Growing "indoor" outdoors

Wow! Its been almost 6 years since i last visited this site. Good to be back lol! That was one helluva nap :stoned:

My question was about growing in an outdoor wooden shed-type building I am going to work on. I'm going to build it stout with a door, cement foundation, etc. In other words I'm not gonna half ass slap something together. It will be secure.

The problems I foresee are with temp. I live in GA, down South, so it could easily get triple digits and high 90's for long periods in the warmer portion of the year but right chilly for a few months as well. We really only have two seasons.

Let"s say the shed is about 150 sq ft. Can you guys give me some venting options to make this work and also do you think a few 600W HIDs will keep the girls warm in the cooler times or heavy insulation, etc.?

I'm not sure this is practical, but i hope so. Any advice is very much appreciated and I thank you in advance!

By the way, this is all hypothetical and for fun only as a thought experiment :thumbsup:

i'm in n. Alabama same weather. consider 8" or larger pipes 3'to 4' underground for both intake and exhaust air.these will cool the summer air and heat the winter air. where i'm at the temp that deep is 56 degrees year round.
