Wow. A lot happened this week - I found out that Tommy Chong likes to eat at my restaurant at least once or twice a week. This week I was his server and he hooked me up with some homegrown. Definitely the highlight of my week, if not month.
That being said, I also built my own LED light using suggestions from my friends at rollitup and ilovegrowingmarijuana.
@MG2009, I have holes drilled 2 inches above the bottom to create a reservoir for the roots (kind of hydroponic) so the perlite is just the medium I chose to sit them in, primarily because it dries out fast.
