So, this was not done by me, it was done by ecodyst in house. 15lbs batches with 15 gal. Reused 10 times. I maxed out at 30lbs/5gal. Gonna try for 50lbs/5 gal once i get more material to confirm this though. Key here though, is doing it at room temp. It can’t be done at cryo temps, solubility is to low.
Edit: i do know that you can get 1g/10ml in etho cause I’ve dissolved that amount of bho in etho before. That means you can get around 1850g/5 gal which means that my average yields of putting 15lbs material/ 5 gal only gives me 400-600g/5 gal which is only a quarter to a third of its capacity.
