a revegged plant has gone Veg - Flower Veg - Flower
Does not seem to be any visible or smokeable difference in the finished plant or bud compared to standard , the seed/clone variation is often quite obvious dependant on cultivar.
From what have personally seen , there is no accumulation of problems due to repeated revegging , have reflowered several disparate plants up to four times with no issues , seems a period of flower or veg of sufficient time will erase previous hormones like a reboot and previous history is then irrelevant.
Behaviour dureing reveg has proved a usefull extra selection tool , many individuals of both sexes will express intersex traits to some degree and the worst culled or flagged as a non breeder.
