12/12 from seed - 9 varieties.

[Taos]

This is my 4th grow. My third was a very successful run of 3 blueberry, mainlined or fluxed.

This grow, I will be starting 9 different plants, and growing 12/12 from seed. I hope to finish 6-8 plants.

Strains:
- Querkle (regular). 50/50 on male/female.
- Jack the Ripper (regular) 50/50 on male/female.
- Cookies and Kush (fem)
- Blue Mystic (fem)
- Green Crack (fem)
- Blue Dream (fem)
- Girl Scout Cookies (fem)
- Zombie Kush (fem)
- Bubba Kush (fem)

I am going to light with 8 CREE 3590 COBs @3500k. They currently run at 50w (1.4A), but I hope to be able to run them at 62w (1.75A) by the time they are into flowering.

I have never started in a plastic solo cup (usually use small air pots), so I will do that. The plants will be grown in Coco in a smallish 8" diameter x 8" tall air pot, which is about 1.35 _liquid_ gallons. Probably a 2 gallon pot. Nutes will be Canna line + microryza fungi during transplant + Mammoth P with 100 PPM tap water and a small amount of cal/mag. I don't have a written schedule for 12/12 feedings.

I expect all kinds of problems with differing plant size, finishing times, nute requirements, but overall, I am hoping for a chill-n-easy grow.

The seeds spent 12 hours in distilled water, and are now in a damp paper towel.

Less than 36 hours after putting the seeds into distilled water for 12 hours, then moving them to a _damp_ paper towel, 8 out of the 9 seeds have developed root, and have been moved to coco. Using a plastic fork tine, I made a hole, and the seed head is 1/4 to 1/2 inches down. The coco has only been wet with distilled water and placed under lights. (I need to determine how many lumens/lux for the first few days.) I worked a lot today, and will again tomorrow, so I am tired and being careful to not make mistakes by moving too fast. Tomorrow, I will make a ph'd solution with rhizotonic, I did not use micoyiza fungi in the seed hole. I want have lights (12/12) turn on when I am at home and have time for the garden, and am deciding which of two possible ways I can go about it.

Early game pics (pretty boring), while I am working on the lights. Today, I added a more
robust AC plug for the current supplies. I will dress the wires with some strips of gaffers tape, and neaten the AC runs.

Update: - I am running 15k lux until true leaves, and am planning on 20k lux when I see true leaves and how the plants react.

DAY 1 !!
Less than 36 hours from starting seeds, and 6 out of 9 are above ground. The others were laggards in cracking or producing an initial root, so I will expect leaves in the next 48 hours.
for the sake of notes, I will call today "Day 1", and new weeks will begin at lights on on Mondays.

I am providing 14K - 17K Lux with a single bar of 4 3590's (3500K). Height is approximately 3', with 1 Amp across the bin BD COBs. (I know that PPFD is a better measurement, but I only have a simple Lux meter.)

I do have some 5K COBs, but am spending my 'light' time dressing the wiring on the current build, upgrading hardware, and replacing the breadboard wire connections with solder/heatshrink. I have 1 out of 2 aluminum brackets cut for a pair of 2-ish foot 2 COB arrays for the future.

Food: 5ml Canna base 'A', but 5ml Canna base 'B' + 15 ml Canna Rhyzotonic + 1/2 ml Mammoth P in 1 Gal Distilled Water, Pd'd to 5.75-ish. EC about 0.75

Two plant meristems from one seed. How rare is this? (TGA's Jack the Ripper).

I wish I had left a bit more room at the top of the cup for more coco. I increased the lights to 30k lux yesterday, and that is probably a better starting point.

Never seen that before. It's almost like there were twin seeds inside the shell or something.

Hey bro just had same thing happen but mine are like 10-14 days and Im just letting the grow out like that if they are fem anyway but yea there 2 in one wish all seeds were like that I'm sure u could wait till they got like 10 days or so and separate them if u want

 

[chuckie86]

Here theres the twins of SSD they are 2-3 times as big now

Pretty cool, like to find out more about that

For godsake why 12/12? You know weed plants are incapable of responding to flower induction until they reach a certain age/size right? So what's the point of 12/12 for the first 5 weeks or so, slow growth? Maybe 12/12 from cutting taking, but from seeds? Pointless other than saving power.

The (unintentionally) snarky response is that is what I want to do with my resources right now.

A better response is:

In my last grow, I had great success with mainlining/fluxing 3 blueberry in a 4' x 2' space under 400 watts. See: https://www.rollitup.org/t/blueberry-grow.943394/ Mainlining/Fluxing are going to be part of my repertoire as I go through the beginner stages of growing. It is very attractive to me, because the plants are more compact than a bush, and they are much more portable than a scrog, even in the later stages. This is actually important to me for a good portion of the year.

