I was thinking of making some ISO or BHO oil. From what I have seen the BHO comes out a golden brown while the ISO come out black. Is this normally how it is? Also I've seen a lot of people say never use ISO because it is dangerous. Is this true? Do you just need a really high alcohol %. Do you need to get it bone dry to not be dangerous to your health? If I do either method I will use the highest quality of either one. The best ISO I can find is 91% around here. And for BHO I would have to order high quality multi-refined stuff online.
