Thats how I keep mine 3-4 years.Sometimes I won't even take cuttings... Reveg then flower and back to reveg. Never ending cycle. I've never had one lose vigor.. They even produce more than the first flowering at times or the same.. Never been less. But I use a 10/14 flowering schedule. And since I changed from 12/12.. They have all been better producing. The trick to the reveg is trimming the rootball and transplanting the day of harvest. Go on and get all the stress outta the way at one time. Instead of stressing it several times.
