I cant take it any more...Ive been lurking all winter, but I cant take it any more....this is too important too pass up, and now the discussion has gone past my understanding...Plus I feel I MUST share my experiences.
I too have been plagued by early flowering clones, some years it has made my whole season a bust...Came to realize that this issue is EXTREEMLY IMPORTANT, and only gets more sensitive when you use early outdoor style strains, like I do. you know, photosensitive strains, those trigger early every time for me..
Last year, I started my seeds on 15/9(indoors, January....see grow thread, link in signature)....They preflowered a fiew weeks later, I culled the males, and kept the mother plants in the same 15/9 photoperiod. Took clones mid may, transplanted outdoors early June, with no early flowering...The clones stayed in vegetative state through the transplant phase due to the fact that I matched the hours of light to the day of transplant...As far as photoperiod, the plant doesent know weather its inside under a MH, or outside on june 5th, ya know...
15/9 vs 24/0:
Silverback, I agree with yer statement in the sluggish growth of a 15/9 lightschedule...It took noticibly longer to grow and root my outdoor moms, and clones, as versus when I do indoor runs under 24/0...After having so many different experiences with this early flower tendency, im waaaaay too scared to chance a crop of clones rooted under 24, and transfered to 15...My past experirnces have led me to believe that they will guaranteed flower, indoor, outdoor, or green house, ,,,,go from a 24/0 mother, and transfer her clones down to 15/9 and there gonna bloom(or at least start to), no doubt about it,,,,Just because you cut the branch off the mother plant doesent mean you automaticly erase its memory.
..Specially with the indica doms, and the earlys.....now maby the more sativa plants, are a different story....Every year, back when I was trying the 24/0 thing with my cutts, the sativa dominant plants would transfer photoperiods just fine..
This year I am doing a test....I have alot of new strains that are curently under 24/0 from trades, and my winter indoor run....I am dying to try these outside, so im gonna attempt to simply throw these cuts in my 15/9 room with all my seedlings. I am expecting them to start growing more slowly, and start preflowering heavy, for roughly 2-3weeks.(same as they would if I tried to plant em outside on May 20th)...Next, im hoping they will slowly start to reveg, and fall in synch with the new photoperiod. I will veg them out, and clone off them along with my other mothers.. I am trying to make up for the slow growth during the 15/9photoperiod, in volume, heavy co2 enrichment, and an early start indoors...
Butte, You made refrence to light intensity, and its correlation too holding a plant in veg...I have a thought on this....In previous years, ive started plants under shoplights, just simple floro's...really weak light. They stayed in veg for quite a wile, and transfered to the guerilla patch just fine....Out there in cali, yall get some nice sun, so it really shouldnt have mattered weather you had em in trees or not, that sun was alot more intense than my shoplights..I cant understand why your clones bloomed on you
Can you expound on your theory.
Only ways I know to work with/around early flowering in outdoor clone transplants:
-Plant seed directly into the outdoor patch.
-Veg large plants indoor, all summer, an put them out in the fall, to bloom.
-Start seedlings or clones early in a cold frame, hot house, or green house, with artificial light.
-15/9 from start with motherplants.
-Plant very sativa dominant strains
-bring in plants at night to a lit shed, barn, ware house, or garage..

I am very glad this issue is being discussed, it is in my eyes one of the most important factors in outdoor growing with clones, goes hand in hand with strain selection...
A week or two after the transplant, and veggin away. Sweet Purple..
