I’m looking at those things you have as well as rosin presses haven’t fully committed to one yet.
What’s your process once you chop to get end product? Do you have a vacuum oven?
With the rosin you dont have to sift, unless your goal is to press kief only and I’m not sure why one would dot that to be honest?
One method is to dry, cure, press then take the pressed flower and do the QWET to draw the last bit out.
Another method is to freeze it and bubble hash it, this is best done with dry ice though which is fairly cheap and readily available.
From what I have read doing the QWET is also best done with dry ice.
So it’s all a process if you want good quality concentrate I Geuss.
But yeah what’s your process once you have chopped?
