i using ufos myself they need to be as close as possible thats the whole point, i keep mine inches away and the growth is robust and buff just make sure they get enough water... just my two cents
Ya, I'll upload pics of where the lights are now. They are about 5-6 inches from the tallest plants. I've got them watering 3 times a day when the lights are on: 6 am, 12 pm, and 6 pm. You aren't supposed to water when the lights are out right? The rockwool cubes that the clones are in hold a lot of water and there isn't much heat so they don't dry out very fast.
