You can shake the kif from the stems, but man, you need a ton of them, and the kif really isn't that great either.

Last time I tried, I took about 14g's of stems (I'm guessing), shook the kif, and I barely got 2 pipe rips from it, so to make any sort of hash (pressed kif) you are looking at needing at least 150-200 g's of stems. That's a lot man.

You get a little more out of it making oil with stems though. I made some last night from again, about 14g's of stems and shake, and got almost a gram vial out of it, and it is much more potent than just shaking the kif off. I used Iso and that ensures you get every last bit of THC.

So yeah, you need a ton of stems for hash, and making the oil is only worth it if you got a lot.

Seeds though, contain 0 THC. The only kind of THC on them would just be on the layer from being inside of the bud, but other than that, plant a seed and get a much better reward.

This thread reminds me of that Commander Cody song called "Down to Seeds and Stems Again"
