I started my plants under CFL bulbs and they were short and dense. When I moved them to a Viparspectra "600" LED light they grow very long stems. Internode spacing is 3 to 3-1/2 inches even though the lamp height is what they recommend (18-24 inches). I moved the lamp down and the leaves seemed to wilt, so I went back up. The reviews suggest people are happy with these lights, but maybe we're all newbies. Why are these plants so tall? After topping, the new tops are now 3-1/2" above the cut.

Leggy plants on LED lights?
