From a budget standpoint on each garden usin an extra hr of 1000`s of watts per lights on cycle regardless if you lose it lights off during the bloom cycle , has always been the debate .........and ...........
It`s not worth it from everyone I`ve ever seen trying to manipulate photoperiods, and there`s never been any solid info on phenotypic traits be they Indica or sativa , as well as all the gozillion polyhybrids that`re bein run these days........
DJ Short`s touching on each end of the spectrum A-Z , but shit we`ve ve run for the last 15 yrs or so are strict polyhybrids and so mixed up with God knows what there`s no wayta say which photoperiod is best......
I always used 18/6 for preveg and cuts , and 12/12 for production.....I tried 24/0 and found it slowed the girls down IME for the babies rootin....and......
Fuck Bubba Kush for production unless yas got a clone factory pumpin out budsicles on mega cut flood tables or vert Bobble racks.......but.....
That shit`s good meds.....Coffee and hash taste with killer arthritis and insomnia therapy....
My kinda shit......fer meds.....not production......
Peace....Freds............
the amount of daylight effects hormone production. The less light, the more hormones and the faster the plant finishes. So, if you have a heavy indica, say afgooey, and you flower it under 13hs of light, it's going to stretch more than it would under a 12 hour light schedule... but the final maturation date is delayed.
If you want to run an indica, flowering under 13hs of light the first 2-4 weeks, you'll get the plants the stretch... but it's just easier to use a hybrid that stretches on it's own and produces nice big buds.
For more Indica dominant hybrids that might help with stretch and growth before and after the flip Bobbles .......but......I think running flip rooms you could do 4.5 week 13hs and 4.5 weeks 11hs... and you could potentially get the desired results... with the same total energy consumption. Maybe one day I'll be setup to where I can do a side by side... The only way to prove it is to do the research, since it doesn't exist.
