The 12-12 From Seed Thread

A reputable Instagram grower I follow says he pops his seeds under 12/12 lighting to determine sex. And as soon as they show their gender he takes the females to his veg room while the males get culled. The females go through re-veg this way right? Is this technique bad for the resultant mother plant at all? Or will she resume vegging as normal?

I currently have 13 seedlings growing at the moment that are at about two weeks old. I was going to let them grow about three or four nodes high and then i was going to take a cutting and throw the cuttings in a cup of water under 12/12 lighting to determine sex. But now I'm having second thoughts...

The sprout from seed under 12/12 method actually seems more efficient and convenient than taking a cutting and putting the cutting under 12/12 lighting. Can I re-veg seedlings rest assured that the mother plant will behave as normal once she gets out her funk and is in veg again? TIA!

yeap, u will be fine, although, the reverting females will stretch thinking she is still in Flower because the hormons are telling her to stretch like normal. She will slow down, usually after 2 weeks, but will still grow out nice. Ive done it, as it fills out a scrog really nicely. You will notice pistils on all the new nodes also, but dont get scared, lol..

I run 12/12, i top after the 3rd node is complete, which is around 16 days. although my current Cherry wine CBDs, i topped at 10 days. then you should see pistils around day 24-28. as soon as you even see a hint of female, flip to 18/6. also, transplanting should be done at first pistil find, which i also call day 1 of flower if you keep them in flower.

I start in solo till then, and final pot when you see the first sign of female. 2 gallons works great.

Think about it this way, with an 18/6 cycle the females show anywhere from 2-4 weeks, males are more like 2-3 weeks.

Starting at 12/12
Week 1-2 slow growth & stretch
Week 3 flowering
Week 4-5 reveg
Week 5-6+ vigorous growth, at this point you can pull clones and/or flower.

Starting at 18/6

Week 1-2 normal growth
Week 3-4 vigorous growth & maturity, at this point you can pull clones and/or flower.

Starting at 12/12 is nice when your looking for a certain phenotype or doing a sog grow, but if your looking for the biggest possible plants in little time I would stick with 18/6, as it will gain you a whole 2-3 weeks of growth compared to starting at 12/12.

People will do differently and that's fine, but I feel I'm making perfect sense here.

My Blue Cheese 12/12 from seed. For me It’s been tricky trying to figure out when to start flushing because there was no 18-6 to 12/12 light time switch and I like to count my weeks flowering as soon as I switch from veg to flower.

This is the end of week 11.

Most strains will start showing sex after 4 weeks of 12/12 from seed, some take a week or so longer.
You are probably at or around 7 weeks of flowering.

Looks great DrAmber, thats why i start flower day count when you see the first pistil. When it starts those "spurts"of pistils, like you have now, its getting ready to be finished. Those are her final trys for pollen,..

She is finally sucking the green color out of her leaves and still spurting new pistils and foxtailing it. I have only been feeding water for a couple weeks now maybe even longer. When should I chop. I almost feel like feeding her again. When I think she’s done, POW! More pistils pop!! What do you recommend at this point ? June 17th will be 3 months total.

she hit a wall bro, still looks like 3-5 weeks away, at some point, she just froze in growing. maybe let her dry out much? almost seems like the roots were dryed out to much, and now has to form new roots to finish.

what light u use?

12/12 from seed, day 70 , day 45 flower. sometimes i raise the watts to 250 just for a couple hours a day, then drop back down to 185ish. Had calmag problems early on, totally hurt the progress, they are in flush right now, the big one anyways. The plant on the far left, was severally over watered at the beginning, and slowed it down ALOT, and was going to pull her out and bin her, but she started to get better, so i let her roll, but she is definitely 3 weeks behind.

It will take most plants around 100 days to be ‘done’. Some strains take longer, some not as long, oftentimes, even plants of the same strain will vary in flowering times.
The way to tell is to look at the trichomes, which will be clear, milky or amber. Each stage will give different effects. You can cut parts of your plant at different stages of color to find out which you prefer.

I do have a jewelers loop and look. I need to chop her all up at the same time to dry her properly because I live in a small apartment . I fed her last night for the last time. I am hoping it supercharges her to gobble up the nutes and finish strong. Now I will keep flushing until the pistils in the very last foxtailing have popped. At least 3 more days I feel will flush out the nutes I just fed. I pulled 350 PPMs from her run off yesterday, so it will be interesting to see what her PPMs run off is today when I water her.

Got another 1212 from seed run on the go :weed:
DSC06054 - Copy.JPG

Plants are in plant magic soil and in .75ltr pots. Light is a Scope220 (LM301B strips) from DIYLEDUK.COM in a 2x3x4.4' tent.

A few more than normal as I'll be looking for males as well as females. Males will be used to pollinate a few choice cuts I have in another tent and looking to store some pollen for future crosses.

I made a couple of crosses last run and planted 20 seeds, nearly all are up. Those are the Mint Julep and the Adhesive strains mentioned below.

Mint Julep is Mint Chocolate Chip Cookies x Kosher Kush F2 - Thunderfudge Genetics
Adhesive is GG4 x (Nepali OG x Goji F3) - MrBee

The Secret Cookies x and the Ogee Kush x are from Seed Junky Genetics

Strains,
Adhesive x (Secret Cookies x Kush Mints #11)
Adhesive x (Ogee Kush x Triangle Mints F1)
Mint Julep x (Secret Cookies x Kush Mints #11)

You ever done any chem strain I got a bag for a buddy a while ago and pulled close go 100 or more seeds I think this would be perfect to do with them as well is there any trick to keeping it one solid bud other than chopping side chutes any thing helps love your thread and 12/12 sounds interesting not having all the wasted time in veg
