The 12-12 From Seed Thread

[Opie1971]

I wouldn’t advise removing all the fan leaves, maybe the lower ones, it’ll affect the plants overall growth.
2 to 3oz baseball bats?? Not likely, not with seed plants anyway. If your set on trying to get these results, your best bet would be to use clones from a plant that forms large colas.

When you get 2-3 oz per plant 12/12 from seed I take it that it’s from lots of braches on a bushy strain then?

I’ve started extreme defoliating now as i have 4 plants per square foot. I will have conclusive results in 12 weeks whether plants need those fan leaves or not

I usually let my plants grow 4 to 6 nodes and then I cut off the top 3 or 4 sets, leaving 2 nodes on the bottom for 4 branches. Sometimes I cut off the very bottom set of nodes and leave sets 2 and 3, like when the bottom set is a lot smaller. This makes 4 too colas instead of 1. I also cut everything off each branch, from the bottom to 5 or 6 inches up.
I have several pics back thru this thread, if I still had my old phone I could show you them, but it’s long gone.
What strain(s) are you growing?
Good luck man, and post your progress with pics.

My current round is rqs skunk XL I have 90 seeds in a dwc system 15cm per plant 4 per square foot

My next batch of seeds will be 90 rqs royal gorilla I’ll do the same with those seeds if these turn out ok

So far my findings are if I don’t remove large fan leaves the lower branches get shaded and they stretch to find light.

Since I’ve removed fan leaves the Lower branches are growing almost vertically with the main stem and tight nodes. When preflowers begin I should be able to top the side branches so that the first nodes on the branches produce a bud which should create some baseball bats.

This wouldn’t work if I left the fan leaves as the first node on the side branches would be inches away from the stem due to shading

This was the 90 RQS skunk XL at 11days since germination. Will get an updated pic when lights come on tomorrow

 

[SamWE19]

3 weeks old from seed as of tomorrow.

This is what they look like and how they grow if you remove fan leaves as soon as they have a stem

 

[SamWE19]

It’s on its 7th mode there

Quick question that hopefully one of u 12/12 FS guys with experience may be able to answer for me.I just popped some seeds 2 days ago. They are in starter pots now and have already broken ground. I have just about everything I need besides a new tent (still waiting) which should be here soon. For now they have been in my windowsill, which gets good sun. Since they are not under a light they have been getting almost exactly 12/12 light (its September, I'm on the east coast USA) since they popped. My question is if I put them under 18/6 once my tent arrives (1 week or less) will there be any noticeable negative effects or will they be fine so long as they do not stay under 12/12 for much longer? Would I be better off just running them 12/12 from seed for the whole run. I don't want to sacrifice quality. Yield is important too of course, but definitely less important than quality. Any info is much appreciated as I have never tried 12/12 FS.

**Strains are:
unknown male x Quattro Kush (Ethos)
unknown male x LeeRoy (Rare Dankness)

Thanks,
OG Cloud

You should be fine to move them to veg if you'd like. Cannabis just vegetates for the first few weeks of its life and no amount of light cycle fuckery will change this. Since its only a week - I wouldn't worry about it stressing out the plant very much. Of course, your situation is not ideal, but I don't see it causing any major issues.

Curious about these too -- are they your own crosses? What is this unknown male? If the mama's were growing in a room with all females - 9 times out of 10 its a Herm in the tent.. again, just curious...

One last thing to note @OGcloud808 - standard naming conventions for cannabis crosses have the male name after the female name, its done this way to avoid confusion.
example: Quattro Kush X Unknown Male - would be appropriate.

What yield are you getting from 12/12 from seed?

This really depends on the plant. Most F1 strains just have amazing hybrid vigor and can be 2x to 3x the size of a more worked line grown in the same bucket. I just recently yielded about 3oz from a single F1 (LVTK x Sour Tangie) while under the same light, two polyhybrid plants (Sour Tangie x Sour Tangie) only managed to yield about 50 grams.

Some strains don’t seem to like growing 12/12 from seed, and will stay small even with perfect conditions.

One factor that plays a huge role in how big a plant will get at 12/12 from seed, is how quickly it transitions from sprout to veg to flower. The more 'Indica' the faster the transition in my experience.

Thanks for the quick reply. Glad to know that they should be fine, I thought so, but i haven't ever had this happen so just wanted to be sure it wouldn't stunt them or stress them 2 much.

No, they are not my own crosses, your guess is as good as mine as far as the male goes. The seeds r from 2 dif sources:

The LeeRoy cross I am sure wasn't a hemie. What I do know is that there was more than 1 strain going at a time and several males were culled but clearly not quickly enough. Should be interesting 2 see what happens.

The Quattro cross was from some bud I got a 1/4 of. Some FIRE Quattro Kush it was, had a real SFV/ Chem funk 2 it with some sweet earthy/gas undertones. Could b the result of a herm or could b somethin else I don't know much else bout its story. Hope shes a girl the bud it came from really was great.

Thx 4 this btw. I was corrected by someone and thought that was incorrect. Guess I'll switch it back up again lol.

Heres a pic of the same Quattro that the seeds were found in. There were 3 in total, 1 was popped, 1 was a dud, and I have one left.

Looks great, I should have clarified, seeds from a herm, or herms in general should not be considered a bad thing. In fact, it would mean you probably have feminized seeds which I consider a win. I've grown out plenty of seeds from herm pollination and had some great plants. Some would argue that they have a higher probability of herming. ¯\_(ツ)_/¯

No worries, yea if thats the case then i if it is from a hermie

Im really considering just keeping the 12/12 light cycle to see what happens. Although I kinda want to take clones in case I get something i really like
(if its anything like its parent thats likely)

You should be able to take clones at 12/12 from seed. I do it all the time. gotta be quick but even if its into the beginning of flower it's still doable.
