Transpar

Transpar is a greenhouse shading coating built on a photoselective pigment. It favours the grow-light crops need, limits heat peaks and diffuses incoming light. The grower adjusts the dilution and the application method, then cleans the coating off with Topclear whenever needed.

High solar radiation brings the light photosynthesis needs, but also heat that can put the crop under stress. A photoselective pigment separates those two effects, letting grow-light through and sending part of the heat back.

With 20 buckets per hectare, Transpar reaches 85% PAR transmission and 25% NIR reflection. With 25 buckets, transmission moves to 75% and reflection to 40%, and with 30 buckets to 70% and 50%.

Transpar goes onto the outside of any greenhouse type, on glass and plastic roofs alike. It suits productions that want to cut heat without losing grow-light.

Application is done manually, by machine, by drone or by helicopter, on a clean and dry roof. The dilution rate and the sprayed volume are adjusted to the chosen method, the greenhouse type and the climate.

Transpar is cleaned off with Topclear, at the moment the grower chooses. Cleaning calls for at least 240 L of Topclear per hectare, diluted in 1,260 to 1,760 L of water, depending on the application method. Topclear is applied when substantial rain is forecast within the week, on a dry roof.
