I currently run a Hombox Small (0.8 X 0.8 X 1.6) and considering a simialr idea once am confident with a couple of grows under my belt.Depends on how much space you have, something that small would be better than a PC grow and you can use auto's
You can get a DR40 and a DR60, use your DR40 for seedlings, clones or mothers and flower in your DR60. Also depends on your budget
I will be using an 250HPS, would probably fit into a small DR40 and DR60 really well. I was reading in another area of the forum some guys are using CFL 200's red and blues or something, maybe worth checking out? I have found having a really good read through posts of the experienced guys will not only give you idea's but can also tell you that your own ideas may not be ideal. Anyway, good luck man, hope you pick your perfect tent and get a nice batch grown what ever your methodfor autos only and i would probaly use t5s as the light source four seperate t5s
