I wonder however if I'm leaving THC behind. Has anyone sampled gd from a 2nd soaking to check its potency? If anyone knows if a 2nd soaking increases yield, can you please let me know how you do this (times, temp, volume of everclear, etc...). Thanks!!
I do a second extraction, but I've never actually tested if it made a difference. I just always suspect that there is some THC left behind, and I want to get it. If you think about it, if you are only making 1 ounce of GD with 1/8 oz of weed, then the doses are pretty strong --- maybe just 1 or 2 mls for a dose. There's no way to squeeze all the liquid out of the bud, so there is probably a few mls left behind just with GD still absorbed in the weed residue.

After you do the first extraction, save the GD you have extracted in a separate container and put the squeezed-out weed residue back in the cup that you used for heating. Add in more Everclear. If you used an ounce the first time, maybe use an ounce the second time. (I always use a couple of ounces the first time and a couple the second time. But I don't make a super-concentrated tincture. I like mine to be dissolved in more liquor, so it doesn't matter if the amount of alcohol is a lot higher during the extraction.)

I generally use the heated water bath for the second extraction but not as long, maybe 5 mins. If there is any sticky residue left in the cup, especially if there is a ring of residue from the boiling, be sure to use a spoon to wash that down into the liquid and get it disolved --- there is alot of THC in that stuff that will just stay stuck to the cup if you don't get it dissolved. Then extract the second "squeezing" and add it to the first.

Even though you probably capture more THC, if the end volume is now twice what you had with one extraction, then the concetration is probably close to half --- you'll need to about double the dose to get it right.

Good luck and let us know how it goes!
