Hi ! I'm into concentrates for a couple months, I prefer that now.. cause of the intense high you can get with 2-3 single drop. I use 99% ISO with nice buds.. always gave nice results. I just have some questions for you! Or just give tips/opinions about oil Using hot knives or a nail with oil is vaporizing? I think it is, cause my bong stay clean You think it's safe even after the alcool evaporate? Any alcool remains in the product ? Should I use 94% comestible alcool ? Just not sure about the safety of that.. same for bho! I've seen that when you got your iso oil ready(pic1), you heat it on the stove to get it melting.. and supposed to give a better product, I tried it(pic2).. lot of bubbles in it.. what's about that technique? I was reading about budder.. lol Oil is the better medecine I've tried. Just concerned about the risks of it ! Maybe make hash with water/ice is a better choice. Just give your toughts! Thank's!
