for diffuse coatings. 

Can ReduFuse IR be layered with other coatings?

 Yes. ReduFuse IR should always be applied first, as the base layer, with SprayChalk added on top for short heat peaks if needed. We advise against layering ReduFuse IR with non-ReduSystems products, since different cleaning methods can cause problems when it's time to remove the coatings. 

What is the difference between ReduFuse and ReduFuse IR?

ReduFuse diffuses light evenly without shading it. ReduFuse IR does the same, but also shades infrared heat. ReduFuse suits crops that need all the light they can get, while ReduFuse IR suits crops that also need some relief from heat.
