It took me several weeks of research to design and decide what to purchase. The inside of the lab is wrapped in heavy plastic and then coated in mylar. The lamp is a medium adjust-a-wing seeing that I was designing for a max of 600 watts, and is held up by the ratchet pulley system. I went with the adjust-a-wing for the claim that it will produce higher yields and I did not find any negative reviews. I felt that the typical grow lamps were over sized and would not illuminate the area as well as the adjust-a-wing. I also got the super spreader for it which does work quite well. As for the fan it is a vertical oscillation sweep type that I got a garage sale.
