Wow.. thank's for all the information..

So Ski.. you think I should get my whole growing area set up.. and get all my bulbs and equipment.. and then start thinking about what seeds to buy etc?

Sounds like a good idea..

Do get maximum light I think I'll have to construct an enclosure in my attic seeing as it's a large space.. How big do you think I should make it? I'm trying to think of the best stuff to do it with..

Something like this..?
