Grow a tray of micro-greens - PEA BB garden.sand.microgreens

Speckled pea microgreens, grown in a reused takeout container with several holes drilled in the bottom. I'm not sure if there is a minimum quantity? We just started growing these in February, have grown probably 6-8 small containers like this (roughly 1/4 cup of dry seeds).  Highly recommend these to anyone wanting to give microgreens a try, they're easy, fast, and delicious on a variety of foods (or even alone)

I had a bunch of buckwheat seeds for a cover crop, so I decided to try using them for microgreens as well.

There's a lot going on in this mix so I hope they're not too old to sprout. Adzuki bean, alfalfa, broccoli, garbanzo, green lentils, green pea, mung beans, onion, radish, Red clover, and wheat
Edit finally got true leaves, but I've lost so much crop I don't think I can make a salad... Maybe in place of lettuce for a sandwich.

So the requirements doesn't tell how large that tray has to be. So I can have one small tray of mixed salad greens (f.e.) and that's okay for this BB?

Added later: still no answer. But today I started a (small) tray of chickpeas for microgreens ...

Requirements:
Grow a full tray of greens in an inert medium with only water.
Grow to harvesting size.
Maximize reusability of non-plant materials used.

And so I did. A friend had a bulk bag of chickpeas, she gave away 1 kilogram to anyone who wanted. That included me.
To know if the were good to use as sprouts/microgreens I first tried a few:

You see: they sprout very well!

So now for the BB.
First my materials:

From left to right: waterer, bag with potting soil (organic), 'tray' (it contained ice-cream before) and jar with chickpeas.


I put a layer of soil in the tray, made it wet and covered it with chickpeas.
Then I put it in the kitchen windowsil and covered it loosely with the lid.

And then I made a photo almost every day:

Right after that last photo I started harvesting. So that's it. Harvesting size (in my opinion).

Okay trying this one again! I'm using a teavaplanter as my tray/inert material. So my "tray" is tipped on it's side and rolled into a cylinder. Water fills the inside and slowly wicks out to the seeds/plants, the higher on the planter the less water as evaporation and weeping lower the water level. The instructions show 2 "different" ways of starting seeds. 1st seeds like chia that create slime being soaked and then rubbing into the cells. And 2nd ager creating slime you mix "dry" seeds with. I soaked a Tablespoon of chia and smeared it on then the next day I pressed wheat into the slime as high as was sticking. Several days later I have 3in long wheat on the bottom half and 1/2in chia all over.

Once I growed microgreens (see the chickpeas for which I got the BB) I got interested. In a newsletter I get monthly (on healthy and local foods) I read about a set including 3 trays (1 with holes, 2 without), 1 block of dry coco-coir and 4 sachets of seeds. I ordered it. And started experimenting.

Before I really knew what to do and how to do it (I only watched one video, the one above this thread) I started, sowing the 4 different kinds of seeds in 4 parts (next to eachother) in that one tray (the tray with holes is inside one without holes and the other serves as a lid for the first few days. I did not forget to soak the peas and sunflowers in water before sowing. But I didn't realise that broccoli and radish grow much faster than peas and sunflowers ...

Anyway, after about a week I harvested the broccoli and radish microgreens. The peas and sunflowers came about a week later (now). Next time I'll do it different (there's still plenty of coco-coir and seeds left). But I already enjoyed a lot of nice microgreens (over my sandwich, soup, etc.). And today I can eat a 'peashoots and sunflower salad' as a side-dish for dinner.

Green lentils. Soaked them in water for 12 hours and kept under a lid a few days to ensure quick sprouting. Probably not needed but it worked very well. The medium is potting soil which will go into some pot or other on the balcony after this.

I just took a tiny harvest to taste them, they could stand to grow a few days more and get a proper set of true leaves. The flavor is much better and more complex than I expected!
