  1. Hi folks, I'm planning a winter grow and would like to try using a closed-loop system using a dehumidifier, temperature control and Co2. As this is purely experimental for me, I'll be trying it out with just one plant in a small area. I'm looking for an effective means of producing enough Co2 to work in an unventilated area. I can't really fork out for an expensive system at this point and definitely can't have any kind of propane burner etc for safety reasons. I'd rather not burn my house down. In the future I'd like to try this but only in an outbuilding of some kind. So far I've discovered: Exhale bags Airbomz Co2 dispenser with canisters Pro Co2 buckets Making your own with sugar, bicarbonate of soda and yeast. I'm reading a lot of reviews where growers complain about these methods not really being effective enough and I'd like to achieve at least 1000 ppm if possible. Any thoughts?
