Step One: Stop fertilization one or two weeks prior to harvest. Latent nutrient accumulation on foliage imparts a fertilizer-like taste when you smoke the weed. Leach nutrients from the growing medium a week before you harvest. ** You can continue to fertilize up until three days before harvest if using a product like final flush. Such products expedite flushing built up chemicals in cannabis plants. Some of the flushes even come with flavors such as pina-colada, raspberry. ** Step Two: Mist plants heavily to wash off undesirable residues that may have accumulated on the foliage. The bath with not affect resin production. Wash the garden early in the day to allow excess water on leaves to dry before nightfall to prevent fungus and bud blight. If bud mold is a threat DO NOT WASH BUDS. Step Three: Harvest entire plant or one branch at a time by cutting near the base with pruners. Jerking the root ball creates a mess and is unnecessary. All of the THC is produced in the foliage. Some people that grow marijuana separate the root system from the growing medium at this point.
