CO2 Advance system in a 60-P ?
 

How long one cylinder of CO2 advance system would lasts in a 60-P at 2 bps ?

And just curious why is there a big difference between the cost of the same product ?

I am using this on my 60p. First it would depend on how many plants you have in there but at 2 bps I would say 1 1/2 months to 2 1/2 or at 3 bps I would say 1 to 1 1/2 month at 4 I would say maybe a month this is about how long they last for me not sure what other people are getting

What ADAtank has said is fairly accurate for the longevity of each cartridge in a 60-P.
