The reason I don’t like bho in cartridges is many folds. Not just one.
First, your gonna need a dilutant and in a much higher % using shatter then using distillate. This decreases the medicinal benefits I can get from a bho cartridge
Second. Most bho isn’t properly dewaxed. So your either gonna have dark cartridges after a little while from burnt waxes or your gonna have clogging issues.
Third. Bho isn’t typically decarbed all the way either. Even if your heating to put terpenes in the mixture. This usually creates flow problems.
Finally. Usually bho is a lower potency than distillate. I’m using all this for medicine. Not for money making. I personally what the highest % of thc/cbd without a malfunctioning cartridge.
Hope this answers why I use distillate rather than bho when cartridge making. If you all want to make cartridges with unwinterized, not decarbed bho, by all means go for it. Im not hear to say what is good and what is bad. Im hear just sharing experiences I’ve had in the past.
