Today will be the first "Night" and when the lights come back on at 5pm it will be the first "Day" of Flower. However these were from seed, so it will take a little longer for the transition than it usually does from a clone. These two are still juveniles.Now thats a scrog!! Very Nice Jandre.
How long have you been in flower if you are?
BTW good weed to you Sir
Hey! Thanks for the rep! These will use the Diminishing Light Schedule. As these are from seed I'm expecting almost a month of transition, from what I've seen from previous runs in the Cardboard Flower Box, so I will start diminishing in about 3-4 weeks, rather than the normal 2 weeks of 12/12 after switching from 12-1. I just wanted to kick start these seedlings right from the start. It's partly controlling size more than anything that I went ahead and flipped them to flower.very nice jandre, reps if it lets me,
have you ever tried dls for flower after using glr for veg, or is that what your doing here, if you are which dlr schedule to you follow as i have seen a few different diminishing schedules so thought id ask if their was one you stuck to or if you just went with what you feel is right based on growth,
also do you find all strains respond well to glr, im a bit on the fence, im just about to flip my light back to veg for the next round of plants so might give glr another shot as i didnt use it last time round and growing clones and seedlings of the same plants so was thinking about giving it another try this time round so i can compare growth and check how long i have the plants in veg for before flipping to flower at the height i like to keep them at,
Thank-ya sir!Nice update J
no worries, reps are well deserved, i found that using dls to early slows down flowering,, it just seemd to slow flowering down by adjusting the lights to early, so i think your spot on by adjusting the light 3 to 4 weeks into flower,
as you used glr to veg then they will flip to flower pretty soon, at least i found mine pretty much flipped to flower with very little stretch as they had been stretching under glr, but you will easily fill the scrog, with plants that big it wont take long till your trimming it back to keep it under control.
do you know if anyone has used 11-13 for flower with the 11 hours been the lights off period and 13 hours on, i know plants will flower with as little as 14 hours of light so 13 hours of light should keep plants in flower, im just wondering if the extra hour of light would give the plant more time to flower or even reduce the flower period due to it getting an extra days worth of light every 12 days, i didnt know if this is something you had tried or knew anyone who had tried this,
Cannabis needs 14.5 STRAIGHT hours of light to keep it in Veg, but this is because of the 9.5 hour length of the DARK period, and not because of the light... By using GLR you are tricking the plant into staying in veg by giving it no more than 5.5 hours of dark at a time, thus he 1 hour on halfway through the night. The 1 hour of light is enough to destroy the flowering hormone that builds up in the dark period. However, it builds to a critical point that send the plant into fast flower when switched to 12/12. Seedlings grown to FULL maturity will switch in days rather than weeks, thus reducing the stretch. HOWEVER... the seedling MUST be grown to full maturity or it just will not flower. it'll show sex, but flowering is another story.interesting, thanks for the info, i might give 11-13 a go next time round, i didnt know glr was not good long term but i dont plant on mothering a plant so id only be using it for 6 to 8 weeks at the most, ive been trying to find some side by side grows with glr and 18-6 to see if glr really does produce better results during veg,
some say it works well because it tricks the plant into thinking 24 hours is 2 days instead of 1, i tend to think that it tricks the plant into entering the rapid growth 12-12 starts but by giving 1 hour of light it actually prevents it from going into full flower, from my own experience when i grow plants under glr from seed they tend to show sex a lot sooner so thats why i got the impression the plants go into rapid growth to prepare and start flowering but they dont actually start flowering,
so 13-11 slows the start of flower, im glad someone knows something about this, 11-13 sounds interesting and worth trying, id just like to know more info on how it actually makes the plant react, do these plants flower better with more dark period like 11-13 or 12-12, i just wish i had room to do some side by side testing, so dls must work well due to the extra dark towards the end of flower,
lots of stuff to test and not enough grow rooms to do tests in, sorry for all the question but thought you are the man in the know,
ill reps you again when it lets me,
I love this journal... I often learn something new +reps Janre
Yeah, we're planning on checking out the Olympia MMJ farmers market in the next couple of months. I just keep it put off a bit until we've got out tents and lights, because it'll be hard to not buy something and I tend to be the over-responsible one, i.e. "it would be a waste to go and buy stuff now when you have a tent and lights to purchase so you aren't forced to spend a lot of money at a dispensary each month", so we're waiting to check it out. I do think the concept is awesome though
We hit the regular farmers market a couple times a month or more for groceries.
I avoid the main grocery stores as much as I can. We get most of our food from the farmer's markets and out of our garden. Since we started doing this, we both notice that overall we don't feel as bad, unless we decide to "splurge" on those things we don't eat anymore, then we feel like crap for a while afterwards.

