Ya know it gets old listening to people trashing things they haven't tried, not everyone has $800 to drop on something as simple as CO2 enrichment. It depends on your setup plain & simple. If you have a large grow or one of these tent setups or 10bazillion cfm fans turning the air over every 10 seconds then no, sugar/yeast is not going to work. But if you have a small, sealed setup and "reasonable" ventilation sugar/yeast generation can work quite well as can small CO2 bottle/regulator/solenoid setups for 1/4 the price. Here are a couple of pics showing a setup that works very well in a ~24 cuft space with the vent fans on, no shaking required and last on average about 10 days.i ment mean mickey mouse set up ur going to get more out of a fart then that yeast crap thingy seriously vent your room with out side air will do you better 300 ppm
You know what im going to make this 2 lt bottle shit and see if my co2 monitor will even sniff it
and set things straight you be sitting there shakin the fck out of 2 lt bottle non stop
green pads: haven't tried them myself but rosenthal mentions them in his latest grow guide; they sound like they could be a cheaper option and i'm enticed by how easy they look to use.
these guys are claiming one pad for a 4x4 tent will boost your C02 to 1000 ppm for at least a week, 5$ a pad, not too shabby.

anyone have experience using these???
ive got a bottle of co2 £8.50 per refill, boyttle outside room pumped in the top through wall. Room is completely sealable so i give it a 15min blast with all extractor fans off and leave my babies drinking it up for 3 hours before switching back on - manual but cheap!
and yup, uk, sunny nw somewhere near you![]()
