Feel like I should do some cool diagram in Paint, but I don't have the chops.

I didn't notice that your hood was cooled- so you like to fly it in pretty close? Doing large plants, I've always found that things worked best if I flew the reflector a little high, to keep the plants from shading each other- but you need headroom.

I have no idea why this is sticky.
I keep the light a good couple feet from the top of the canopy, I've experienced a problem on my first grow with the colas bleaching out on me, sucks when you lose the best part of the plant. Plus yeah I dont want them shading each other out.

And as for it being sticky, I have no idea, but it sure has been an interesting thread so far, I'm sure many people can learn a thing or two from it.
