The green light gets deeper into the leaf, gets lower into the canopy.

So it is being used.

It's just that it's not being used as efficiently.

On its way in.

What plant was it?

Do you remember?

And then were you growing it in like a chamber where the only light source was below it?

Oh, that is interesting.

Because I've grown peas upside down and I grew tomatoes upside down.

The same thing happened, but my experiment was not one in which there was a controlled light source at the bottom.

So it was just outside.

But it did basically, gravity was pulling it down and then it kept pulling itself back up towards the stronger light source.

So it was almost this weird stair-stepping type effect.

I mean, I honestly think you just can't.

You're right.

Regolith, that's basically dirt, right?

And the difference between dirt and soil is soil is dirt plus the life that you talked about.

The microbes, the fungi, the bacteria.

And so if you can't do that on the moon, well, first of all, there's no oxygen.

There's no atmosphere, right?
