I've read through most of the other threads concerning concentrate juice. They all seem to be geared towards high-viscosity liquids using vape tanks. I've used these and I think they're great, but right now I'm interested in making a thick, potent mixture. I'm using the glass babyton atomizers that most vendors are using with their prefilled vapes. The issue is that I end up having to use a 1:2 terpene to concentrate ratio before they actually start to produce vapor out of these cartridges, and at this point the flavor and high of the mixture is just overpowered by the terpenes. The other day we were able to refill a Pax ERA cartridge which is a prefilled concentrate pen. We were able to fill it with a thick liquid of 1:5 ratio which ripped extremely well. The taste was mostly rosin with a hint of terpenes and was exactly what I've been looking for this whole time. Unfortunately I can't source these cartridges empty. My question is if anyone is using thick mixtures with low ratios of terpenes, and if so what cartridges are allowing you to accomplish them?
