PRE VEGGING CANNABIS PLANTS FOR THE OUTDOOR SEASON AND HOW TO AVOID PREFLOWERING PLANTS WHEN PUTTING THEM OUTSIDE???

Ive started all my seeds for the 2021 outdoor grow season here in january. My goal is to get them 4 feet tall and established so when they go outside theyll be monsters! only problem is avoiding the preflowering part in the beginning of the season ... normally happens when you put your plants outside from a warm tent inside to colder 60 to 70 degree weather they get shocked and thats one way they preflower, another way they preflower is when you give your plants to many hours of day light when there use to 14 to in may june going from 18 hours of daylight inside to 14 15 can make them preflower as well ... last year i only had 1 preflower and i did a 18-6 light cycle and i started my seeds in march... this year im starting 2 1/2 months earlier started jan 18th... would like to get peoples feedback on this as its very important for me to make sure my plants dont preflower id like to hear eveyones different methods on how to avoid preflowering plants i know some people use artificial lighting to revert them back into veg for the ones that do preflower... Idk weather to start with 18-6 again or try something different this year???

Either way photoperiod plants shouldn't go into flower unless they are given 12 hrs or less of light/daylight. Should be fine tossing them outside later... but if it was me.. I'd skip spring entirely. Too much rain. I wouldn't put it out to be subject to all that.

Wait until June 15th.

Hope you have a ton of head space for plants that big inside. 6 month veg is going to take a lot of work to keep them manageable inside.

I have to say something about this.

My outdoor plants "flipped" at 14 hours of sunlight.

They finished roughly when it was 12/12 give or take.

They definitely don't need 12/12.

If you put them out later April you will be fine.

A friend of mine begins his outdoors grows at the end of February. By the time it would begin to flip due to sexual maturity the sun hours have more than covered the situation to keep on vegging.

I suggest end of April to send them outdoors.

No worries brother. All good. New knowledge is poweful knowledge.

Check this out.

Here Sept 23rd is the beginning of true 12/12

If I had to harvest in January or February I would do a perpetual grow outdoors always.

That would be lovely tbh.

Maybe where you live, but where I live, we still have snow on the ground. June 1st is the earliest plant in the ground date here for anything, June 15th to be absolutely safe from frost.

Oh I was talking specifically about the light hours and what it takes to send it into flower. I guess I assumed PST lol

The weather is a whole different ball game.

Take them outside whenever you want, get low powered solar lights or string lights that turn on at dusk and stay on all night to help supplement extending light hours.

I don’t take mine out until June to harden off from indoors in California just because most of the rain and cold nights have gone away and I don’t have to supplement light.

I live in Vermont, it is 6 below zero here at 3:39 AM, waiting on a foot of snow tonight.

Ah. Yep. I lived in NY 28 years. Went to Connecticut and Vermont often. Your climate is hard regardless of time of year for growing bud.

When I lived in NY you really couldn't plan an outdoor activity weeks in advance.

Many times we would hope to go to the beach and wake up to rain.

I dont envy your challenges. But I salute your willingness to overcome the elements.

Oh yeah, if you don't like the weather, wait 5 minutes. Thank you!

subbed. i'm in michigan and doing the same thing. i got my clones 2nd or 3rd week of jan, they just started week 7 of veg and they're already WILD lol, i'll post pics when i water later. I have 6 in a 5x10 and am thinking i'm going to have to move 2 into my 5x6 tent and leave 4 in the 5x10. i have a 6x8x5.5 small high wall greenhouse that i'm thinking i can use with a supplemental little small space heater and a heating blanket by april if i really need the room. my pen is also wrapped in 4mil 3 year greenhouse plastic with rolling sides, so i'm not too concerned with rain or storms. they went from 3 gal pots to 15gal pots about a week ago and i believe i'll keep em in those for 9-10 more weeks and then transfer to either 45's or 65's (opinions on that?) to finish in. i have 6 more clones i just started that will run along side these, was originally going to flip them to flower indoors but decided to veg em out and see how big we can get em lol

The first two are pure Michigan on the left strawberry gelato on the right, zookies and black cherry soda, and mac1 and oreoz

I already put plants outside. Yep 90% of the forum would look at this sideways and tell me they will try to flower.

I keep my patio lights on overnight with the plants right under them. There will be no flowering, no reveg, and no issues.

When it rains I pull them into the shed with the doors open.

All this is workable. Light factors can be tweaked to make it work just fine.

The only true concern is if it gets too cold at night.

I am in southern AZ and have been indoors for years now, but finally have the chance to move back to both indoor and outdoor. I am running the nursery and veg and my partner is flowering indoors.
I have plenty of smaller plants that I can experiment with and since the weather is great I am going to try the following:
I will place a small plant from clone in a 1 gallon pot outside starting Marc 20th every week until they stop flowering. Sunrise and sunset are 12.5 hours apart right now and my plants are currently under 18 hours indoors 315 CMH. I have to know when I can tell people they can plant outside. I am rapidly making a business out of providing a grow service that includes plants now that it is legal here. I welcome any input but don't want to highjack this thread unless Massgrower dose not mind if not I will start a new thread if anyone is interested.

I could start today with the following Super Lemon Haze.

I will wait until the 20th the official equinox to make the test consistent.
