I am interested in hearing if anyone has had any success in increasing CO2 levels with alternative means other than using tanks. I've read about compost tea buckets and the hanging pads. What's the skinny?
Ive used the bags my last time around, they were called Exhale, its a sterilized compost bag that emits co2. levels were around 800 when i tested. they are said to run for about 3 months, plenty of time for anything you want to do.
So its not out of the question that if you were to run 2 bags in a 4x4 set up that you could reach those levels right?
