C02 question

Hey guys How long would a 20lb co2 tank last??? Im in a 4x8 tent wouldnt be running system when lights are out. Also I would need co2 tank,regulator and controller correct??? Thanks

yes to the equipment, and about 30 days if it's sealed good

SAVE YOUR $$$ Hook up a series of bottles or old nutrient containers with 1cup of sugar and 1pkt of yeast and then add water NOT ICE WATER EITHER CAUSE that'll kill the yeast. This is a set-up that we use for up to 2weeks.I add more bottles after 1week and rotate after that.The fifi's will luv it and you'll see overnight success.

just asked a buddy this today about my 4x6 room & got the same answer.
as for the yeast & water, its a lot of work and a lot of stink to deal with & while it will raise your CO2 some, it wont work as well as a bottle.
