Looks like the CO2 generator bubbles through something (drying agent?) before heading of to work. Nice DIY gas generator. The evil scientist in me shows respect...
Yeah just goes through a water filter so you can see if it is still working, just bubbles then releases up to hose to fan, I’ve gone completely different (and more expensive) with my heater it’s an electric fan heater, now I place this on the floor so it moves the co2 around as co2 is heavier than air, only been a week, room is completely sealed and plants r going well thus far[emoji106]
