Wow Sakkadelic, that wooden plunger seems very rigid stuff :shock: , no wonder you got good results. And that metal mesh seems so fine that it acts like a cotton bag (to put the seeds in). Though I would still favor an extra muslin bag (or a fine cotton sheet) during squeezing.

I agree, there's really no use to filter the very first based liquid. Even more: better to do some A/B transitions before the first filtering of acid liquid takes place, how much A/B's depends on the clear-ness of the liquid showing. Once you have filtered in acid stage, the next filtering of base will be a piece of cake no doubt.

Jayrocco, 5.4% is neat for whole seeds :thumb_up:

We must also not forget that % yield is not solely a factor of extraction technique, the potency of used seeds is mandatory, and can vary even greatly. Therefore when comparing workflow/yield one should actually use same batch seeds, something I was able of comparing the grind-workflow vs. squeezed-whole-seeds.

Thus so far we have 3 potent (combined) candidates for success, Sakkadelic tek

- freeze/thaw, say 2 times;

- microwaves in the process (thx Nitegazer);

- squeezing them seeds hard before re-boiling.
