12/12 From Seed Experiment - 21 Strains

[Hot Diggity Sog]

And of course they will be grown 12/12 (if only to determine the sex of the bagseed quickly) along with a delahaze and lemon kush (when my order arrives). I've done a bbgum on 12/12 before, not a great yield but lovely smoke. Your experiment has inspired, thanks man

That's very flattering...thank you.

Just keep doing what you're doing looking forward to seeing your results

Day 59 Update - Day 34 Flower
Strain #3: Barneys Farm Seeds G13 Haze
21" Tall. All of the lower shoots were removed at or around day 21.
This plant has a large number of sugar leaves.


I decided to continue with defoliating this one...I remove most of the larger fan leaves but did not touch any of the sugar's.
Here she is right afterwards.




Strain #5: Barneys Farm Seeds Red Dragon
21" Tall. On or around day 21 the lowest side shoots were removed.


Starting to get some violet colored hairs which is cool and is due to the Metal Halide.

Edit: I have a 100 watt incandescent light turned on and I think it caused a lot of these leaves to look brown and dying which is not the case at all. Everything is lush green still.

Day 60 Update - Day 35 Flower Part #1
Tonight was the big night to pull all of the plants out of the tent and do the big rearrangement for canopy evenness. I noticed one the plants had what appeared to be a deficiency which I figured was maybe nute burn. I posted this picture on the Problems forum and the guys said it looks like mites. My heart sunk...I'm really scared now and the lights just went off so I can't check with my loupe for 12 hours.



This is the only plant out of the 35 or so plants going that looks like this. I'll be googling tonight but if there is a solution in the event this is mites, please tell me!

Day 60 Update - Day 35 Flower Part #2

This is the 1st time I have had the plants out of the tent since I moved em in so I got some pictures with them being nice and spaced out.

Day 60 Update - Day 35 Flower Part #3

I have a very large variance in height. Shortest plant is 16 inches and tallest is 44. Here is what I've come up with:

I organized the plants into 4 groups according to height. These plants have not had their risers put on yet to even them out...this is just the 1st step.

I decided to put the shortest plants in the right rear. The milk crate they are in is elevated by a 1/2 size milk crate:



Side angle:



To the left of those, I put the 2nd shortest group.





This shot shows the 1st two groups and how they are elevated:

Groups 3 and 4...the tallest plants

Day 60 Update - Day 35 Flower Part #5

Putting it altogether, here is the updated tent.



I still need to implement risers on each plant to bring them up to the correct height but since I have organized them into the 4 different height groups, this task will be much more manageable and I will post updates on how I do it and the end results soon.

Watering is now going to be more of a pain because I don't have drain pans underneath to catch run-off but such is life.
I'll just have to pull each of the 4 groups out one a a time and water over a tray. With only 25 ish days left that's fine by me.

 

[Mainlinekush]

I have the same
problem after tent is loaded I pull 6 pots out and water them outside the tent. Then crawl in and water last 5. Whole time I swap regular catch tray for large oil pans so I can dump run off before putting plants back into position takes over an hour about 8 gallons of water get used.

Day 64 Update - Day 39 Flower

Problems galore. Up until a few days ago, this experiment has more or less gone without any major problems. On my previous update I had shown a plant with what appeared to be mites. As it turns out, it was not mites which is great. What it ended up being, most likely, was PH problems. This is is such a rookie mistake and I'm really upset at myself but here is what happened.

For the 1st 40 days or so of this grow, I checked PH after mixing nutes religiously. My tap (well) water was always right at 7 and after adding nutes it was still at 7. I gradually got into the routine of adding 6.25 ml of PH Down on every 5 gallon watering. I got lazy and stopped checking PH. On Day 22 of flower is when I really started increasing the feeding schedule and I made the false assumption that the nutrients were not affecting the PH. As it turned out, my feeding regiment during day's 22 thru 33 of flowering was bringing my water all the way down to 6 before adding PH Down. So I have been watering with water that was approximately PH'd to 4.8. So...this sucks and I hope I have not done too much damage to both quality and yield.

2nd big problem: My carbon filter inside the tent has failed. This problem started about 2 weeks ago but got really bad within the last couple of days. I've checked for leaks so the filter has either faltered or humidity has affected it. Filter is only 70 some odd days old and RH is consistent 46% to 54%. I've order a replacement and will have it Friday.

My secondary line of odor control is holding up for the time being but it's a little nerve wracking.

4 days ago I flushed HUGE amounts of water thru the pots.
Yesterday I watered with 60% strength nutes + 4 ml/g of Cal Mag and only 2 ml total of PH Down.
Today I watered with 70% strength nutes, no cal mag and no ph down.

I chose CalMag on yesterdays feeding on the outside chance the deficiencies I saw were Cal/Mag def. and not PH but that is unlikely.
Either way, I did a low does feed of the cal mag.

Plants are looking nice still and a follow up update is coming with pictures.

well im gunna skin up put the kettle on and read through this because im doing 12/12 from seed now and r trying to master the one cola thing. i plan trimming off the side shoots from the bottom until it starts to go into flower giving just one cola.
iv done it before its simple it takes no space and if you get a problem its only in one plant.
its good for a constant harvest.....good luck if im not to late iv not read any yet....peace

Day 64 Update - Day 39 Flower - Part #2

I put the HPS back in. Canopy has been relatively evened out. One more re-arrangement coming and then the make shift net will be applied to prevent toppling over.

Some of the milk crates pulled out and photographed in the dark:

Doing a grow like this is a great way to learn about the plant, and different strains. I learned a lot with my limited 12/12 grows.

thats one of the reasons i do it

Closeups! These girls are really packing on the resin. Wish I could do my camera justice. I'm a terrible photographer.

Welcome and pull up a seat! If you have any questions feel free to ask. If you have any suggestions, please don't hesitate!

Day 45 Update - Day 20 Flower

So after being very disappointed with the experiment on my last update, I am starting to feel a little bit better about it. The tops are continuing to grow with alternating nodes and it looks like I will end up with some modest colas.

The two Critical Jack Herer - Critical Mass x Jack Herer plants are not only the tallest and most stretched plants but they are also the slowest to get into full flower swing. I really don't want to remove these two but if they continue to get taller I will have to.

I'm posting a picture of the canopy from inside the tent...it's HPS so sorry!
Picture #2 - Barneys Farm Seeds Critical Kush - Critical Mass x OG Kush
Picture #3 and #4: KC Brains Northern Lights Special

Thus far there is absolutely no difference in plants potted in 3" pots vs plants potted in 4" pots.

Going to do some defoliating this weekend. Will post before and after's.
A big flush tonight and then starting on Week #4 nute schedule @50% strength.

thats what mine looked like but with out the stretch.......light ultra close worked for me......looking nice

I kept the light ultra close too. I think the consensus is that the tightly packed spacing was probably the cause. Up thru the stretch, 16 per sq/ft with the 3" pots and 9 per sq/ft with the 4" pots.

Day 67 Update - Day 42 Flower

Things are going very well. I stopped feeding for a few days and am watering with only PH'd water. The girls were not burned but they just looked like they had too much Nitrogen. After this flush I will resume feeding but I will reduce the high Nitrogen portions of the feed and increase the Bloom. Thinking maybe 30%-40% for the high N and 60% - 70% for everything else.

Odor management is no longer working for the tent so I just replaced the carbon filter with a new one. Sure hope it was a failed filter and this works.
Otherwise, not too much to report. Girls are doing lovely. A few of them look like they are going to take a long long time to finish. Once I hit around 52 days I will start taking a loupe to them and will check trich's daily.

Here are some random closeup's from different plants.
