I made a batch of tincture using two cups of Everclear and a zip of some HSO Blue Dream that I had. I used this strain because though the plant was a massive producer(~ 7 ounces from one plant in 3 gallon smart pot of soil) it turned out smelling and tasting like almost nothing and had a mild potency, though I'll reserve my judgment on the strain as a whole until I grow it again.
I decarbed the herb(whole buds) at 245F for a hour in my oven using a remote oven probe to make sure it didn't fluctuate much or go out of range. I wrapped it up in aluminum foil so the herb and probe was totally contained.
I took the decarbed bud and added the two cups of Everclear to the Magic Butter machine and set it to 130F for eight hours overnight. I then put it on for an additional two hours at 160F in the morning. It filtered out easily through the included bag into a 1000ml beaker. I had about 420ml of super dark green and slightly brown liquid. I reduced this to about 200ml by submerging the beaker in a pot half full of water and simmering it at roughly 175F. This was enough for 6 and a half 1 ounce amber dropper bottles.
Just tried it, one dropper full(~ 1 ml) at first, then another dropper full 45 minutes later. It seems like two droppers is enough to give me a decent baseline buzz! So, I'm pretty satisfied with this initial run of the MB machine!
