How close should the light be? I have it at 12" right now, should I lower it?

I added a screen this weekend to start training it. For my cabinet that is 18"x48" I have almost a 50% screen coverage with the one plant and I have a dwarf plant that for some reason is 3 weeks behind. Is there a majic number that I should wait to in veg, or do you think I should switch to 12/12 now? My thought is that if this thing triples size, I am going to fill the cabinet pretty good with my 1 1/4 plants..

I am thinking for my next grow to remove the cabinet and just use the room I have the cabinet in and add a 600W to my 400W for a 1000W total. I would like to run 4-6 plants outside a cabinet to get large plants.

Thanks for the feedback.
fosomker Reviewed by fosomker on . Any Advance for nOObie I started this thread because I was concerned for the height of my plant. Well I let if veg for almost and extra week and I have also been trimming clones off to try to start them. Will the clones work taking them from this plant? Also any advice? The plant is short, only 11", but is sure is wide, over 18". It is looking nice and I was planning on switching the light over this weekend after 5 weeks of veg, any advice? I think overall it is looking good, have just bumped the nutes up to 800 Rating: 5
