for 24/7 or is 18/6 fine?
yeah i was kinda thinkn 18/6 lol hw far away..u think is ideal i had them at 4 feetputting them under the 600 should be fine as long as you can back it off as much as possable, i keep my seedlings under my bigger plants untill they get a little bigger but backing your light off as much as possable should do the same type thing. if you cant back the light off enough you might have to find a screan to put over the top of them, so they have a little shade.
i prefer 18/6.
cheers manheres a chart that might help you. i would go farther away than this says tho.
