Oriental greens - the outrider experiment
YAY! Evergreen Seeds finally shipped my new weird greens seeds! I hope everyone was alright there - I ordered Oct 15, but they went on a two-week shipping hiatus.
Getting rather a lot of oriental greens seeds, because they had a minimum order size, and cheap seeds:
- Asia red amaranth
- tender leaf green amaranth
- hybrid senposai (hybrid of cabbage and komatsuna!)
- kojisan komatsuna
- Korean red curl lettuce
- hybrid bimitas lettuce
- Chinese fragrant choi lettuce
DrAnn turned me onto these (I'd been looking for komatsuna - one of the odd greens I really loved from the mesclun kit - and got really interested in her amaranth). Her outrider system for growing greens was what decided me on getting a Deluxe instead of a 400W grow light array next. I want to try starting these in AG or Park Starts and grow them in hydroton rock hand-powered-ebb-and-flow containers, in the Deluxe's spillover light.
And they come soon now - yay! Now need to decide which to grow first. 
Week 1: Coming along nicely. Seedlings germinated nicely alongside the pro100. Still too small yet for stronger nutrients or moving to individual pots yet, I think. Only the fragrant choi (lettuce) has visible roots yet coming out the bottom of its sponge. So it'll probably be the first to move. But no need to move any before first true leaves, I think.
Since the labels are cryptic - this is, from left to right, red amaranth, fragrant choi, senposai komatsuna, kojisan komatsuna (same order as the seed pix upstream). I put about 4-5 seeds in each pod. Not sure why so few of the komatsuna sprouted. I've been draining and refilling the container most days at least once (lift upper container to drain, then plonk back in lower container to sink & refill). But there's not much need at this stage - only the bottom of the pods reach the liquid, so the baby roots get plenty of air.
This is a great little experiment, using the hydroton rocks.
Everything looks good, you are even keeping that essential air gap. Watch out for algae growth though, is that container light proof underneath and at the sides? Algae, being a form of plant life, loves to grow in your nutrients when exposed to light, it will not grow in dark conditions.
The algae will use up your nutrients, it will bloom and decompose. When it decomposes it releases toxins into your water, these provide a food source for pathogens, fungi...
Not wishing to scare you though. 
Looking good, and these are just laying around your AGs, huh? Nice, Maere's ready for lettuce so guess it's time to get some going around the AGs and maybe in the tent, how much temp can lettuce take without bolting?
is that container light proof underneath and at the sides?
Well, you can kinda see in one of the top pictures. The inner container is frosty translucent white, so you can see roots and rocks fairly well through it. The outer container is yellow frosty translucent. Both together, you can't see through very well, and only dim yellow light would get through. This is only a cradle arrangement, though, til the seedlings get big enough to put in separate containers (might put two in one...) Drann seemed to think it important to be able to see through enough to see the roots and water levels, and then darken the outside. When I move them to their own containers, they'll also have rocks up higher (though not the liquid level), to cut down on light. For now I want to be able to inspect / remove them easily.
But yeah, I got that part. Cut light, cut algae.

Yeah, just sitting next to an AG. I grow seedlings in Park Starts blocks that way all the time. Haven't seen how well the whole plant grows under those conditions yet... But that's one of the growing-lettuce-in-summer strategies, to grow cucumbers on a lattice above, and lettuce in the shade below. I imagine they grow slower that way, but they seem to not be terribly light-demanding. Anyway, Drann says she's done it, and I wanted to try reproducing this.
Because I want to grow lettuce and ornamentals all the time, but also want to try other things... Like peppers, eggplant, and tomatoes.
I grow lettuce in my kitchen, which is frequently up to 75-80 degrees. The lettuce grows. It just won't last long - maybe 2 months before it's too gangly to bother with anymore. Lettuce heaven is more like 60-70 degrees. Then, it'll stay productive... 3 months? Maybe a bit more. Depends too on the variety of lettuce. Romaines (cos) supposedly do better, and all the lettuces in this bunch of seeds were "all year mild climate" types, and I have a "heatwave" collection (that doesn't stand up to summer, but handles 70-80 degrees for a while.)
