The bottom line: this XL bag delivers a steady, maintenance free supply of \u003cstrong\u003eCO2 for grow tents\u003c\/strong\u003e without heat or electricity, and because it is over twice the size of the regular bag it is intended for medium to large grow spaces where a single bag needs to cover more volume.
