Hey guys, finally a cost effective way to supply Co2 to your room without monitoring, no open flames or dangerous propain tanks or co2 tanks. Found this in Cannibus Culture April Edition i was just reading. Check it out.. Pump and 1 bucket (supplies co2 for 60 days) is 125 bucks, new replacement buckets is 100 bucks, dont know if you ever used Co2 Tanks but it cost alot more refilling Co2 tanks for 60 days supply. Here is a pic of the product ( http://www.co2boost.com )
