12-12 from seed community journal

I basically germinate them, keep'm under 20/4 for 3 weeks, re-pot into 1.5 gallon (6.5l) and toss'm into the flowering room. I use regular seeds......made approx 150 seeds. After 2 weeks in the flower room the males show pretty quick and are eliminated

100X100 is that a 3ft X 3ft? Roughly 2 gallon pots....you could fill it with 12 or so and if it gets too packed, trim a bunch of the lower and side shoots. You'll end up with all main colas and a lot less trimming

Yes, 3x3ft and about 3 gallon pots, americans and their crazy messurements
But i still rock the american flag in the garage

12? How ? I currently have 6 in the tent, and it's already to much i was thinking about 4 or 5

Typical 3 gallon in a 3 X 3 should fit 9 pots

Never cared to learn centimetres......Im a Canadian bro after highschool was a carpenter, drawings were in inches and feet
Never bothered to convert!!

I guess I’m a slightly younger Canadian, because they forced us to learn both the imperial AND the metric system in school, lol!
I’m a general contractor and what’s hilarious is that all the plans and materials are in feet and inches, but all building codes are measured in millimetres and centimetres, so converting is unfortunately a regular part of the job now.

Pardon my sidetrack, 12/12 growing is really cool, can’t wait to try some myself!

Oops! I always thought Canada also used centimeters and liters.
When i read forums like this i always have to google the conversions to celcius and liters, i never seem te remember

Like a sun tan line. Before and after.

That is kind of odd. Definitely looks like some sort of deficiency honestly.

I’d hardly call this one deficient, where it’s not purple it’s green as can be.

That plant is awesome. Definitely doesn't look like it has anything wrong to me.

You don’t have to be a dick…12 12 from seed isn’t about volume asshole.

Yeah dawg, it's a different way to grow. Not everyone needs 3lb runs to get what they need.

This method ran in a Sea of Green can produce a lot of weed but some just dont wanna deal with all that.

But canadians and americans use ml don't they?

TerpBeans · Apr 20, 2026

I tend to use millilitres, cap fulls, tablespoons, gallons, jerry cans AND 'that should be good'

You're right, i am in a 3x3 (90cm X 90cm) and got 9x 9 liter(2,38 gal) air pots in it which are measured 28,9cm(11,38") diameter, so it's pretty tight in there.

Morning Guys
The hollands hope is definitely a girl. Has stretched while I was away. The 2 NL girls looking good. The short one won't be long, will check the trichs later today. The taller one looks big to me for a 12/12. Could have 3/4 weeks left. Never smoked nl before so looking forward to it. The hh will be in better condition than the outdoors stuff I smoked 2 years back. Weather was against me. Looking forward to it.

Heck ya!!!! I usually do 6-8 oz with 4 plants. That's why I was able to get away without doing a winter crop. I still have 2 oz. Haha
I was just mentioning a deficiency due to the lighter color on the main veins on the lower foliage.

Got some Frosted Guava from OGSS going 12/12 from seed this run and figured I'd throw some pics up here and there. About 10-11 days in so far.

Tossing up whether I'll reverse one of em.
