After a seedling has been grown to maturity and the buds are harvested, you may realize you want to perpetuate a plant you neglected to take cuttings from. Cut the main stalk down to the point where below which several growth tips or buds are remaining. Return the plant to a vegetative fertilizer and constant photoperiod. Over the next several weeks, the plant will elongate and devlop new upward growth. It is very important not to overwater the plant after it has been cut back. The reduced above ground plant structure is still being fed by the entire existing root system, which can cause an excessive amount of water uptake and the resultant stress associated. The use of fertilizers containing some ammonium form nitrogen, such as chicken manure or Genesis Grow 2 will encourage rapid growth and stem elongation. Trace element supplements, co2 and strong light are helpful.
