In the USA, whats a good way of buying co2? How do you apply it to your grow?

[moneyshotpb]

just be aware that if u r gonna buy commercial CO2 capsules (similar to ones used in restaurants) from your local hardware/wholesale store, they will ask for id and record all information, i think due to a federal law

and if u frequent the place for CO2 without owning a business or doing something legal that requires that much CO2, u will most likely get flagged and reported

not true
