It’s enhanced photosynthesis based on a simple fact: that red light is best for plant growth. Renolit Ondex developed BIO2 HP OPTIRed sheets as spectral converters in greenhouses. From algae to vegetables to flowering plants, OPTIRed reduces plant stress, making them more resistant to diseases and pests while minimising the need for fertilisers and plant protection. OPTIRed maintains its effectiveness for 10 years, thanks in part to bi-stretching, a unique manufacturing process stretching the sheets in both directions increase durability.
