There is a lot of good info here on STB's and Acid/Base extractions.
I know almost nothing about chemistry and started with an A/B extraction. It really sounds complicated until you sit down and realize:
water+vinegar+mimosa
cook 3 hours, remove water/vinegar, add water+vinegar again
repeat for a total of 3 cooks
Add base until very black
add naphtha
remove naphtha
put in freezer.
That's it!
Granted it is a little more involved than that but really it is very simple.
STB's are even simpler, but you may want to do a little research on recrystalization (which honestly is not hard either) as STB crystals can be a tad harsh.
100g is more than enough for a STB. Just remember to use lots of water and a small amount of naphtha (like 100mL pulls).
I'm glad you are learning to extract your own. There is something very rewarding when you are looking a crystals that you extracted from a plant.

I don't know SWIM and personally don't trust him at all. If SWIM is posting, most likely I will not respond...as I said, I don't trust the guy. YOU I trust, but never SWIM.
