As it turns out secomd crop from mature flowered plants is a rather simple step that is worthwhile. I had a decent grow and took 3 plants that I cut back but left about 1 foot of growth instead of pulling and placed them in the dark with no watering for a week. Then placed them in the veggy mode area. It took about 3 weeks for them to develop very nice bush like leafs and didnt appear at all to look like the orginal type of plant. Next i placed them in my flowering area and after 2 weeks they are sprouting buds all over the place. They didn;t shoot up like a normal grow does but simply started to bud. I will measure and report the quality of the grow when they get mature. I read with surprise "here" about a second grow and decided to try it.
I've revegged for mums before, reveggers make great mums for the reason you stated, you're already doing the biggest prune the plant will ever however so you end up with cutting (in the above case bud) sites in abundance. Peace and goodluck brutha reveg. SS
