Cannabis seeds, flowers, buds or plant materials that have been frozen immediately at a very low temperature after being cut are called Fresh Frozen. For best results, most cannabis growers remove the fan leaves from the cannabis plant because they do not contain trichomes. They also use only small buds for the fresh frozen process. This process helps maintain the cannabinoid and terpene content of the living plant.
Fresh frozen cannabis plant material is used to create high-quality BHO. It is also the name of a certain type of hashish created only from fresh frozen cannabis buds and trims. The process involved in fresh freezing is beneficial as the plant material is not crumbled and dried as is generally in the case after harvesting cannabis.
