Okay, here goes…Start with good weed…duh (I use 120-160 micron sleeve screens to put the puck into):
- Fill the 30 cm mold with 7gm of flower, tamping it down as required;
- use a clamp to squeeze the puck down to about 3/4" (20 mm);
- put the puck into the sleeve, and fold the ends over;
- put it in the press at about 100 PSI (enough pressure so the puck cannot move), and preheat for one minute;
- bring the pressure up to 1000 PSI (slowly keeping pressure), over about 15 seconds;
- maintain the pressure (it will drop) for the required amount of time (usually 3 minutes);
- at the end, raise the pressure to 2500 PSI (I go max on this 6-ton) for 30 seconds;
- release the pressure, and remove the parchment, puck, and rosin from the press;
- remove the puck, and let the rosin cool for a minute or so; and
- gather and store the rosin.
In my rosin thread below are some pictures of how to make pucks. If you don’t have a mold it’s easy to fill a sleeve by hand and mold it into a round-ish form. It takes a little practice, but not hard.

Rosin and puck THC Content I found three studies that should shed some light. High Times - They looked at all the THC tests of 3 years of Cannabis Cup rosin entries in 2014, 15, 16. They came up with a an average of 76% total THC in the rosin. Extractioneering tested 60 samples of rosin...