After seeing this thread on 12/12 from seed:
https://www.rollitup.org/t/the-12-12-from-seed-thread.416589/

I began to wonder if the single cola from 12/12 from seed, might be a good indicator of how well the multiple colas in a flux/mainline will form. My theory is that it is. I am doing the work to see if it is actually so.

Also, since I am growing from seed at this point, nothing finishes at the same time. and the the same strains definitely differ in size and taste. Doing 12/12 from seed will allow me to explore more strains in my 4x2, than 2 bushes. I am more plant-watching than anything else this time, and will educate my palette with the resulting strains. I do not need a big yield this time.

I do intend to become aquainted with scrog and selective leaf picking, but not this time around.

Just checked out that blueberry grow of yours, great job man good work on them

Well at least you can see which ones flower fastest when grown in 12/12 all the time. Could be something good to know. Probably would mean a faster plant from clone too.

Some people have managed to go perpetual with 12/12, but I will be trying something else come January

Thanks Mister Magoo! It was a _lot_ of fun to do!

I recommend 23/1 for veg cycle. Not as hard on plants as 24/0 but almost as much growth. Works great for me, much healthier looking than when on 24/0. Unless power consumption is a big concern and you don't want lights on 23 hours a day.

I'm watching t his..Im interested in 12/12 from start too.

The first week since coming above the soil (coco) has been completed!

I decided to transplant early, (usually do this early in the 3rd week with air pots), as the seedlings were a bit stretched.

The first day or two, I was lighting with 15k and 20k lux at the leaves, as measured by the standard "Cheap Lux Meter" available everywhere. I upped the illumination to 30k, which in my case, is 1.4A into 8 CXB 3590 COBs @ approx 3 feet, or 400 watts. I managed to install a larger current supply on one row, which will allow me to pull about 1.75A, or approx 62 watts/COB, or up to 500 watts over a 2'x4' area.

The 2nd mistake, is that in the first week, I did not add cal/mag. (I use distilled water on seedlings.)

So, I transplanted all of the seedlings into the 8" diameter x 8" (inside height) air pot. For this run, this will be their final pot. I was happy to see nice white tap roots, at the bottom of the party cups! All went well, except for the 2-headed Jack-the-Ripper, which had some coco fall apart during the x-plant. I didn't have the "Medusa Head" root system that I would have had, had I started with a small air pot, and left it for 3 weeks, but transplanting went easier, as you have to take apart the small air pot to transplant. I added a mycorrhiza product from Extreme Gardening during the transplant of 6 of the seedlings. It was much cleaner to handle than the individual black spores that I have previously used.

Feeding: Canna (light) regime, plus a few extras - Switched to aired tap water this week.
* Cal/Mag - 1ml/Gal
* EM-1 - 3/4 cap / 5 Gal (approx 2ml/gal?)
* Mammoth P - 0.5ml/Gal
* Canna A/B - 7ml/Gal each.
* Rhizotonic - 7.5ml/Gal
* Cannazym - 10 ml/Gal
* Water had an EC of approx 0.2.

Total: EC=1.15 PH approx 5.85 (I will probably dilute to < EC 1.0)

I also foliar sprayed with a mix of 5ml Rhizotonic to 1 liter of distilled water 2x/day last week. I will increase it to 10ml/liter distilled water this week.

Below are a pile of individual seedling pics, and a pair showing the difference between a party cup and a small air pot.

The 2nd mistake, is that in the first week, I did not add cal/mag.

You should buffer new coco with cal-mag at a ratio of 20g to 50 liters water. Most of the compressed blocks here work best with 25 liters so I use 60g.
Add it to the water, pH it, then add your coco and let it soak for 12 hours if you can. Drain off any excess water, it should be very little.
Dig up the bottom coco and spread it over the top so the moisture can distribute better., now add perlite, add even more perlite than you thought you need. fuck it can be 2/rds perlite if you like daily work. Oh yeah, befor doing anything, if you have a ppm pen, test the water before and after adding the coco to see how much it rises. Ideally, this will be close to zero. This is a sign that most of the salt is washed out. and the cal-mag will knock off the left over Na and excess K.

Now your coco is ready to start working with. You only need to add a little nip of cal-mag with your nutes. and it should stay in range.

Remember that block pot with the holes is designed to prepare roots for tranplanting, not as a final container, they are probably going to take like 5 to 10 days to outgrow it, but it will be worth it.

The black air pots are awesome. I have small pint-ish sized ones for starting plants. I have been able to start and transplant other non-transplantable plants with them before. I also have the 2 gallons, (8"), which I am using this time, and the 4-ish gallon (12") airpots which I used last run. Roots run to the the edge and air prune. I get the healthiest root systems with them it seems.
