Flowering

[TheReaper]

I am growing my first few plants outside. These plants came from my mother plant not seed. I noticed yesterday that the plants are starting to bud. Isn't it to early for the plants to start to bud?

Any insight from others that have grown outside?

In Grand Junction,.

Mine have done the same thing, I've had two males show the past few weeks and one I'm keeping a close eye on. I think this weird weather has had something to do with this because we should have another month of vegetative growth left. I'm pulling mine inside at 6 p/m every night so they stay in the flowering mode, I'm afraid of the weird weather causing hermies and my plants are already bigger then I have room for.

I think there is about a 14 1/4 hour daylight period in Denver now. I have found many Idica dominant strains will begin flowering with that. By the middle of September the daylight length is barely over 12 hours. This is less than eight weeks from now. Sounds fine to me.

August 21st is about the trigger date for flowering, light decreases about a minute and a half a day after June 21st.

This would depend on strain and location.

On August 21st in Denver there are 13.5 hours of daylight. By September 21st there are 12 hours and 13 minutes of daylight. Denver can get the first killing freeze as early as the first week of September though usually it holds off until the first week of october.

So if you have a 56 days-to-finish strain, relatively short, I think it would often get freeze-killed early if it started flowering as late as the third week of August if my understanding is correct. I'm a little unsure how the steady shortening of the days affects the days-to-finish though and I could be wrong.

I do know I have pure indica strains that trigger at 15 hours of light outside and Denver never gets a day that long all year so they start immediately. I have Sativas that can't ever finish outside this far north.

I think there are now "autoflowering" strains that don't trigger on day length at all-they just go. They are from the Cannabis Ruderallis family found in Russia recently I think.

Generally speaking August 21st is about the trigger period and yes depending on your longitued and latitude that could vary some. I could be wrong but the closer you get to fall the quicker the days become shorter? My brother lives at about 4800 feet and said the last week of august and the first week of Sept. are the only two weeks of the year he knows he won't get any frost. He has to run a heater in his greenhouse every night into the first week of June.
