Even a big tank will only last you three weeks in your size room regrets----The tanks just don't last that long when juicing rooms over the size of closets or cabinet grows and the cost will be about $1.00 /pound---propane will run you 1/3 the cost of canned juice and natural gas will even be a little cheaper than that.
I dont know how you figure it would only last 3 weeks, a 20 lb tank would last 3 months, I dont know how much c02 you give your plants but it can be toxic if you give too much.
