Buy a grow tent! I'm with ya on everything, trust me, but the two things I'm absolutely updating are my lights (going to led at some point) and a grow tent. If you hit the right place, you can get a combo deal at a fantastic price. From my perspective, the tent/closet cost differential is negligible whereas the pain in the ass to ease and speed ratio strongly favors a premade, professionally lined , thought out ventilation tent. Plus then you gotta seal the closet, wire it, ventalize it.... Just my 58¢. Looking good!