If you send me your snailmail address, I could mail you some "heat" lettuce seeds to try - your pick of the above, or this one. The latter I've tried - they're good.
Peat's point was well taken... Moved a very long digression to topic But We Digress...
Please note that moving comments involves me hand-editing the database. Try not to digress...
Week 2 (almost): decided it was time to move the fragrant choi and komatsuna to their growing containers. Actually, the senposai komatsuna isn't quite developed enough yet (true leaves barely there, roots not out of the sponge yet), but I wanted to put it in the same container with the kojisan komatsuna - close enough. The kojisan and fragrant choi have persuasive true leaves and roots coming out of their sponges.
The original intention was to grow these as outriders to my Aerogarden Deluxe, currently growing mini bell peppers. But... that spot by the bedroom slider, with winter coming on, is chilly. I had been growing a spare pepper plant there, but it was dropping its flowers on cold nights, and I know from seedling starting last spring - it's often below 65 (or below 60...) under that window. That part of my bedroom juts out above another balcony, and the window's none too well insulated. Brrrrr. So, the potted pepper is taking up a lot of the Deluxe's spillover light space now. And komatsuna and lettuce should be perfectly happy with a low-lit cool spot.
The weak sunlight is augmented by a $10 Walmart grow lamp, attached to the window with suction cups and hooks. They also sit in a bit of reflective blanket draping, to bounce light back onto them.
The nutrient broth is the same General Hydroponics lettuce mix worked out from BB and Peat - 6.3 ml hardwater micro, 10.6 ml grow, 2.1 ml bloom, in 1 gallon water, half and half Brita-filtered tap water and distilled.
I've had a terrible time growing brassicas (komatsuna is a brassica, like mustard, and almost all the "baby greens") with Aerogarden kits. But in my current mini greens garden, the mustard - which was stark yellow and dying on AG salad nutes - has turned lush and green, and even the stray komatsuna in a mesclun kit pod in the pro100 is growing happily. So I think they'll like this mix. The komatsuna got transferred to a full mix a little early, but it's been my experience that lettuce needs to move from "starter" to "growing" nutrients at about 1.5 weeks from seed, not the 2 weeks the AG kits go by - it gets very yellow the last few days of that regime. (Note how yellow the fragrant choi is, compared to the komatsuna, above.)
I've never grown amaranth before. No idea whether it's struggling or just slow.
Looks OK.
Gisette, now you are doing this method of growing - you may not realize this, but you have opened yourself up to a different world of hydro... subterranean growing...
You can grow such things as carrots etc using what you are doing with your containers, albeit using perlite instead.
If you are interested I will go into it further. 
Huh! That is interesting, Peat! I probably wouldn't grow any root vegetables (they are cheap), but sure, if you'd want to start another topic on how.
For now, I'd just like to secure an external salad supply to release an AG to grow other things.

Week 0: Planting day!
Planted 1 pod each Asia Red amaranth, Fragrant Choi lettuce, and Kojisan and Senposai varieties of komatsuna. (Looks like my mesclun pods in the pro100 have a bit of komatsuna too. Yum.) Komatsuna tastes like mild horseradish, though the senposai is supposed to be a cross with cabbage. Kewl. Fragrant Choi is supposed to smell like jasmine. I have no idea what amaranth tastes like, but it's edible and looks as gaudy as my coleus.
The seeds (these links go to EvergreenSeeds.com):
The original intent was to start these in the pro100, but the seeds got delayed a couple weeks. Then I figured I'd use a Park Starts block, but eh. The Deluxe came with a new-style Master Gardener kit, with the new biological-laced spongy peat moss plugs. So using those, plugged into hydroton grow rocks. Stacking plastic containers. I used a soldering gun to drill holes in the top container and stick the labels on flap-style.
This is just for sprouting. When they're established, probably only one or two pods can go in that little container.
For nutrients, used the same mix I'd whipped up for the Park Starts block on the other side - Flora series, 1/8 teaspoon each (~0.6 ml) micro / grow / bloom in a half gallon (2 liters).
Wish me luck!
Oh, and if Ann is reading this - please let me know if you see anything wrong with my approximation of your scheme!
