It is very concerned about CIA mind-control rays. Also, this is a relatively easy way to keep it mostly in the dark.

So this is the same feeding method 3, foliar feeding by submerging leaves in sugar water. I'm using plastic wrap to keep dust out of the sugar water, hopefully slowing the time it will take for fungus to take over, and it also holds the leaves down.

The plant has seemed pretty healthy, like it was growing well, despite the submerged portion (maybe just the new growth?) turning white, so I've decided to take it dark by covering it in aluminum foil. It's not perfectly isolated from light, but if it grew a fat onion bulb this way, I'd be satisfied that it would grow in total darkness from this sort of leaf-immersion foliar feeding (of course, I'd set up a more strict demonstration).

This was a green onion from the grocery store, so the bulb is still very small. I'd say it's smaller now than when it started (I think it has been spending stored energy to grow). I think it has been putting its energy into growing roots and leaves. I did not sprout the roots before planting in soil, and I can't really observe the root growth easily because it's in soil. Keeping the roots in water would probably have been smarter.

I'll miss this cheerful little plant growing in the light. It was funny, reaching all around, in every direction as it grew.

Incidentally, green onions are really easy and cheap to grow at home. You don't even need soil, they will just grow with the bulb in some water, if you put them by a window. You can pull leaves off, and they will keep growing. Nutritious and tasty greens and herbs are often easy to grow with little light or space because of their low energy content. It's a shame that people with empty windows ever lack fresh vegetables because they think they can't grow anything for themselves in an apartment, or during winter, and think of fresh vegetables as expensive.

Maybe someone else would like to do a project of cheap garden curtains. Really get the cost down and convenience and attractiveness up, try to make it interesting enough that everybody hears about it. I wonder what already exists along these lines. I've only really seen herb-garden kits, but I haven't done much looking...
