Tiny cactus, again

Remember last winter, when to help fend off the I-can't-do-much-gardening doldrums I planted some cactus seed, and raised several tiny cactus? It certainly was fun and interesting, but as you may also remember I ended up giving those spiny seedlings away -- they were not cold-hardy varieties and I don't have room for overwintering more indoor plants. Especially the potentially painful ones.

What I didn't tell you is that last spring I ordered some cold-hardy cactus seeds, and a few months ago I sowed them. Here's an update on a project that you didn't even know was taking place.

I have no idea what species I have here yet, but they definitely look different than the previous batch. I've got at least three different varieties here.

I suspect I'll be able to identify these once they get a bit larger.

I think there were about 15-20 seeds that I sowed, but only about half a dozen have germinated.

So far that is. I suspect some of them may take quite a while to wake up -- a year or more!

I believe this one just recently germinated:

I'm not sure how long I'll leave these in the little tray they call home, as it doesn't have drainage holes. It definitely can't go outdoors as-is.

For a sense of scale the inside of this tray is about 5" (13cm) wide.

Perhaps I'll just drill some holes in it -- might be less traumatic than repotting each of these. We'll see though.

So I've got small spiked seedlings to care for again. Fun!

I wonder how large each of these will eventually get?
