I frequent this garden shop and they are helpful and knowledgable every time. PLUS there's a super hot girl working the register. This to me is ,WIN,WIN,WIN!the prices are a little high but they give you at least a 20% discount when you check out so it evens out. Take it from a pro... They got what you need, if you can't afford it then maybe hydro gardening isn't the hobby for you. If you think they are rude, buy a book so you don't have to burden them with all your silly questions.
