I use 2.5ml as the baseline only because I recently ordered a small 2.5ml canna-juice bottle from medibuds (few drips on my RDA and I'm ripped--highly recommend). As making my own is likely cheaper and not too difficult, I thought I'd give it a try. My question is how much juice I can expect to make (concentrate+EJmix) per ml/gram of either shatter, wax, or hash oil?
Depends on how concentrated you want the solution to be.It's easier if you know the aprox. THC concentration of whatever you end up using.Substract a few % of the final product,cause most likely you're not gonna manage to get 100% of the THC out of whatever you end up using.
