So I did one bho run in a glass tube, everything went fine, and I left flowers in tube for a day or so and did it again and got more oil, is this oil bad? Full of impurities? Why does this happen? It ran clear the first time...
YEAH, more likely than not, the second time around you pulled a ton of extra waxes, terpines, etc. with it. It will probably be darker in color. There is totally nothing wrong with it. one could argue the bho itself taints it (i dont), it would work great. in fact, i usually use that batch for my gentlemans vape (Gentleman's Brand Vaporizers) for dabs, because its usually waxier and thicker than the first batch which is usually just thin oil. hope it helps.
