which method?
were you planing on making BHO first? or Extracting the pictured material with cold acetone? If you were planning on extracting with cold acetone, why are you asking about “14 days”?!?
“Put on lid and wait 14 days” is from the “alternative method”, and you should go look at Only The Strong sauce tek - #103 by Dustin if your plan is to go that route.
Assuming that’s 20g of high-test in the picture, you’re going to get about 4g of extract. pulling most of the solvent off 4g of extract is going to leave you with about a teaspoon full… if you follow the protocol and do it in a rotovap, it will all be stuck inside the boiling flask.
You could certainly evaporate your 100ml or so of solvent in a glass petri dish or other shallow container, you might then be able to achieve crystals in a 10-15ml test tube.
