Auto strains can start flowering within a couple weeks of sprouting from the seed. Some regular photo period strains start flowering at anything less than 16 hours of light. Most strains flower at anything less than 14 hours of light, which is about now for outdoors. If you're asking when is the earliest a plant can flower after sprouting from seed, I think the average is about 6 weeks. If you're asking when in the season is the earliest, some plants start flowering in July like my purple diesel. It's nearly halfway finished already. Most strains won't flower until sometime in August, depending on strain. And most will finish in October. I hope something in this comment helps you.
Depends on the strain but 7 - 8 weeks minimum would be a good place to start thinking for a photo period plant
it takes 1 month for a plant to become genetically mature from seed, so given a 1 week grave period for the switch, 4-5 is really the minimum for a photoperiod
[quote name='"ptsd420"']What about from cutting? How long till switch? BRING THE BUDS TO NORTH CAROLINA![/quote] Dude google this shit or at least search the thread. Cuts are as older as the mother, theyd are clones this should be obvious. They can flower after theyd root
No need to be rude and by the way your english is horrible. But thanks for the help and for being a prick. BRING THE BUDS TO NORTH CAROLINA!
