Cambio de fotoperiodo

The height is good if you plan on filling canopy a bit more; keep spreading the stems 1 square across the trellis whenever a stem pops up past the net, and keep pushing them a square wider in any direction that needs filled for a week or 2 till the canopy is as even as you can get it, then when your ready, switch. If you are not planning on filling the canopy, then I'd advise you to raise the net up a foot or two, plant will shoot up vertically during stretch, the trellis where it is now wont support much of anything down there, if you get any sizable cola they will just flop right over with the weight. Use the trellis more for support of lateral branches, or use it as a makeshift screen for scrog, If you do scrog style I'd get a 2nd trellis myself. Best of luck ol buddy ol chum.

Probably close... when you fill about 1/2 of the area, it's usually a good time. A lot of this depends on the plants, too. Some grow a lot more than others after switching to 12/12 hours of light/dark. Check out my progression pictures at beginning of week 11. I flipped at day 41 for reference. You can see the difference between a big stretch and a normal stretch. There are some top-down perspective pictures to compare, but they aren't grouped together. you can see how much space my plants coovered around day ~40 compared to 30 days later when stretch ended. Week 7 has some top-down perspective pictures to see just how much space they covered after flip. I expected more stretch. In retrospect, i trained a bit too long after flip. I wanted a bit more vertical height for 5 of those 8 plants. Can't always predict correctly. growdiaries.com/diaries/245627-zoap-oreoz-blueberry-cookies-garlic-storm-2-grow-journal-by-001100010010011110

hago lo que tiene razon y venga lo que venga the girls will stretch during pre-flower, I use this stretch to fill out my canopy, if you spend your time making the canopy perfect in veg, then you still have to watch it carefully and work with it during the pre-flower stretch (the way I see it is that my work in veg is going to be mostly lost by the stretch anyway, unless it is really tight manifolding or something that takes even longer) like others have said, the cultivar and genetics in general can dictate the stretch on a plant to some degree. IME, the stress the plant is under during pre-flower is the largest determining factor for the stretch I'd smash the netting into the plant, flip her, then slowly work the netting up as she grows while feeding into it. It won't be perfect but you won't be twiddling your thumbs in veg in a week or two.

The indicas tend to stretch less than the sativas and I guess yours is a hybrid like 90% of whats out there.That needs to fill out more,those others arent even touching the net.I would have them all touching the net.You can always cut them back. if they get too much.Check what the breeder says about how much that strain stretches.If there isnt any info from the breeder then just check what the cross is and how those strains stretch.All the info is out there.You may get 20cm extra growth during the stretch but then you may get 5cm but its more than likely to be 20cm.When I switched to led,s from hid lamps several years ago I stopped having the fan blowing on my leaves as the leaf temps need to be high with led,s due to the lack of infrared.I now have the fan blowing over the top of the plants.The ideal leaf temp is 28c,if I go under 27 with my strong lights my leaves start to pale.
