I'm stacking two bare 600w HPS with a 14" fan blowing the heat up. How for should the plants be away from the stacked lights to keep from burning?
Thanks!
Thanks!
For 600w, I would go with a 30-36" circle around the plants so at least 15" from the bulb all the way around..
Sure that makes sense, plant numbers and size factor in, assuming the size and numbers allow what would be bad about having them as close as possible, even if its < 12 inches.
Multiple lamps stacksed are even better than single lamps... by increasing the light intensity farther from the lamps...
