Dry sifting method is considered the lower hazardous & lesser labor intensive method of extracting the THC from marijuana cannabis plants. Additional strategy’s embody using either butane(very dangerous explosive), wet methods with water & ice(very time consuming). The humble technique to distinguish the resinous THC from your affectionate practice of growing your annual is dry sifting  (ie: removing the THC resinous pistols from your trimmings, twigs or anything with resin remaining on it) either with a manual sifting screen or a automatic sifting machine.

Very important prior to dry sifting your plant matter:

1. Your cannabis must be cured / dried before processing. The purpose of drying is to harden the resins from your plant so they do not accumulate & stick to your sifting screens, they do not gum-up the filters! Besides this makes for better extraction overall, even for BHO (Butane Honey Oil) or wet ice methods. Drying is only removing the water content remaining  in the resinous pistols & leaves, it does reduce the THC.

2. Freezing! The freezing of your gear anterior to dry sifting is very significant. Freezing for a much easier / integral extraction, so that the resinous gum break freely from the leaves & twigs. Though sifting your substance de-freezes consequently the gums will not break away easily. It is suggested to refreeze every 20 or 30 minutes to restart the process until complete extraction. If you have a large bag of cultivate to process reserve it in the freezer & do smaller doses at a time. The portions that you have started with, replace into the freezer in a different bag, so you may know what you have already dry sifted once or twice.If possible, obtain a mechanical dry sifting machine that can fit into the freezer, this avoids the refreezing process & you can exact continually until you retain all the resinous THC gums.
