cesarhorta Reviewed by cesarhorta on . seed selection for good breeding Seed Selection Nearly every cultivated Cannabis plant, no matter what its future, began as a germinating seed; and nearly all Cannabis cultivators, no matter what their intention, start with seeds that are gifts from a fellow cultivator or extracted from imported shipments of marijuana. Very little true control can be exercised in seed selection unless the cultivator travels to select growing plants with favorable characteristics and personally pollinate them. This is not possible for most Rating: 5
