This is perfect for a small area. Go to Wal mart buy one gallon of White vinegar and a couple pounds of baking soda. The hard part is mixing them. Just a little bit of baking soda make the vinegar fizz. That fizz is CO2. If you get a plastic milk jug, punch a small hole in it's lid, then mix in the baking soda. Put the top on quickly and shut the door to your closet. Just add some more soda every couple of hours and give the jug a shake. It works! Just be careful you don't add to much soda to quick. If you do it will shoot suds and vinegar everywhere. so you have to play with the amounts. If you google "ask Erwin" at Atami. ask they will give you a sample of Bloombastic that stuff works even better than co2 and it's easyer to play with. Happy trails
cdouglas869 Reviewed by cdouglas869 on . CO2 solutions for micro grows I'm growing in about a 1.4x1.4 foot area where the plant pretty much takes up the entire area. I've heard how much CO2 can help a grow throughout all stages of development and thought it might be worth it to add some CO2 capabilities to my next grow. Do any of you have ideas about CO2 sources that are available short of just buying a cannister? Thanks. Rating: 5
