Howdy !!!
I knew folks who took clones of flowering plants, grew clone to harvest...no veg period, just grew out the cloned bud...(they came around every august with a dixie cup and a rooted cutting for the southern window sill)
it would kinda cool to see a little matrix of colas, all under HPS and fed thru hydro....I have considered doing the same with my winter grow...sog-style...
as far as the clones from seedlings, mothers, or reveg ??? I have seen em all, and all work fine...some strains go hermie from the stress of a regeneration, but can be saved with a couple applications of a dose of REVERSE...
I have also heard it a "best idea" to clone directly from seedlings before sexing, sex the mom and go from there selecting the female clones...I find that a bit too much and just sex the seedlings and clone from there...I think, keeping Mums in veg box forever is a very good thing, taking cuttings and/or replacing as needed...