Well, you are partly right. I have grown from bean under 12/12, and I've found that seedlings will not flower until their genetics says to flower. After that, the only way to keep them in veg is 12-1 or any other Veg cycle.
I have also found that 12-1 should ONLY be used when preparing plants to go into flower, and should NOT be used for long-term vegetative growth, as in mothering plants. The average is about 9 months of healthy growth, and then, for some unknown reason, if kept longer than that, there will be a sharp decline, and eventually death of the plant. Learning this cost me a few rare strains, and was quite a blow, but with that lesson learned, I know now that for mothering it's 24/0 or 18/6 for me.
Clones taken from those mothers, can easily be kept in 12-1 for preparation for the Cardboard Flower Box. This is the system I use for any plant I put into the box. Cut from the mother, and root under 24/0. Once rooted, they go into 18/6 to veg-a-mite (hehe) for about 2 weeks, or so, depending on growth observed. Then it's down to 12-1 after that for about 4 weeks to get some good size and to build up a good amount of primordial flowers. After that they're held for at most 2 months under 12-1 and into the box they go.
Now as far as the 13/11(the first number when talking about light cycle (i.e. 18/6, 12/12, 11/13, etc...) is always the "ON" or "DAY" period), the added light will actually slow the transition into flower, and thus create lots of stretch, in my experience. I've also flowered under 11/13 and got pretty good results. Twelve12 flowered his perpetual SOG and breeding projects under 11/13 with fabulous results. I also did a flowering under 10/14 to see if the flowers have an increased resin production, but this added a grassy taste and alfalfa smell in all strains flowered that I can only assume was caused by reduced photosynthesis time leaving more raw nutrients in the plant... I just can't figure out why DLS doesn't do this as well. I guess that by diminishing the light, it is more natural and triggers something in the base genetics of cannabis, to take less nutrients, and to use what is already in the plant to create more resin, and 10/14 doesn't supply this trigger.

Oh, no, no, no! I go very much below that! I start at 12/12 and end up toward the end of flower at 9/15. That is the Diminishing Light Cycle. What I was saying above is that the 11/13 cycle works VERY well for a Perpetual SOG type grow where there are plants constantly rotating in and out, and a diminishing cycle would not work very well for the newer plants coming into the mix.<snip>
Are you saying you don't go below 11/13? I reduce mine down to about 10/14 over the last 4-5 weeks. I've always been nervous about going lower as I become concerned about reducing the yield by not giving the plant enough energy. hmmmm. maybe I'll only go down to 11/13 this time and see what I think. Maybe 15 minutes shorter each week for 4 weeks.
I was going to say something similar. I'll just emphasize a couple of things you mentioned and add one small detail.
Many (perhaps most or all?) of the plants growth processes are controlled by hormones. These hormones react to environmental stimulus and this leads to the plant responding. One example is gravitropism. We see this when we bend and break plants to promote branching. The plant makes a growth inhibiting hormone at all active growth points. This hormone always travels down. This is why, if left to it's own devices, cannabis will form the classic christmas tree shape.
Flowering, in response to the change in light cycle, also happens due to hormones. In this case, the hormones are photosensitive. They decay when exposed to light. It takes ~12 hours of uninterrupted darkness for the flowering hormone(s) to reach the threshold that triggers the plant to shift to making flowers. So whenever I think about photoperiods, I care more about how long the dark cycle is.
Here is the way I explain it in my head... At each node, the plant is making new cells. Some are stem cells. Some are leaf cells. This happens at every node. What type of cell it grows into is controlled by hormones. I think this also where the flowering hormones are being created. When there is enough of the flowering hormone around, ie it's been dark for 12 hours, these flowering hormones are able to overpower the other influences telling what type of cell to create. Kinda like it's a factory that gets told what to make over a speaker system. They can't 'hear' the instruction to flower until it gets 'loud' enough.
GLR works because it doesn't allow that flowering hormone to build up to a high enough level. If it normally takes 12 straight hours to get to that threshold, GLR let's the plant to to that threshold minus however much of the hormones decay in an hour. It's essentially a 13/11 schedule, but by moving one hour to the middle of the dark period, you can keep the plant in veg more reliably. In theory you could put a couple half hours in there, or put the hour a couple hours in or a couple before they wake up. All I think that matters is you don't allow 12 hours of uninterrupted darkness. I think the 12/1 GLR schedule came out of a compromise between power savings and hindering growth rates. It's also very easy to visualize the schedule by looking at the type of timers most of us use.
Sorry for rambling on Jandre
I learn a lot on your journals.
