made some for first time top stuff dont know why dint do it years ago .very easy to do the only problem i have is getting hold of the butane .had to go into 5 different shops to get six cans most of the shops would not sell me more than 1 can at a time .never had this much trouble getting it in the early 80s when i sniffed it .just where is the best place to get a lot of good butane, have a lot of leaf that i been saving for years so need it .can i use the gas that is used on them small camping stoves .i love this stuff made from leaf i used to put in the compost yum yum

Have a search online, there are a few places that will send you a box at wholesale prices.

Here you go buddy:-Newport Gas-Zero Impurity This and London Gas is the only stuff I'll use as its near Zero Impurity,remember you smoke this stuff so I wouldn't bother with Swan etc to many impuritys in them..

Colibri is also a good clean source of butane from what information I can gather.

H.T.

Yup this another good Gas for BHO ive never used it,but it is near Zero Impurity
