I'm gonna start making my own carts (💪😼💉). I wanna do a blend of HHC h4cbd. I know those are pretty thick, so what should I use to thin it out?

I want to add terpenes (1ml) to 5g of HHC 5g of h4cbd and add it to my fixed voltage cart and my adjustable voltage carts.

would I need to add something like CBC? I don't wanna break the bank, this is kind of a big investment for us.

is there one c-noid that's decently relaxing and will thin out the blend enough to use in refillable carts? I like CBC, but it can make me a little anxious. I can usually smoke CBD flower, but I'd like my friends to hit it and to be able to hit it on the go.

thank you all :3!!!
