hehe yeah the high is great. the taste is nice but the high is very strong and lasts way longer (for me) than with normal hash.
i think BHO (butane) and ISO (isopropanol) are about the same quality, to be honest i dont know the difference between BHO and ISO-oil except for the method of extraction
Ive made some butane honey oil yesterday (and today)
ive used a pipe, some screen, tape, 500ml gas, a piece of iron in which the gas goes and of course the trim..
put the screen on the pipe, put the trim in there, put the iron thingy on top of it and put the gas down there.
the cannabinoids will come down with the gas, into a container. the gas boils at 0C, so after some time only the oil will be left in the container.
I have had some problems (the trim was too tight and didnt let the gas through in the end) but i managed to get some fine quality BHO from trimmings only.
