LOL. Right now i have the light about 11 inches from the top of the largest plant. I also have a large fan blowing on both the light and plants. They seem to be doing okay.

I think i messed up with one plant thought because one of my droppers came loose and dropped some water on one of the leaves. I know this can burn the plant as water magnifies the light. Its kinda yellowish at random spots on the leave. Thankfully my timer went off before it could do some real damage.

Anyone have any pics of light/water burn so i can compare?
MichiganAero Reviewed by MichiganAero on . Light Distance/Height? Hello everyone! I've been browsing the posts for a while, and although its mentioned here and there, I havent found a "guide" if you will. If there is one, point me in the way, and i'll happily read away. As for the question: Is there a general rule of thumb for light distance from the plants? I know different stages require different heights, just curious what works for everyone else. My setup is fairly small, 400w MH for veg, 400w HPS for flower. Attached are a few pics just Rating: 5
