12/12 from seed questions

doams

Member
strains:2x acapulco gold ,1x herijuana
medium: coco
light: 2x25w cfl
ph:5.8 from start

nutes: nothing yet just some phosphorus from ph down if that counts..


started 3 seeds 12/12 from day 1.
its day 20 no signs of flower yet

question:
when will they start to flower?
they are at their 4th nodes..

if they dont start in 10days it will be bad coz they are getting too big alredy :(

question2:
how to keep em small?
should the light be cut only to 1x25w cfl and a little water deprivation maybe?
and no nutes at all untill deficiency show yes?

Seeds don't flower on 12/12 cycle. They need to become mature before they start following normal flowering times.

If your looking for small plants, then you need clones. Take those seeds, sex them, then clone them. That seems like it would be a better start for your situation.

You've got a bit to go, bud - the 12/12 will speed up your process, but they aren't auto plants. Give it more time, you'll know.

He's doing a 12/12 from seed grow - there are a few threads on this grow type here. Controversial but legit method.

They will flower - but he's at 20 days - WAAY too soon for flowers.

Prob another few weeks yet before signs appear.

They will be much shorter than a regular veg/flower plant - give them all the light you can & don't starve them.

Read the 12/12 threads, my friend - you'll be fine.

the space is limited by height the idea was to light starve water starve and after flowers starts to show tune everything to max. the light to 3x25cfl and give em plenty of everything but not sooner than first signs of flower. they need to stay very very short but they are getting big. bit nervous as this is first time 12/12 wish there is no space limit but there is. after some disasters last run decided to not use micro pots coz ended up drowning roots for days which killed few plants this time they are in 2litres/heri/ and 3litres/two acapulcos/ pots but because of this they are gettin bigges wider etc. which worries the head a bit.

will try to post updates at first signs of flower here and also in this thread:
https://www.icmag.com/ic/showthread.php?t=51760&page=145
was under impression that seedling starts to flower as soon as flip to 12/12 looks like that was all wrong.

so back to the first question it will show flower as soon as the plant is mature enough right? guess something like 5/6 nodes and around day 30 or a bit more min. yes?

You can top at 4 or 5, but you are stressing the plant with the early 12/12, so maybe use some tying down for all new shoots.

The 12/12 from seed is tough to say re: flowering - like I said, read the thread(s). Long read but great info.

will not top em due to limited space last run heri overgrowed the place like 2 times after top and it was in half liter pot so not doing this mistake with this genetic again.
took too many samples even done supercropping when there was nothing to smoke..but plant did not make it due to overwatering coz of small pot. still looking for best way to grow the shit in limited space one day there will be whole room with big trees lol.
but that wont happen anytime soon sadly.

yeah reading dem
threads good info in there.

No man you wanna show tune it to the max first then let the flowers boom.

only concern is that they will overgrow the space before showing flower but since its day 20 it must! happen soon lol like 2 weeks max if not there will be more experience gained at the cost. isnt the exp. always gained at the cost of something priceless lost?
maybe thats how life works that f. bitch.
oh well..
thx for advice man :smokeit:

I got plants 12/12 from seed starting to flower @ 3 weeks. Thought it would take more time. Switched to 18/6 cause I'm not ready yet. Got a male friend only 8" tall about to drop pollen.

The worst thing you can do is to starve them, that will lead to them taking even longer to start to flower. If height is the issue you can bend them over and tie them down. Good idea to keep it to single cola plants with 12/12 from seed.

yeah heri will need some bad ass lst done to her otherwise it will be out of controll so no single cola for poor girl but bet she likes it will tie her into circle several times probably and also dem shoots it will be a mess for sure lol.

dunno bout acapulcos but compared to heri they are like 20-30percent smaller overall so if they show boobs in a week its possible to hope for single colas but no idea how it will go.
will not starve em thx for this one good info!

Wow doing everything that you can do wrong your doing it lol I've noticed whenever my lights are off weather my plants are in veg or flower they stretch more then when the lights on and starving your plants from food will slow it from maturing, and 20 days you should have more nodes but that might be from ypu not feeding your plants

He's right.

Tricks to Stop Stretch.

As much light as possible as close as possible without burning.
Higher temp at lights off than lights on.
keep bending and tying down. Try not to supercrop or top when going 12/12 from seed.
there are additives available that also claim to help with stretch. never used so can not attest to whether they work or not.

Usually takes about 3 weeks for plants to start showing flowers on 12/12 from seed so should be soon. Only other thing you can do is get a different genetics that is not so tall to begin with or get a bigger space.

Just keep doing what your doing bro, don't starve them though just water regularly.. If width isn't an issue and height is the only thing you have to worry about , if I where you I'd already start training and top them.

Most likely your always going to have a lot of stem until the first node/set of leaves. Since they're still very young it's perfect because the main stem is still fragile so it's easy to bend/train. Unless you replanted into different pots and have the soil at first set of leaves..

But doing the training and topping will help you keep them shorter but your still maximizing yields and use of space. Since your cab is all flowering maybe even scrog? I don't usually put nets but it's an option..

That's all my personal opinion from experience and opinion but please don't starve them lol. It'll probably stress them out and if they don't herm you'll prob hurt yields if not then possibly kill them.

if they dont start in 10days it will be bad coz they are getting too big alredy :(

The size of the pot will control the size of the plants. Small pots = smaller plants no matter what.

If your growing sativas and really limited by height space you shouldn't use a pot bigger than 4 to 6 inches.
If you put a pure sativa in a one gallon pot. Expect to have 4+ foot tall plants. If you go for a 5 gallon pot
or more I hope you have a greenhouse size environment.

Indica plants don't grow as tall so you won't have the same height issues with them.

thx all.
they got their first food today /just bloom nothing else/ coz they were a bit yellowish green on top leaves not yellow just a bit brighter green but yes they are getting damn big. really hope they will start showing pistils not later than end of week or its fubar there is nothing worse than a plant growing above lights hate when that happens.

bit confused what do you mean by 4 to 6 inches a cube 4x4x4 or 6x6x6 inches?

not familiar with the inch thing using cm and kg over here :)
but its possible that they are in kinda bigger pots like 2 and 3 litres pots will not be using anything smaller coz afraid to drown em again due to head stupidity :D

I meant pots of 4 or 6 inches in size.

1 inch = 2.54 cm

4 inch = 10.16 cm

6 inch = 15.24 cm
