The only problem with that distance with LEDs is the blues and res don't blend very that close. We have three Procyons 24" above ours. Still seedlings though. They'll be about a foot closer during veg depending on stretch.

Glad to see some more LED believers. I've also seen in two other led grows where they claim higher potency levels, and isn't that what we(smokers) all truly want.:smokin:

edit: but the bulbs might be packed tighter in the screw in models. so what do I know... lol
