Depends on how well sealed the tent is. I can do an entire grow with a 20lb tank. You don't need 1200 ppm for the entire grow I find only the first 4-5 weeks of flower. Usually I run about 800ppm. You need the lighting to be able to get full benefit of CO2 and that over 1000ppfd. I veg at about 800ppm then 1100-1200 for 4-5 weeks and down to 600 the last 2 weeks of flower.

My room is completely sealed and not that big it's actually built out of styrofoam and 2x2. I use an autopilot controller.
