Are you doing the method where you heat the rosin for a long time?Sounds about right, terps being the best option for dilution for carts. Speaking of which, I am working on my first carts. First up, Meph. 4 Assed Monkey, next up Meph. 24C x Stone's Dragon #1 (black). Remains to be seen whether terps are needed, but I have some on hand.
