From a fellow grower: I am building a greenhouse for my plants, will this glass let in enough light?
I have no idea what that rating is, but generally, with ‘glass’ greenhouses, generally more than enough light gets that it’s not your limiting factor… In fact all too often too much light generally gets in during the summer months requiring shading to block it, venting off excess heat and pumping up the humidity, or else you toast the plants… I only know one person personally that uses a dedicated greenhouse to grow (not to be confused with hoop tents, hot boxes or whatever) and he has a shade cover over it all summer, and on any real sunny day the fog cooler and exhaust fans run all day just to keep the temps down…
