Co2 help

ok, i have some questions, one is where would you go to just go and get a Co2 tank preferably a cheap one cuz im on a budget haha. and that timer thing that you need for that stedy flow.

Go to a local hardware store, and tell them you need a 20 Lb Co2 tank for a Kegulator. As for the regulator, you can buy them off hydroponic sites on the internet.

Or if you're on a budget, just spend some more time breathing in the room.

hahahahhahahaha just breathe on the plants..

If your on a budged I'd look into other methods, the co2 regulators are rather expensive..
Sugar water and yeast?
there are fizz tabs u can buy
spraying tonic water?

how much are tanks and cant you just like turn the nozzle on the top for an ammount of time and then juss go in and tighten the nozzle back up to stop tha flow? that kinda sounds like a bad idea but watever.
