How do I regenerate/rejuvenate/reveg a plant after harvest?How do I regenerate/rejuvenate/reveg a plant after harvest? After the buds are harvested, you may realize just how much you want to perpetuate a plant you neglected to take cuttings from. Cut the main stalk down to the point where below several growth tips or buds are remaining. Return the plant to a vegetative fertilizer and 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 products containing ammonium form nitrogen, such as chicken manure or Genesis Formula Grow 2 will encourage rapid growth and stem elongation. Trace element supplemenation, co2 and 24 hour lighting are helpful.
