Haha! Nice use of smileys to illustrate your point... I'll bet things did get warm in there! When I set up my first 400w HPS, I just threw it inside a 3x3 closet, door closed, with only one oscillating fan inside. I didn't add any plants to the closet, I just wanted to see what it would do in terms of heat. I came back in several hours later, and I could feel the hot air blowing from the crack beneath the door. Had I put any plants in there, they'd have been cooked almost instantly.

Nice job pulling a qp off one plant, that's a definite step in the right direction! Yeah, setting up a growroom right can be a chore (and very expensive depending on what equipment you go with), but after those first initial payments, things get a LOT cheaper. Even cheaper for me because I try to buy all my fertilizers in bulk, and so only have to make purchases once or twice per year. Still, even though I'm pretty happy with my current setup, I'm still prone to blowing money every time I go to the hydro shop... regardless of whether or not I need the stuff. :jointsmile:

Thanks for dropping by and lending your thoughts!
