AntiCondens Glass   

A coating applied to the inside of the greenhouse cover, preventing large condensation droplets from forming and replacing them with a fine water film instead. This lets more light into the greenhouse and reduces disease pressure from Botrytis and other moisture-related diseases. 

Suitable for glass greenhouses, and wear-resistant for the full season. It wears off naturally over time, so there's no active removal step. Simply clean the surface and reapply when needed.

More Light, Less Disease Pressure 

Large condensation droplets block light and create the damp conditions where diseases like Botrytis, Mycosphaerella and mildew thrive. By replacing those droplets with a fine, even water film, AntiCondens Glass lets more light reach the crop and reduces disease pressure caused by falling droplets. 

AntiCondens Glass also helps save energy and improve production, since more usable light reaches the crop without extra heating or lighting. When spraying above an active crop, we recommend testing a small area first to check for any sensitivity before treating the full greenhouse.

More Light In 

AntiCondens Glass improves light incidence by 5 to 7% by replacing large condensation droplets with a fine, even water film. That extra light supports better crop production.

Fewer Fungicides 

Growers using AntiCondens report cutting fungicide use by 80 to 90%, thanks to better control over moisture-related diseases like Botrytis. Less droplet fall also means less crop damage.

Decades of R&D 

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

Application

Apply to the inside of the greenhouse, preferably when it's empty, on a surface that's clean, dry and free from other substances. Spray from the gutter to the top of the ridge until the glass is fully moistened, avoiding excess splashing. Keep the greenhouse well ventilated and heated to speed up drying. If spraying above an active crop, test a small area first to check for phytotoxicity. 

Coverage and Dosage

Each 20-litre can of AntiCondens Glass is diluted with water at a ratio of 1:15. By machine, use 6 cans per hectare (3 per acre), mixed with 1,800 litres of water per hectare (190 US gallons per acre). By hand, use 3 cans per hectare (1.2 per acre), mixed with 900 litres of water per hectare (96 US gallons per acre).

Removal

AntiCondens Glass isn't actively removed. It wears off naturally over the season, so all that's needed before reapplying is to clean the surface first.

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 AntiCondens Glass suitable for?

Glass only. A separate version, AntiCondens Plastic, is available for plastic greenhouses.

How is AntiCondens Glass removed?

It isn't actively removed. It wears off naturally over the season, so all that's needed before reapplying is to clean the surface first. 

Does the greenhouse need to be empty to apply AntiCondens Glass?

 It's best applied when the greenhouse is empty. If a crop is already in place, test a small area first and check for any sensitivity before spraying the full greenhouse. 

How long does AntiCondens Glass last on the greenhouse cover?

If applied well, it stays active for the whole season. It gradually wears off over time, so it may need reapplying before the season ends. 

Can AntiCondens Glass be used at the same time as AntiReflect?

Yes. AntiReflect is applied to the outside of the glass and AntiCondens Glass to the inside, so both can be used together to make the most of available light during low-light periods. 

What is the difference between AntiCondens Glass and AntiCondens Plastic?

Both prevent large condensation droplets and replace them with a fine water film. AntiCondens Glass is for glass greenhouses and improves light incidence by 5 to 7%. AntiCondens Plastic is for plastic greenhouses, improves light incidence by 15 to 20%, and also prevents "inside rain."
