5000 lumens/ft2 is the figure I see all the time as the minimum for optimal flowering. The data on lighting is bewildering and everyone seems to have their own ideas. I'm just regurgitating the common info that I've come across. Also I don't use cfl and things may be different when using that kind of light. The other variable here is distance from the light source, closer=more lumens. When people rate a bulb by lumens I believe they are measuring at 1 ft. distance. Hopefully someone with more experience with this (esp. cfl) will answer. But you should google it. There is a ton of info about this out there. Also the Grow FAQ on this site discusses this.
Chromophore Reviewed by Chromophore on . What do you think? Hi all, I am currently doing my own small indoor grow and when i say small i mean only one plant. Was wandering if someone could tell me how my weed plant is doing from the pics below. Its been growing for a little over 6 weeks now and is getting bigger every day. Btw the bottom have yellow spots which then turn yellow and shrivel up and die as you will see in the pics Rating: 5
