E estimo Active Member Sep 22, 2008 #1 I've got about 12,000+ lumens lighting 4 plants... Is this enough light?
MrFishy Well-Known Member Sep 22, 2008 #2 There's a formula I can't recall in the faq's. It has to do with the amount of area you're lighting, like sq.ft. https://www.rollitup.org/view.php?pg=faq

desertrat Well-Known Member Sep 22, 2008 #4 not enough light unless those are awfully small plants. you want at least 3000 lumens per square ft and preferably 6000

E estimo Active Member Sep 23, 2008 #12 ok, so i got some more lights(all i could afford right now) and each plant is getting about 4600 lumens... can i still get some good growth or am i going to have to buy some sodium or mh lights?
