You have a very good idea here, but I think the black box phase where you control their light exposure will need to continue long past the initial flowering onset and should probably only stop once the natural length of the day is roughly 12/12.
You are going to get some absolutely insane bud structures from these reveged plants once they start flowering again. They will be like big pom pom hydra buds.
Given that my grow this year is largely an experiment, I'm looking forward to next year, trying to decide what exactly the experiment taught me this year, and what I should change next year to make the grow more successful.
We are basically on the same page in terms of the need to continue black-boxing the plants longer next year. But I'm not sold on your suggestion that I continue until the natural day/night cycle reaches 12/12.
Trouble is, the natural day and night length doesn't reach 12/12 until after the fall equinox in late October - later if you count the extra hour of twilight added by dawn and dusk.
I don't claim to be any sort of expert, but I've done a great deal of reading on the subject. I'm not certain that a 12 hour day/night length works magic outdoors like it does indoors. Several writers (mostly posters here at ICMag) have suggested that the triggers to start cannabis into flower and keep it there are substantially different outdoors. Outdoors, the plants are sensing many more parameters, like natural changes in sunlight color as fall approaches, day/night temperature fluctuations, and probably some other elements of the plant's atmosphere that we don't realize are playing a role in triggering flowering.
A simple 12/12 light schedule can't be the trigger for flowering outdoors, since the day length now is still well over 13 hours (when twilight is included.) And yet, all of the cannabis plants in my garden, both Sativa and Indica, have already been in flower for a week or two - naturally.
We share the inclination to simply extend the black-boxing next year for a longer time. While it may not be a complete answer to the theoretical questions in my mind, it IS at least, the one parameter that we can control most easily. It just keeps me at home for more evenings.
You're sure correct about the pom-pom look to the colas that are now re-vegging: they are already getting huge (and heavy!) I'm planning to build a cage around Zamaldelica today, and then remove the greenhouse structure once all her branches are well-supported. Those growing pom-poms are getting heavy, as well as huge.
