I want to try making ISO hash oil but does not grow so cannot obtain trim/leaves. Instead, I will be using about 7gms of regs, 1gm of KB and 1.5gms of decent hash, washed in 70% ISO for about 1 min, filtered and evaporated. The herb will be ground up in a space-case type grinder, not a coffee grinder, if the consistency makes any difference to the yield. Can anyone experienced provide an estimate for how much I will obtain?-(I do not have scales.) Thanks for any help provided.
