I hate hate HATE the yeast way. I used to do it and it was.... gross. Smelled like bad beer, messy, fluctuated co2 like crazy and you cant turn it off at night. waste.
The paintball method last a long time. a 20oz tank will last 3 months.
I suggest that if anyone wants to get some great, cheap, rare, easy, hard, any kind of plant, go check out plantedtank.net like I said some people GIVE AWAY free plants. all you pay is shipping.
Im already giving away 1 small package to a guy here haha
