Regular Male/Female seed will need to be monitored for the presence of male plants. It is more adventurous because there is no way to know exactly how the plants will express their genotype. These seeds will exhibit different characteristics due to genetic variation, so growers can hunt for the best plant, or the one they like the most, and continue to grow it into the future using cloning. Seeds have several advantages. Plants grown from seed are able to develop a tap root, this is the underground equivalent of the main stem. A strong deep taproot is able to reach the water table or moist layers of penetrable subsoil. The taproot and stem form a single column, so water and nutrients are easily drawn up to the plant canopy.
