The 12-12 From Seed Thread

I've got a ton of the cheap reflector leds. 4 "300w" and 2 "600w". The 600s are Meizhi and the 300s are viparspectra. It's about 1100w from the wall when I have them all going but I get massive rock hard buds so I don't mine the power usage at all.
Im using tents. have a 3x3 with two 400 hps in it, a 2.5x2.5 with one 400, and another 2.5x2.5 with two 600 LED's in it. Im learning about the LED and coco coir now. quick story is i ended up in the hospital back in November. 5 surgeries in 6 days. stayed in hospital for a month. All my plants died. know one to take care of them. Came home could barely walk and had 2 clones to barely survive. Vegged them for 3 wks. Put them under the 800 and they produced 140g together. Now i have every tent scrogged out. I took cuttings from those two clones, six to be exact. Strain is Reserve Privada Headband. i have a sour d pheno and a og pheno. I got about 9 strains vegging now waiting on these headbands to finish out within the next wk or 2. so im about to run a LED scrog and compare the yield and quality to the hps. Im curious to see if i get near or over what the hps produces. If so i will retire the hps.

It's just the experimental one plant :D

This has started 12/12 literally from seed. I placed the seed in water and gave her a good poking every hour until she didn't rise again :hump:

After that, I just put her straight in the soil and waited, 2 days after that she popped up but I had to take her crash helmet off (the seed shell) :lol:

I'm now on day 6 since she popped up, day 8 in total.

-Strain - Sensi Skunk
-140w in total CFL, mixture of spectrums
-Multi purpose compost, nothing else at all added but water

I don't know why the first pic is sideways but don't worry, I am not growing it attached to the wall :rolleyes:

I grew a Critical cheese and cloned it before flower. I had 5 clones that went 12/12 right away. When I chopped the mother plant I had as much weight on the one plant as the 5 clones put together. Yeah, it was fast but by vegging a couple of weeks I could have had double the weight off those clones.

Hi

Thanks for the heads up.

I read that it is dependent on the strain, some strains do great with 12/12. I also read that the cost of growing 12/12 rather than going 24/0 for a few weeks gives you more bud for energy cost in the strains that do thrive on 12/12

I do have the same strain that I vegged 24/0 for two weeks at the side of my 12/12 from seed.

It's more of an experiment on the strain rather than wanting huge yields.

Thanks once again
Appreciated

I've been doing this for a while, prolly 3 years, and if you don't have an extra veg space it's good for a perpetual grow. You're definitely not going to achieve the same per plant yields as if you vegged everything then flowered. If you expect that result you'll be disappointed, it's unrealistic.

If you have a space you can veg in you're wasting your time growing 12/12 from seed regardless of what strain you grow. It's great if you like variety and want a 12/12 grow space year round without a separate veg. space.

You can definitely fill jars, but if you have clones/quality seeds and yield is the goal this is the wrong tree to bark up.

The only strains I've had do poorly are strains that don't stretch. Generally I hit 2 oz from a 2gallon (1.5 actual) gallon home depot bucket on strains that double in height. If it doesn't stretch for shit sometimes it can be as low as a half O. Which is shit by anyones standards.

I'd say by week 3-4 flower if you're not seeing good bud sets on a non-stretching plant you're better off to chop it and fill the space with something else. I've had short plants put out, but you can tell if it's going to be acceptable by that time usually. If it's not showing good signs by 4 weeks then I'm not going to risk another 4-8 weeks to find out and be even more disappointed. <--- obviously this depends on strain flower times.

If you plan on doing this perpetually you're gonna need seeds started every 2-4 weeks or so. You will burn through seed stock this way. If you're paying big money for your seeds then less veg. time equals less return on the cash you invested in those seeds.

I know there's been lots of talk about decreased quality, I haven't seen it. Some of the best pot I've grown has been this way, also some of the worst :-) it's just how it goes.

You absolutely need to lolipop or your yields will be fucking garbage. 25% off the bottom of the plant at least, try and do this a tthe end of stretch so nothing gets slowed down at all. Stopping that stretch is Not good.. Seems like if you don't it effects yields more than if you were to veg. and not lollipop, I could be wrong but this just seems like a general observation i've made with 0 proof to back it up.

The bottom line TLDR no bullshit: If you have a space to veg for 3 weeks you will always have better results that way than if you grow 12/12 from seed. The extra light hours will increase your yield it's just how plants work. If you don't have the space and don't want to veg/flower/veg/flower/veg/flower this is an amazing way to always have flowers in the grow area.

If you are in a 4x4 or bigger you'd be better off to get a couple 2x2's and veg instead of doing this in a 4x4.

My end heights generally around 3 +\- feet if interested.

Thanks man. I do have a question actually. Do plants seem to grow a lot slower for the first few weeks of life as opposed to a veg light cycle? I know with less light it will be less growth but is it a really noticable difference? This grape ape is like 17-18 days above soil and its growing super slow.

Not that I've found, no. Yours looks perfect. It will begin to go into pre-flower stretch in another week or 10 days. If you don't top, expect it to still reach ~ 30" give or take depending on strain.

I used to grow 12/12 a few years back. Not all strains react well to it, that's for sure. Grape ape has purps in it, which are slow to veg in normal conditions. I can totally see how they would crawl under 12/12 and probably not get too big. Your plant looks healthy.

Hey folks quick question, should I transplant into A larger pot before they start to really take off blooming.

I did. I started them in cups or #1 nursery pots and transplanted to #3 before stretch got too far going.

Here is 1 I did not transplant in time and left to bloom in the 1 gallon (3/4 gallon actual volume)

Didn’t bush and branch out like the up potted plants.
