My friend told me about a guy who made this time release C02 system, out of a sealed bottle filled with vinegar and a tiny wick, stuffed into a canister packed around with baking soda. When the wicking fluid slowly hit the baking soda, C02 was relased gradually over time. Any experience with this? Pro's Con's? Other cheap alternatives? Thanks
Personally I just like to vent my brewing blowoff into my gro. bout the same effect .jk Actually some folks I know use a milk jug, some sugar, a pack of yeast, water, and air tubing to run to the osc. fan. and then change the H2O,yeast and sugar once a week. I'm not sold on this idea, the chemistry is sound ..but amounts cannot be controlled as far as I am concerned. ( knowledge is from brewing as opposed to growing on this judgment call so take with a grain of salt) but like most things for growing there are few "cheap alternatives" ( remember your trying to simulate nature, which is pretty much impossible.. we can only attempt it)
