Summary Results
Average Yield across 27 plants and 18 strains: 12.1 Grams. If we exclude the G13 that was taken early due to nanners, the average becomes 12.4 grams

Smallest Yield: Early G13 @4.8 grams. If we exclude her, smallest was 5.4 grams followed by 8.5 grams.

Largest Yielders: 20.6 grams, 19.9 grams and 18.1 grams.

8 were 14 grams or more.
9 were 10 grams or less.
10 were between 10 and 14 grams

Good stuff on the yield. I can't wait to get my true 12/12 going. But dam 12.1 grams in the avg. Just think if you can maintain that average ( I'm sure you can) with the same strain with 37-40 beans under a 600 that would be easily 1lb. Hers my 12/12 side project. I think they are somewhere around 10-17 days in 12/12. I need to check my notes for the exact date. They are a tad bit yellow but I'll fix that with some Tylenol. Lol

Tylenol...lol
Ahh, those look fine to me man. Are you keeping them in those cups or transplanting?

nice grow, would be cool to see how much difference maybe 1 week or 2 weeks of veg would
have had on the yield

I read the same actually, that a plant won't ever go into flower for 2-3 weeks, so you may as well normal veg for that time and then go 12/12.

This was a different experiment though, so not the right time for that.

Personally if he vegs for a week or two he might up having a jungle and unmanageable growth for 27 plants under 1x600 watter. 12.1 grams a plant is hella good for no veg time. Sea of green is king when it comes to gpw. I will also attempt to do a 12/12 but with 2x600's and 120 seeds. If I can do at least 12.1 grams that's well over 3 lbs. and easily 1.20 gpw. Plenty of medicine for you and your friends....just my 2 cents

When growing 12/12 from seed your right about that it takes 2-3 weeks to flower but only because your trying to flower a very immature plant. There's no way possible a seedling will produce pistils because there's no nodes so therefore it has to grow a few nodes/leaflets before it will flower. A plant that's been growing in veg for a long time won't take near that time unless it's 100% long flowering sativa but since it's been in veg for a while already most likely its showed sex and has preflowers on it so it will flower much quicker.

IMHO a plant isn't in veg until it passed the dampening stage of being a seedling. Once the seedling stage has past then I consider it to be in veg and that's usually between 2-3 weeks after breaking ground. But most people consider it to be in veg once it breaks ground so it more of a personal thing but that's why it takes most small plants to show sex because of being immature.

yeh ^ always nice to see, some folk still think 12/12 from seed is not possible
i was kind of hinting, i hope i see someone do a 1 or 2 week veg then flower
i can never get around to trying it myself

would be cool to see how much different amounts of veg time effects yield overall to find the best cut off point that suits different growing styles and situations
i think 3 weeks is very popular for folk to veg their plants so their are lots of grows around to see quite a few 12/12 from seed threads around too
not seen many 1 or 2 week veg then flower to compare to the 12/12 from seed

those i have seen suggest even giving just 1 week of veg before flower can significantly increase yield
although i am a bit sceptical about this as i find the biggest growth spurt is during flower anyway
so a long flowering sativa on a 12/12 from seed would still get big and yield several oz

peace

That is a very good question. From the moment I placed seeds into rockwool I was looking at 34 days until the 1st pistols arrived. Since the young plants are technically in Veg until they think are ready, running a veg cycle until day 20, for example, is definitely worth trying. Anyone wanna give it a shot? My gut feeling is that the difference would be negligible but who knows!

i have done 18-21 days from seed plenty of times, never any less,never done a 12/12 from seed either, although i have flowered cuttings as soon as they have rooted with no veg time
they grow in a similar central cola shape as a 12/12 from seed

plants at 18-21 days (veg photoperiod) from seed are just out of the seedling phase and have little nodes/branches forming
and might only be as small as 6 inch or so they go on to produce plants that can yield anything from 2 to 16 oz depending on the amount of sativa/stretch the genetics has
that's why i think the amount of veg can make less difference than the strain/pheno itself
if it does a big stretch due to its genetics it can grow branches before it shows pistils and will still get big overall and yield well

if you (see pistils) before any nodes/branches start to significuntly develop most strains from seed and even cuttings tend to grow a plant with one central cola and very little or any side branching

My current crop comes down Jan 5th (ish) so I'll have some space, only doing two plants again though, so kind of feel I need the veg time to get something decent. Plus it wouldn't even be comparable to your conditions.

Loving your work though, some great skills and interesting ideas

Merry Christmas to You!! Hot,good job!!!
A couple of questions I hope haven't been asked.If you were doing it again,
would you still use the same containers?
Did your high yielders come from the same
strain? Thanks !!!

Merry Christmas to you too!

I would definitely not use the same containers. I found that the containers I chose were adequate however watering them was a real hassle. I'm leaning towards a flower bed approach where they all share the same container.

The highest yielders came from:
Critical Cheese
Chronic Thunder
Critical Jack Herer
Northern Lights
