BHO=Butane hash oil.
Heres a post I made showing how I do it.
The danger is you’re working with butane and need to eliminate any risk of sparks or a stupid freind trying to light a cigarette or something 
I do my “blasting” outside and I don’t allow anyone near me when i do it though I have someone on standby on the crazy chance something goes wrong. But check out my post, there is way better equipment then what i use but my way works all the same in the end.
