Lots of cloud chasers will vape pure VG. It gives the biggest clouds and has no flavor other than a very feint and light sweetness. It's also incredibly cheap to get quality USP VG. I get mine from Amazon.
Just decarboxylate some concentrate, you can use a strain like good medicine or something similar that is high in CBD. Use a double boiler like this, you put the concentrate into it, let it heat up to 280 degrees and no warmer for about 5-10 minutes, then add your base.
You can use food grade glycerin, or ethyl alcohol. Either will work as a base. So measure your base, if you have 100 ml of glycerin or alcohol, do the math based on the potency chart on the back of your concentrates package.
So if your concentrates are rated for example, at 23% THCa 0%THC 30% CBD then for 1 gram you would end up with a dosage (after decarboxylation) of around 1.9-2.0 mg of THC per ml and 3mg of CBD per ml of Tincture. (THCa is converted to THC by decarboxylation, making it biologically available)
Mine tastes similar to cough syrup without the alcohol burn. Slightly sweet with an odd mouth coating feel. Here is what I've been using.
Those flavoring prices look insanely high - check heartlandvapes.com ( http://wholesale.heartlandvapes.com/watermelon-tfa.html 4 oz of watermelon for 8.50)- I just got 16oz bottles of some TFA fruit flavors for 12-20 bucks from there.
Also, the cost of that VG/PG seems inflated. If you don't mind buying in bulk,
Lastly, I found that once I had a formula down, I wanted to make big (8oz) batches, and I wasn't too concerned with the exact ratio of PG/VG. I prefered to eyeball it, and these dispensing bottles made it much easier.
