Oh and another tip.. if you go to a hydroponics shop be ready to talk about that tomato plant you are growing and the bell peppers you want to get started.. seriously, the guy in the shop started into me with twenty questions and I know I failed.. I could tell he was questioning me and he acted different after. I was pretty rattled and by the time I left the store with the goodies I forgot which freakn car I drove to the shop (not mine of course) and was walking around the parkinglot aimlessly looking for a car i recognized. It was not a smooth day for me
