If you are using quality concentrate i wouldnt worry about adding more terps. 25% quality concentrate with a nice flavor and should be fine to do up to a 5% terp mixture. Especially if you are doing a 50/50 CDT botanical terp run. I personally am a fan of a natural wax taste mixing with a super fruity terp flavor, like terps from from Denver Terp. Their terps taste like straight candy and I am a huge fan of the flavor when you mix gassy sunset Sherbert wax with a forbidden fruit terp that tastes like lifesavers. The wax flavor blends REALLYY well with a botanical flavor. Its like taking a soda and making a really nicely crafted mixed drink, it tastes like a soda / uice but has a stronger flavor to balance it out and complement it.
If you are using dull flavored CrC slab then you will definitely get more of the botanical flavor. But since you are using a blend of CDT and BDT you would get more of a terpy flavor.
Honestly mixing wax in with carts is where it’s at! There’s very few ways to differentiate a distillate cart besides terps added. Adding wax adds a whole layer of depth to the flavor of the cart and can drastically change the way the cart hits and effects felt.
I had a bubble issue until i started adding more terps. Thats kinda why i am pro more terp. Adding 1-2% can have drastic effects on consistency. One of my first batches of ax carts had 7-9% and had a good flavor but leaked right outta the cart. But if you bump your terp concentration up to 5% i really think you will have a noticeable difference in consistency.
If you are running wax carts its adament you tell the customer to preheat the device before hitting. Adding wax should make the melting point decrease by a few degreees. It may be more firm at room temp, but once it gets warm it should be more runny than a pure disty cart!
Like i said, my best experience for a wax cart is in a metal atomizer. This seems to give the best rip and also allows for the bubble to flow easier if heated. Ceramic carts are like the d8 of carts imo. More efficient, lighter effects but not like the real deal! But i will say a wax cart looks much more sexier and dressed up in a ceramic cartridge! really brings out all the colors in it.
