You would be surprised. Typically, if you extract more than about 50% of the potential using dry sieve, you start to green out from plant debris.That’s kinda like I make my tincture. There are some good tips about keeping the plant matter out of the tincture tho that I will use next time I make it. I defiantly let it hang out in the jar too long. I don’t think I’ll be using the leftovers still. I think I got all the goodness out of it. If our daughter was still making edibles regular I would save it but I can’t see it being worth much to me at this point. so it’s sitting in a bucket in the garage ready for me to get yelled at for leaving it there.
You might consider extracting a small amount of the spent material to see.
