So I bought a tent to setup in my spare room, inside the 8x4 tent I have started flowering 6 plants under a 1000 watt hps, The hood is ducted from outside the tent to blow outside air (room temp) over the bulb and exhaust outside the tent (back into the room). My first day setting up the tent I realize a terrible flaw, the radiant heat from the hood pushes the inside temperature up to 90+ degrees easily, the quick fix was to open the top half of the tent doors to allow the hot air to escape, but if the tent is going to be open half the time, why do I even own a tent?!

The remedy I found, was to remove the input duct so the inside (warm air) is pulled through the hood and exhausted outside of the tent, this easily brings the temperature back down to roughly 2-5 degrees above regular room temp (about 78) and now the tent works great for keeping light away from my flowering buds.

Now the new problem I have is this: In the closed tent I was administering CO2 from a tank and regulator inside the cieling of the tent as I hear CO2 is roughly 3x heavier than regular air and will sink, fans inside the tent stir the air around a bit but when tent doors are open I have to assume I lose C02, when I pull air from inside the tent, pumping it out I have to assume I still lose C02. My new question is this: if I administer CO2 near the bottom of my tents and the fans stir it around will I get some benefit out of it before its sucked out of the light hood? Am I just spinning my wheels here pumping out CO2 that I paid for?

Appreciate those who read through and any input given
