I did several things. I made 151 GD (GTGD using the method linked) then I tried to transfer the GTGD into a 50/50 VG/PG mix and reduce the alcohol and water out but that failed miserably.
The second GTEL experimental batch was just soaking a volume of ground material in VG/PG for several months. That's the one I've been testing for 2 days. I can't say that I'm impressed with the potency; the GTGD came out better. I'll add pictures though.
I think I started with a gram or two in a 15-ml e-liquid bottle with VG/PG covering the material.
I cut the top off to make it easier to strain.
About 7-ml of GTEL#2 ready to be bottled.
Done.
Dry dripper.
Wet dripper.
Taste is only fair and I even added a couple of drops of Cappella flavoring to it; the aftertaste kind of reminds me of dry Captain Crunch cereal. Potency - lacking in the amount that I vape. I need to further concentrate it, imho.
