I have 9 sproutlings outside 24/7 now and I was wondering if it would be ok to bring them in at night and put a couple lights on them mst of the night.
I should add that they only get about 8 hours of direct light a day, so I just want to help them grow a little faster until they get to be about a foot.
If you are vegging, then this will only help speed up their growth, I have been doing this for a long time....I use 400 and 600W HIDs.... I do not know if cfls will do the same "trick"
good luck!
