Strain
There are 2 reason to wait for curing resin before processing : 1 scientific and the other both scientific and historic. Is scientifically proven than at 12°C glands loses 15% of original size in 6 months. Traditionally kif is drummed in mid September than stored until January when in those mountains temperatures drop to 10/12°C. The cold restricts matter for another 15 %. So the goal is to process and press the resin when it loses about the 30% of size. Here the magic happens. Smaller (but not lighter) glands stick and melt together much better when pressed and because nothing is destroyed but is transformed, the magic of hashish perhaps it resides precisely in that volume that was lost with aging and that turns into something special.

AFGHANI
Typical Afghan hashish is processed using mechanical friction, water or tea and lot of heat but isn't pressed, the melted pasta drips into a mold (500 gr/1Kg), it is simply pached after cooling
LEBANESE
After been crushed kif is roughly hand sieved with tumbling sieves. Jute or cotton bags are filled usually with 200 gr of matured dusty resin and then, 10 or 20 a time, heavily pressed at 7/10 tons.
ONLY PRESSURE
MORROCCAN
Here the final product is processed and packed in two ways: the resin after seasoning is hand kneated often with tea or water, it is given a cylindrical shape, to which the film is wrapped and then softly hand pressed without using forms. This results into dark red/brown soft, sticky and gummy plates. The most common type is made by fulfilling pre-formated plastic bags that after sealing are pressed homogeneously into steel forms usually up to 3 tons. Commercial 100/200 slabs are pressed 5 together often adding some heat getting darker slabs. This results green/golden slabs, less or more hard.
HAND WORKED
PRESSURE
HEAT
Everyone of us is capable to do hand worked sticky hash but if U want to obtain a pollen like chunck that crumbles like flour and on the touch feels like velvet the secret is to press homogeneously by using a metal or wooden form, this us more important than the pressure used.
For physic laws without a form the pressure energy will be dispersed in the sides resulting uneven. Applying the same pressure into a form it will results homogeneous in each point. This let the trichomes melt together and decarb.
