finally a real answer!! ive been looking on google for 30 minutes and nobody had the answer i was looking for! did you just use the leaves? you didn't grind up any stemers?
In that case I just used the leaves. Stems would work fine I think, if you could grind them up into small enough bits.
The challenge is that this is a far smaller ratio of THC to oil than regular pot brownies, made with actual bud. So the more plant matter, the more oil you're going to need to cook it in. This means you end up having to consume several times the amount of oil typical for a dose with pot brownies. I had to eat an entire half batch to get my trip.
So I guess my approach was to use the strongest part of the plant (relatively speaking), which was the leaves. The extra oil I would have had to consume to get a little THC from the stems might have been unpleasant.
I already had a half batch of brownies made just with oil, no egg, no water, and it was super moist and almost more brownie that one wants to eat at one sitting.
So you see, the more parts you use, the less efficient. It's up to you. If you can drink a solid cup of lawn flavored vegetable oil or eat an entire pan of brownies, then you won't have any problems.
I decided to use the stems to make Green Dragon with some 100 proof vodka. Ahh, feels good to be using every part of the buffalo.
Here I am once again making a compromise by not completely sacrificing taste with Everclear, a more powerful extractor of THC.
