ReduCompact 

A removable coating that transmits more blue light relative to red, encouraging compact plant growth and reducing the need for plant growth regulators. This is especially effective on ornamental crops such as Pelargonium, where it helps control plant height naturally. 

Suitable for glass, acrylate, polycarbonate and plastic film greenhouses, and highly wear-resistant in higher concentrations, with the dose adjustable to match your crop and climate.

Compact Growth, Naturally 

By increasing the ratio of blue light to red light, ReduCompact encourages plants to grow more compact without added chemicals. This has shown positive results on ornamental crops such as Pelargonium, helping control plant height and reducing the need for plant growth regulators.  

Wear resistance depends on the concentration applied, and above-average rainfall can wear the coating faster. It can be removed at any time with ReduClean. When layered with another ReduSystems coating, ReduCompact should always be applied first, as the layer underneath.

Adjustable Shading   

Net shading can be adjusted up to 25% at higher doses, so growers can fine-tune the effect to match their crop and climate rather than a single fixed level.

Blue-to-Red Ratio 

At the highest dose, ReduCompact shifts the light ratio to 3:2 blue to red, the level shown to encourage the most compact growth. A lower dose gives a gentler 5:4 ratio instead.

Decades of R&D  

ReduSystems has been developing greenhouse coatings since 1986. That experience shapes every product, including ReduCompact.

Application

 Apply only under fast-drying conditions, above 10°C, with relative humidity below 80%. 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 ReduCompact is mixed with water before spraying. Growers typically use between 16 and 25 buckets per hectare (6 to 10 buckets per acre), depending on the light-ratio shift 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 1,200 litres per hectare (128 US gallons per acre) by machine, or 1,500 litres per hectare (160 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, 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 ReduCompact suitable for?

Glass, acrylate, polycarbonate and plastic film. 

How is ReduCompact removed at the end of the season?

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. 

Can ReduCompact 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 ReduCompact 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. 

Can ReduCompact be layered with other coatings?

Yes. ReduCompact should always be applied first, as the base layer. We advise against layering ReduCompact with non-ReduSystems products, since different cleaning methods can cause problems when it's time to remove the coatings. 

What is the difference between ReduCompact and ReduFlex Blue?

Both are photo-selective coatings that change the light spectrum rather than simply reducing it. ReduCompact increases the ratio of blue light to red light, which encourages more compact plant growth and is especially effective on ornamental crops like Pelargonium. ReduFlex Blue increases the ratio of red light to blue light instead, which can increase stem length in sensitive crops like roses.
