Check out the link in my signature A Guide On When To Plant Outdoors & Force Flowering Without Covers For Multiple Harvests: I tried to explain how light cycle and lattitude/daylight hours affect flowering pretty well.

This is probably the pertinent part to your question:

So basically, this late in the game while daylight hours are increasing quickly, I am good to take my seed plants from beneath the 24/0 light schedule and throw them outside with no worries of triggering flower, correct? They really need to go out asap... As I need the room in my veg area.

I am at 38° by the way.

At 38N your at around 14hr and 15 minutes dayight currently, The transition from 24/0 veg indoors to outdoors daylight hours would cause them to force flower from the 10 hour difference from never seeing darkness. On the Summer Solstice June 21st (37 days from now) the longest day of the year your at ~14hr and 45 minutes daylight and then the days start decreasing again. Since the increase in daylight is so minimal (like none) over the span over 37 days before decreasing again the chance of them stopping flowering and revegging is unlikely after being put outside.

You are on the same daylight schedule as Los Angeles in the example i gave, (longest day only 14.5hr). Which is the optimal location to do multiple staggered harvests by transitioning groups of plants from 24/0 to outside to force them to finish before the weather gets unfavorable.

Mean thread will follow this already picked up some good ideas.

If I wanted to prevent this, could I possibly start slowly decreasing the indoor lighting schedule to around 15/9?

 

[Ibechillin]

Yup, that will help them stay in veg until they flower naturally. Also wanted re mention strains with more sativa heritage are more sensitive to daylight changes because they veg in nature at only 13 on 11 off veg and 11 on 13 off bloom cycle, these are the ones most likely to reveg/monstercrop if put out from 24/0 to outside now, where as indica strains dont mind the longer 12+ hours days as much and seem to finish flowering and resist re veg.

Once I put out 1 m tall clones on March 1. because they grew too big in the box, so they started to flower immediatelly outdoors and almost fully finished till May 1. It was a warm season... it was fun.

800 out by the end of the week game on.

Woot!
Dude, that's a huge amount of work so far.

Best of luck Hoypare!

Just wanted to point out the trifoliate plant in the first picture, 2nd plant from the left. Is that all for one patch? how many plants were in the field of your 2017 guerrilla growing video on youtube? Thanks for sharing man your grows are epic!

Dont know if it is trifoliate mate,or just the photograph,its all from one seed batch,i will check tomorrow

 

[Easy7]

Good luck with your security. 800 is a massive haul. What do you figure you average per plant? I've seen last years, and very impressive. Think the vid too if that's you. The apache!

 

[Bud Green]

Good luck Hoypare.

I saw a few pictures of your garden last year...

Now that's what I call a "proper" English garden...

I talked with Duke Diamond earlier today and he recommends that I start turning the lights out about an hour per day until I get to a 16/8 schedule. I am going to take that route, so looks like im gonna be holding these indoor for a week or so more. I can see where he is coming from, that instant shock from 24/0 straight to outside is very likely to cause a trigger in flowering.

This give me more time to keep digging holes and amending the ground.

Speaking of which, I just had finished mixing and amending my 5 holes today when a pretty wicked thunderstorm rolled up on me and my pooch... We tried to throw some contractor trash bags over top of us and got under a thick briar/cedar thicket. Worked great for a minute and then decided it wasn't gonna lighten up anytime soon. Then not even 60 ft or so away BAM! Jolt of lightining struck a tree and it put the fear of God in both of us. He tucked his tail and we both took off in a run and I hopped on the atv and he followed me home. Yep, we almost got fried, literally, and not the good kinda fried either lol...

To beat it all, the moment we pulled into the drive way the 4 wheeler died and when I turned it back over the engine sorta made a clucking sound, may be the starter, idk yet... but without that ATV i'm outta business till its running again. Good time to transplant I guess and take advantage of the Storm... also its getting those holes watered in and water polymers charged haha...

 

[MountainBudz]

I'm also gonna have to be changing my light schedule*for cuttings anyways..about time I start rooting them and have em ready to be out by June*13th*or so.

 

[TychoMonolyth]

New moon and planting time.

Let the games begin!

 

[soil margin]

I'm so jealous Hoypare. I can only imagine that's gonna be some real goddamn fun out in the wild.

I have never had any strain flower when there is 14 or more hours of light. I use to always keep them at 16-8 indoors. Then I started doing 18-6. Then I did 24-0. Nothing started flowering. I went back to 18-6 because it saves some money on the light bill. Cannabis plants don't keep track of the light they keep track of the night. They notice if dark is longer than night or nights keep getting shorter. Those 2 things trigger flowering.

Outdoors at 40N they start to notice the nights getting longer sometime in July. On June 22 the longest day sunrise is 5:36 and sunset is 8:45 (15 hours and 9 minutes of light and 8 hours and 51 minutes of dark. On June 30 it is sunrise 5:38 and sunset 8:45. The night is only 2 minutes longer so they keep on vegging.

On July 10 sunrise is 5:44 and sunset is 8:42. Now there is 14 hours and 58 minutes of light and 9 hours and 2 minutes of dark. On July 20 sunrise is 5:52 and sunset is 8:36. 14 hours and 44 minutes of light and 9 hours and 16 minutes of dark. The dark has been increasing, the plants still in veg. July 30 there is still 14 hours and 25 minutes of light and 9 hours and 35 minutes of dark. But there has been almost 40 days of increasing dark and the plants IMHO start to enter the transition phase.

On August 12 sunrise is 6:14 and sunset is 8:11 so there is 13:57 minutes of light and 10 hours and 3 minutes of dark. This is when I start to see the first pistils forming on the strains I use. Which are usually indica or indica/sativa. I figure the transition started 2 weeks before. Around July 28th. That is like flipping to 12/12 indoors. But it wasn't a flip it was a steady increasing of the dark period from June 22 until July 28 or so. Sativas usually take longer to start transition and then take longer to flower. So many sativas won't finish because of those two factors. Also some short flower strains like a 8 weeker actually take less stimulus to start the transition so they might start the transition around mid July and might finish by the end of September.

So I count week one outdoors (like flipping to 12/12 inside) as August 1st. So and 8 week strain could finish Oct 1. A 10 week strain could finish Oct 14 and a 12 week strain can finish Oct 28. They are good guides to selecting outdoor strains.

Good post.

So what I'm gathering is at 40N you can veg indoors or offer supplemental lighting until July 28th and let mother nature take over and they will begin flowering. Meaning at 40N there still is about 10 weeks of veg time.

Yes. But you could also put them out on June 1 (15 hours light and 9 hours dark) or May 20 (14.5 hours light and 9.5 hours dark) This way tou would be vegging under the sun. If you can veg inside you won't have to worry about pests or prying eyes. Outside there is danger but a better veg light.

So Meaning at 40N there still is about 10 weeks of veg time.

10 weeks of veg time starting when? If you put them out on July 28 there is little veg time left. If you mean vegging starting now indoors or outdoors there is basically 10 weeks of veg left.
