    I can't think of the coverage I would get as I've never used LED's before. Give me a HPS and I'm well away haha

    I've far from made my mind up though, just trying to understand more than anything. Please don't take my questions as a challenge to your personal experience, i'm trying to draw from it.


    The way I see it is like this. I have 17" of height to use, 4" is take up by the medium/system, 2" for medium to screen, 2" to hang the light and 6" distance from the light. that leaves me around 3.5" to grow my canopy in a safe space? Would you agree with that?

    I did that for some seedlings. A 13W domestic LED bulb. Kept them going for about a month or a little over.
