There is one thing that beats them and is even cheaper.... ordinary plastic growbags that you take a paper punch to. Then you just need good air circulation around the bags and those roots explode like the spines on a porcupine.

I have also done a milk crate lined with garden weed screen outdoors, but not with cannabis. That holds about 7 gallons of soil.

The air pots are over 10 years old now, and the only ones showing wear, are the ones left in the sun for a couple of summers. I really like how the bottom is open to the air too. The roots search the entire pot in time. I like being able to turn/carry with one hand as well. The final trick is that I can put a tomato cage in it, and it is portable! Great for flushing outside the grow area.

I think that they will work well in an automated water (drip/waste or flood/drain) system too. Just have to remember that the bottom of the pot inside is up an inch or two.

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.
Why use the regular seeds?
Also, are you planning on mainlining your all plants?
I think that would be problematic with a 12/12 cycle from seed.

12/12. 1 cola. No mainlining this run. I used 2 regulars, because I have never used them before, and wanted practice determining sex, before I do a larger run with them. This is more of an experimental fun learning grow for me. ;) I also have never grown anything that was more than 20% Sativa, in an Indica dominant hybrid. Time will tell if I have a half dozen strains in the end, and which ones performed under these conditions.

End of week 2. Except for the originally 2-stemmed Jack the Ripper, everybody is looking good. They have nice growth, especially the two cookies strains.

I added a "pinch" of Yucca to both the ferts, and the 10ml/liter Rhizotonic that I foliar spray with after right lights on. It is supposed to act as a wetting agent. I will continue this going forward. Ferts for week 3 will continue to be Canna (light schedule or less), week 1-3 recipie, +0.5 ml Mammoth P, +few ml EM1 +1-2ml Cal/Mag +pinch Yucca.

There are a few fungus gnats. that I see occasionally. grrrrr. They originated from the bag of COCO that I used. I am putting up yellow sticky paper tomorrow, and have some spinosad (spelling) if needed.

I am continuing the grow, "as if" it were a perpetual 12/12 from seed scenario. It will be interesting to see what the next week or two brings!

Week 3 (since cotyledon rose) is in the books. A large amount of growth and lush leaf on the Kushes, and 6"-8" or so on the Girl Scout Cookies, Green Crack, and Blue Mystic. It is fun observing this grow, not knowing exactly what to expect, and trying to keep it generic as possible. The lure of multiple strains in smallish plants is very strong indeed.
The "mutant", Jack the Ripper, which came with 2 stems, continues to perform genetically bizarre things. I know I will have to off it at some point.
Waiting for sex for everybody at this point. Querkle and JTR are regulars.

Some veg/macro pics: (growth from remaining 1/2 of mutant seed/plant is 1st pic.)

if you have spinosad, i would use it now. that shit is awesome on gnats. in a 1 gallon pressurized sprayer you hit all parts of plants and top of soil in just a few seconds, and has always worked first application for me. usually a few stragglers for a few days, but by end of week, empty yellow strips

I do have some spinosad left over from drenching spring spinach roots about 4 years ago. I ordered some "beneficial nematodes" from Amazon (!!), and if they arrive in the next couple of days, I will add them to the food/coir web, and let them have at the larvre. If that fails, will try the spinosad.
I really want to give the nematodes a go, as I can use them in preventative pest management for all future cannabis and vegetable grows.

My first time sexing a regular. I would venture that this Querkle (TGA) is female, based upon the appearance of white hairs around the 4th node. No sacs. Feedback welcome!

Predators will never kill all the prey, or they would run out of food.
that is what I have heard too. spider mite predator packs actually come with spider mites in them as food. It is best for outdoor areas/greenhouses where you would never be completely rid of bugs. Indoor bug free is the goal to most grower.

I am going to read about preventative pest management, as I know that I know very little about it.
I did a soil drench at 2 teaspoons 0.5% spinosad in a gallon of water/ferts, and sprayed the top side of the leaves. I think the recommended amount is 4 Tbs/gallon, so starting light. I have only ever seen fungas gnats, and saw that they came with the pre-packaged bagged coco from Canna. I have only seen them before when starting tomatoes indoors with FFOF and a local potting mix. I will probably go back to using compressed dry blocks next time.

Week 4 is over.
I increased the nutes, according to the Canna schedule, to about 650 ppm, including the tap water.

I added a very weak root soak of Spinosad early in the week, and a day later, the Neamatodes arrived on ice. I don't think that the Spinosad killed the Neamatodes, as there is a huge reduction in newer Fungas Gnats.

I tied over the Blue Mystic - it was the tallest. I took off the top 2 leaf sets on the Green Crack and the Girl Scout Cookies.

Sex on all! The Querkle proved to be a female early in the week, and I think I see the signs on the Jack the Ripper this morning. Green Crack, and the Kushes win the beauty contest, and the Green Crack is showing nice pre-flowers.

Some isolated veg shots.

Blue Dream, Blue Mystic, Bubba Kush, Cookies and Kush, Girl Scout Cookies, Green Crack, Jack the Ripper, Gc top, Querkle, Zombie Kush.

Blue Dream and Cookies/Kush look a bit weak. The mutant Ripper as managed to put 2 sets of normal nodes together back-to-back.

