curious old fart

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
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.
