damn ranch houses lol. ya i got my 600s ( i only have one, i gave my dad the other ) off craigslist for 100 bucks for the pair , they are home made white reflectors, and are kinda tweaker made but they work so i cant complain and then i got the 400 mh for 70 from again craigslist, and my friend works at a light distributor for Sylvania and they " loose " a lot of bulbs lol so i have new bulbs at least . The shed would be a good idea depending on the shed and how your weather is there. heres some of my autos i got goin from attitudes august promo
link is in my sig, i love CFL's btw the way i use them for veg rather then t5's i have a custom fixtures i made from spare lamp parts and what not that can hold 18 bulbs in a 4 x 2 rectangle area, it can support veg for 10 plants easy lol
