DRYING AND PRESERVATION OF MARIJUANA

Drying is for that decarboxylation of THCA (tetrahydrocannabinol acid, no psycho-active) is transformed into THC (Delta-9-tetrahydrocannabinol, psycho-active) and oxidation of the THC becomes CBN (cannabinol, 10% of psycho -THC activity) that the latter gives a more relaxing.

Many growers believe that hanging floral clusters upside down for drying resins causes gravity to move the limbs, as with other superstitions, little or no resin or cannabinoids are transported through the vascular system after the plant is harvested . Investing for drying plants, causes the leaves to hang very close to the flower clusters as they dry, and resins are protected from external manipulation of any kind. The clusters also seem more attractive and larger if they are hung.

Resins are very fragile and fall out of the cups to be shaking the plant. The less you handle the bunches will look better and better flavor and aroma to the smoke. The clusters, including stems and large leaves are commonly dried to reach 25% of their original fresh weight (you have to lose 75% of its weight in water). When they are dry enough to be stored without the threat of mold, the central stem of the flower cluster will break easily when bent, like other secondary and stems.

Drying must be done slowly, without light and in a dry and cool, with temperatures around 18 º to 22 º C, reaching a peak. The wrapping in newspaper facilitate drying and provide no strange taste, as they facilitate the absorption of moisture from within and their removal from the outside, but if you have a good dryer not require any accessory
