I was thinking of buying in it and leaving it in my room for if I ever want to do it. So I don't have to go out and buy it or fill it. But idk how long the gast will last in the tank. I appreciate if anyone has any input

Many years--I've had mine for three years, PSI has only dropped from 2200 to 1550(still enough to kill me 10 times over) in that time, its best to get a large tank, mine is 125 cu ft, 3500 liters

The one I can afford is 1 cubic meter, but I am really bad at math, I was just hoping it was enough

A friend had one for a few years and it depleted. You can always refill them. The tank, not the gas, costs $. For example, if the tank with gas is $100, then the gas alone is like $30. At least where I live. If they ask why you are refilling it, just say "my uncle preserves peaches and apricots and he asked me to fill it for him."
