Where is the cheapest place to get a co2 tank???

I reading they are hella expensive and wondered if there was a place i could get a tank fr cheap?

anyone?.....

ebay and craigslist foo.

check local welding shop's you can rent them for a depost and the cost of the gas
here its $50 depost for the tank

well depending how big your grow op is
if your a small grower like 400watter or 600 watter you can just get your self a paintball co2 tank preferably a 20 oz w/ on/off valve and a macro line to run into your intake

and if your a big grower ask any local restaurant or place they have fountain drinks

they always got empties in the back mostly 20lbs throw some cash and there yeah go!

rent em, lease em, buy em. 20 pounders, 50 pounders. Welding shops got em, Fire extinguisher dealers got em, A big Company with lots of stores everywhere in USA called Praxair has a whole lotta em. Prax refills em too, cheap like $12 where I am at.

niiice guys. thx ill check it out...
