My plants seem to be doing pretty well. One question and it's a dumb one. When do I move my light up? Is it only when my plants are getting closer to it? I know how to tell they're too close but do I just wait till they're starting to get too close and then move it up? Any other reasons I should be moving my light up or down? Yes i know this is pretty dumb

Hold your hand under your light for 30 seconds ay canopy level. If it feels hot move the light up.

Don't bad mouth crappy cfl's if you haven't tried'em.They work great!!!You just have to know what your doing.Hps put off a lot of heat,causes bleaching,bulbs don't last as long.......etc. etc.
Hey folks thanks a lot. Yeah they are hps. Appreciate the advice. I was getting worried because I haven't moved my lights up in awhile but it's because I didn't move it down enough after they were seedlings so they haven't grown close enough yet. Basically I am a muppet!! Thanks folks

I use a 400W HPS, and I found the "hold your hand under" technique did not work for me. I thought the amount of heat was just fine! But I burned my plants. They recovered, but it looked awful and all dried up for a while.
I now use a tape measure. I aim for 18 inches from top of plant to bulb, then let it get to about 16 inches (sometimes 14) but then raise the light back to 18. That hasn't failed me yet.

I can get my as close as ten dude. I suppose it depends on what temps you've got to deal with in your tent but the closer the better

I have noticed that some people have better capabilities here than I do! I might also not have the best venting system...I think it's good at best, not great. And that plays a role, too. It's a small tent...