Week 5 (from cotyledons) completed.

Much growth and flowers forming. The sativa's/dom's (Except green crack and the mutant Jack the ripper.) and the Bubba Kush are 3 feet tall. The rest are about 2' tall. I took down the Cookies and Kush plant, as it doesn't look like it will produce. Flowers forming elsewhere. The Green Crack looks especially nice. I have never taken a clone, and I tried that last week. No roots yet.
The lights are at different heights, with the taller plants under the raised 4' bar running 1.75A, while the lower bar is at 1.4A It is approx 50k lux across the tall plants, and 40k-50k lux across the smaller plants.
Temps are lower this week. 69-72 degrees @45%-50% RH, compared to 78-82 degrees F @ 55-60% RH last week.

Week 6 (from cotyledons) in the books.

Flowers are developing. I will increase the Canna ferts to 900 ppm with pk 12/14 in week 7. I managed to break the blue dream top while supercropping it. Now, there are two tops growing. I have supercropped a lot of the taller plants to try and hold the 3' mark. This is the first time I have grown sativa, and am fascinated watching the Blue Dream, and the (mutant) Jack the Ripper buds form. The Querkle is the smallest plant, and is on a milk crate. Very pretty. The Girl Scout Cookies is tallest plant at the moment (supercropped once). The Green Crack is growing like an Indica, which surprised me. Looking back at the seed source (Seed Supreme) it appears that there is more than one Green Crack, and this is indeed indica dom.

I am not expecting large yields, as I have been pretty much letting the plants grow naturally. I am certainly not going to be seeing a lot of single colas, as there is much branching on all plants. I am thinking a method to get the single cola small plants might be to take a clone of a sexually mature plant, and almost immediately place it into 12/12 once some roots form in the soil.

The clone experiment seems to have gone well. (Just gaining experience doing something for the first time.) It took about 10 days for roots with the OxyCloner and tap water. I transplanted into coco with about 1/4 strength nutes. Hopefully, the plants will take. I took clones of the Bubba Kush, Blue dream and an unremembered at various sizes. 6/6 for producing roots.

Some photos from last week, at the end of week 7 of 12/12 from seed.

The plants finished a week at 900 ppm with a PK boost.

The Blue Dream and Jack the Ripper are going to outgrow the lights, and produce very modest flower. The first time I have observed Sativas.

Some pics after week 8 (from seed), and some observations.

The clone experiment: I took 4 clones (my first time doing this), and have 4 small plants in Solo cups. I topped them when I put them into the OxyCloner (tap water), or later, when they went into coco in a cup. All of the original leaves are still present, and new (small) growth is coming. I see roots at the bottom of the cup as well. Bubba Kush is dense and bushy. The very small Blue Dream did well, and the unknown one as well.

Zombie Kush: This plant has the most frost on it at this point, and has the whitest pistil's.

Blue Dream and Jack the Ripper. The Sativa (Dominant) strains are tall with fluffy buds. Jack the Ripper has more flower at this point than the blue dream, but the blue dream has more branching. The blue dream also (accidentally) lost its' top a couple of weeks ago.

Bubba Kush: The greenest leaves and nice calyx formation on the top bud. This plant is also capable of consuming ferts at a higher level than the others. Tips are perfect after the pk boost week.

Green Crack: Boy was I surprised to find this growing like an Indica.

Girl Scout Cookies: This plant has the largest main cola, and the thickest stem. It is also taking up the most space, and is drinking 2x the water/ferts as the other plants. It has many branches, which tend to leave the plant at a 30 degree angle, instead of a more typical 60-75 degree angle. I am sure that this plant would be an above average choice to run in horizontal in scrog. Opinions?

Blue Mystic: Short, squat plant. The notable feature is the size of leaves coming out of the main cola. (very large).

Querkle: This is the shortest and squatest plant. It is only a sample size of 1, but if it is representative, it would be a great plant to grow in a small space, assuming you like the smoke.

Problems: I know that my Canna line ferts is pretty stable BUT, I have been adding to it, and I recently measure the PH about 2 days after I mixed 5 gallons, and was surprised to see how much it dropped. Basically, I run the entire Canna line, using the 'light' schedule, with tap water, and have added the following: 1-2 ml/gal cal/mag, 0.5-2.0 ml mammoth-p.
Recently, I have been adding OM-1, (about 1-2 ml/gal), about 1-2ml/gal of molassis, and about 1/4 teaspoon of yucca powder. For the next batch, I am going to eliminate the last 3 items mentioned, and re-establish that the rest is still indeed ph stable over time.

The 2nd problem is that my work schedule is changing a month earlier than expected, and it will be hard to finish/flush/trim/dry/cure the plants with the attention that I like, as well as establish the winter garden. I have found homes for Jack the Ripper and the Blue Dream should that be the case.

I am also at my plant limit, exactly. I would love to carry the clone experiment further, and if I had a clone of the Girl Scout Cookies, I would grow/clone that, and make that my winter run; I don't, so they will go to the compost pile this week. My next run will probably be 4 Alien Rift (regulars) in a 4x4 scrog. I have never done a scrog before, so it is part of my education.

Some assorted pics below:
