Tropfrog Posted July 27 Report Share Posted July 27 I don't know what is best. But my greenhouse is polycarbonate and it work fine. I don't think uv light is a vital part of the photosyntesis action spectrum. Br Magnus Quote Link to comment Share on other sites More sharing options...

Blue and red is the most powerful waveleangths but not the only ones utilized. The only ones less important seems to be green, UV and IR.

BeyBlade Posted July 27 Author Report Share Posted July 27 I think it is not normal for a plant to grow without UV light. Quote Link to comment Share on other sites More sharing options...

Obviously all plants in situ gets uv light so in that sence it is normal, yes. Most plants grown in greenhouses or in indoor setups do not get any uv. So in cultivation it is normal to grow without UV. Most growers grow plants far bigger and healthier than in situ plants. That gives a hint that UV, normal or not, is not a key in success.
