The 12-12 From Seed Thread

day 62 12/12 light cycle Nirvana Raspberry Cough seeds:


http://www.kindgreenbuds.com/marijuana-strains/raspberry-cough.html

These plants are 62 days into growth using the 12/12 from seed method.
10 seeds were germinated, 9 sprouted. Ten days revealed 2 males and 7 females. 15 days showed male pollen, and female flowers. At day 17 the females were pollinated and the males were discarded. At day 50 the light cycle was changed to 10/14. Four females survived the grow showing very promising seed bracts. Lights used are one 150 watt HPS and 12, 28-watt CFL's. Nutes used Schult's plant food 10-15-10 every third watering, with epsom salt every second. Temperature kept at 82F

Switchable 600w running at 400w for the two.

Mantiszn what light were you running?

Why you go to 10/14?..rw

 

[dankerous]

I've been pouring over this thread trying to digest it because I am considering doing some 12/12 from seed growing. I'm still not clear on a few things and I know all of you doing 12/12fs don't necessarily agree. But generally I still wonder:

1. do you think response to 12/12fs is strain dependent? Do some perform better than others?
2. I grow NL and for me it flowers 8 weeks, 9 tops. Does that mean my NL would harvest in 9 weeks from seed?
3. what might I sacrifice in yield?
4. if it doesn't in 9 weeks, why not just veg 24 hr for a week or 2 before 12/12? It does seem like 12/12fs might really be vegging for x time, but vegging at 12/12. I don't see the advantage in that except, as with me, you want to start seeds in the same room where others are going 12/12.

Maybe this has already been summarized somewhere, if so point me to it! Thanks

1-yes massively so,you have to do sativa heavy varieties normally,most indicas will not preform,sativas are equatorial so generally only get 12-14 hrs light with 12-14 hrs dark at max too,.
2-answered that in question #1
Alot if you did an indica,tested it with some white berry,3 week veg gave a nice yeild,12/12 was pathetic.
4-plants veg until they reach a level of hormonal chemicals then they go into flower,it takes 2-4 weeks at 12/12.

The advantage is perpetual harvest,of plants that are more controlable and also gives you the ability to choose to do lots of varieties instead of one,also seed plants have hybrid vigor which clones dont,so preform better to some degree.

Mantiszn wow, you got 5 ounces off 2 with 400w? Coco?

This is a photo of four plants grown under identical conditions, using a strain from Nirvana claiming to be 70 Sativa / 30 Indica. Plant growth is 62 days. As one can see, the development varies radically. View attachment 2073824

 

[mantiszn]

No averaged just under 5 oz off each plant..
Blueberry gum was about 4.6
pineapple express was 5.3 or there abouts so just under 10 in total.

coco and airpots .. What was even more amazing was they were both squashed into a dr60

thanks breeders boutique

You probably had your light too far away during your grow or something along with many other problems I'm unaware of. A 150 hps can do much better than that. It's also near impossible to breed plants at 17 days old. A male can show sex in 17 days but then you're looking at another 2 weeks beyond that to get pollen from him.

Here is a picture of a strain that is mostly sativa-chemmy jones (og thai x trainwreck x chem d-Bx chem d) I did 12/12 from seed
She was about 87 odd days from seed there,I know what I am talking about

[kether noir]

something i am not totally sure about, but assume. hence my asking you lot.

if and when someone starts 12/12 from bean, it grows. however it is short as many of you know (hypothetical, i dont have any 12/12 from bean at the moment)
so if one were to clone the shorty. would the clones get big in veg? (i remember reading something that said clones get around the same size as the mother. although ive read re-vegging works. and this makes little sense.) are they to be midget clones? or have i stumbled upon misinformation.

thanks mates

You going to have start using a chain to hold that gal back, dank.lol...rw
That should be your avatar when ready to harvest it.

 

[mantiszn]

these plants look stretched and stunted.. bummer

Been harvested and smoked some time ago,currently doing some Tga Subcool-3D, that I have pollinated with the stinkiest male chemmy jones,some thing I have wanted to do for some time,and found the right pair to cross,both have similar structures,start of growing like an indica,then in flowering go more sativa like,with thinner leaves etc,so hopefully they will pass on some nice traits to the seeds they produce,there should certainly be a keeper,and she has been heavily pollinated,so I imagine I will get atleast 100 plus seeds(as I pollinate early to only waste preflowers not my entire buds),my aim is to produce a fast flowering super connoisseur sativa heavy strain,that meets my tastes,will continue breeding with it until I have what I want,may even add some cheese in the mix eventually

sound tasty to me. Love to grow some of those seeds.lol..rw

If you take a clone and veg it normal it will get as big as you let it.

 

[dankerous]

Heres my current lady,the Tga Subcool 3D,that I have pollinated with Chemmy jones pollen,about day 21 of flowering I think,

 

[roofwayne]

that's the way, smoke and resupply at the same time...rw

thats what i thought. this bloke is feeding me crap. i was going to say if you revegg they get bigger so the clone thing made sense. thanks supchaka

 

[fir3dragon]

if i do this, what size pot will i need? the smallest possible.
