Hi,

im thinking about breeding my own feed as its costing a bit now that i have 5 snakes,the only way my mum will let me/us is if i can use Co2 to kill them.. ive tried to find a homemade instruction set but i havent had any luck.. Im sure there was one on here once upon a time but ive not been able to find it. So far ive tried google and using te search on here, if anyone knows any good searches to use or has built one and wouldnt mind helping me out with some instructions id appreciate it very much.

thanks for reading and the help

Just buy a bottle of welding CO2 from halford and a tap and pipe put them in a dustbin and put the pipe in and turn the tap on doesn't take long
