its about 12 inches from the light, i brought it in from outside 3 days ago, (was growing on the balcony before i bought the 1000watt) i probably should have mentioned this in the first place
thats the problem with 100's though, unless thery are air cooled you are fucked cuz you have to raise your light and succomb to the evil stretchies, shoulda got the 600watt model IMO
