some foam insulation on the area walls would help. we get 4' x 8' x 1/2" for about $10....and a small electric heater or a portable propane-it gives off co2.i always run bare bulb and i am venting the exhuast to the veggers but its not enough mate. i have the exhaust come on at 3 hour intervals for 15 mins in the night just to exchange the air. i done that so its not drawing the cold air in all the time. it would be inefficent for me to heat the space outside the tent mate. its in a old garage exposed to the eliments all the time and not that air tight to say the least lol
