Flowering in spring

Hey, does anyone know how late into the year you can put your plants out, and still have them flower successfully. Last year I put them out in the beginning of march, and they finished fine. I know the spring equinox is March 21st.

Im thinking of doing some outdoor plants right now, would they instantly start flowering? Or would they veg until march 21st?

Thanks for the help. You guys are awesome = )

what? why would they start flowering right now?

its a little early to put them outside i think, but ive got 2 outside. they will veg until august probably. thats when my plant flowered outside last year.

swear they wont flower until we get to the winter light cycle??? our days are alot shorter in winter which is what triggers the flowring stage????

yeah im pretty sure you plants may start flowering bonique, not sure though. I know that my widows did when I put them out in march.

But what if I planted some seeds right now? Would they flower, or just veg till fall ?

lol, I am aware that plants flower later summer early fall. However they will flower in early spring. I did it last year, you can check out my grow journals for pictures. My White and Purple widow finished around May 30th.

Anyone know the answers to my questions?

if you put them outdoors after the last frost thinking "im getting a good head start this year" for me, living in the southern hemisphere at least FLA, plants started to flower too early since the days still arent long enough.im putting the newest ones witch havent started to put on flowers yet. back in at night under floro's to lenghten the daylight. im figurung it out the hard way. usually the only way i seem to. im leaving everything in the ground do its thing. i read they will re-vegg when the days get longer(around april). or maybe its still early enough they will finish. i know next year i will wait till at least until the end of march to start putting them out. any input is appreciated. hope this helps someone w/ the same problem.

Here's a story along that line FWIW. 40N. Put a 2' BF Nightshade outside 7/15 (2 months late for around here) Harvested 10/11. Got 12 oz. Trichomes looked perfect, Plant, buds looked great except not real sticky. Plant looked like a Sativa Pheno. High was a spacey rocket ship ride that took some getting used to. No CBD? No couchlock. I was a working motherfucker. Once jar'd and cured, not much smell. Minimal turpenoids? So, a result of a Sativa pheno not reaching it's prime? IDK.

If you have plants that have been under 18/6 light they will flower any time you put them outside. They sense the shorter days and think it's the end of the season. I've seen 5 inch clones go straight to flower. This is my 3rd year of vegging indoors and flowering outside. I put my first plants outside the last week of February. I'll get my first harvest in about a month. I'll put my last plants outside in September. I try to put 3 plants out every 30 days so i have a perpetual harvest..
 
Yeah im in cali and ive noticed as has my neighbor the same trend socal has noticed. Nm the conditions outside, plants would never get 18 hours of sunlight away from the poles, so vegging at 16 to 24 hours of daylight will at least get you SOME healthy flowers when u put then outside. Seems like a healthy shortening works great, with huge jumps less effective. and tiny jumps being best if coordinated with natural light.

For example. 18/6 to 13/11, great results if days are shortening like september-november. 16/8 to 12/12 similar results. But going 20/5 to 10/14 with days shortening (around december), less robust flowers... But theyll be there.

Optimal jump or flipping would be small like 18/6 to 16/8 (going from indoor summer to July outdoor summer) with tapering day length thereafter. Im assuming this is best because it most closely mimics a massive single summer and single fall bloom.

The clone thing is also true, theyve already reached sexual maturity so their stretch during the flip (puberty for a seed plant) is much shorter, and their flowers will "resolve" quicker- reaching max trichome production 1-4 weeks sooner than a seed plant of identical genetics.

Welcome new friend!

Quick tip, check last reply date ;)
 
Lol no sweat. It was the only thing related to what im wondering on here. Thats how i ended up here. Hahaha i need to start a thread i think but dont want anyone to get pissed off.

Okay oh, so I figured I'd post my question here because the thread is still active. I'm wanting to set up some kind of Perpetual Harvest this spring and summer, vegging plants outside and flowering them inside. But right now I'm hoping to start the flowering process outside while a reveg project finishes inside. It'll be a few weeks before we're getting 12 and 1/2 hours of daylight... says April 1st. The Strain is White Widow, and I'm currently flowering a 3 by 3 indoors no. We just got over our last cold snap, and I'm at 35° north... I don't really want to push them any further than that Outdoors, and if for some reason the reveg project can't handle it Outdoors, well if she starts to reflower it won't hurt anything... I'm just letting her veg Outdoors all summer to collect clones.

Am I high jacking it started? I just didn't know where else to post, and I figured if we could get a rough figure on when the true last days to flower plants vegged over winter would be, like when's the absolute latest you could bring the plants outside before the vernal equinox and still get a harvest... if push comes to shove the flowering girls are getting the veg tent, and the reveg project is coming outside LOL

You cant get an “absolute latest date” between spring and summer equinox because of genetic and grow room variables. If you put inside plants (on 18/20/16/24 hours of light inside) to outside, 3 things can happen 1) you do it early enough you can finish a harvest before summer or 2) plants start flowering then have to slow down, reveg and catch back up to start flowering normally again in late August thru October, or 3) nothing, they just keep veging until when they are supposed to flower in nature, late august-October. No such thing as 12/12 in nature and all plants react differently to this. Or of course you can use autos to avoid the disruption, sometimes autos like going from 24 hour light to 13-14, and actually do more vegging before flower than they would indoor. Just my experience...

interesting... And nice to know. I'm going to leave them outside another week the weather I'm going to leave them outside another week, the weather is nice I'm not seeing any shift yet.

This is my third run, and they've all been photoperiods, so I've taken clones of each. I get this feeling I should probably start flowering out one strain at a time until I get the hang of each one and their eccentricities

I definitely agree that familiarity with your strains will help with that, but remember too that clones will grow and flower slightly different from seeded plants (even though genetically the “same”) because they have more flowering auxin and more percentage overall-total of bud sites, and they will flower even easier and faster than a mom most of the time...so putting clones outdoor early you may still see the weird leaves of reveg, a slight slowdown, then the revert back to veg-stretch in preparation for fall budding. Good luck and remember to protect from aphids, mites, moths/budworm caterpillars and finally botrytis. IMO outdoor bud is the best but it can be tough to cross the finish line outside, lots of challenges not seen indoor.
