Re-veg (re-vegetation) is reversing flowering in a photoperiod plant by restoring long days, usually 18 h or more of light. Left with some buds and leaves after harvest, the plant gradually stops flowering and produces new vegetative shoots, which can then be cloned or grown on.
In practice
Breeders and pheno hunters use re-veg to keep a plant they only identified as a keeper after smoking it. Leave the lower branches with some green leaves and small buds, keep the plant under 24/0 or 18/6, feed lightly, and wait. Expect 2-6 weeks of odd growth: rounded, single-blade or smooth-edged leaves before normal leaves return. Success varies; old, heavily stripped or very late plants often fail.
Accidental re-veg outdoors happens when a plant that started flowering early in spring sees lengthening days.
Don't confuse with
- Monster cropping: rooting cuttings from a flowering plant; the cuttings re-veg.
- Cloning before flower: the easier route; keeping cuts of every candidate avoids needing re-veg.
The daily length of light versus dark; photoperiod cannabis flowers when nights grow long enough, rather than at a fixed age.In grower slang, a pheno is one individual plant from a seed lot, usually numbered during a hunt, as in "the #4 pheno".24/0 means lights on 24 hours a day with no dark period; GenetixBay endorses it for veg, as cannabis does not need a sleep period before flowering.18/6 is the standard vegetative light schedule: 18 hours of light and 6 hours of darkness each day, keeping photoperiod cannabis from flowering.Monster cropping is taking cuttings from a plant in flower and re-vegging them, which tends to produce bushy plants with many tops after an initial slow phase.Cloning is propagating a plant by rooting cuttings from it, producing new plants that are genetically identical to the donor.The flip is switching a photoperiod plant from long vegetative days to a flowering light schedule, usually around 12 hours of light, to start flowering.A mother plant is a female kept permanently in vegetative growth to supply cuttings, so a selected genotype can be propagated as clones indefinitely.
