Homesteading on the Moon with Kevin Espiritu

You know, we sort of cherry-picked them from around the world in all these different environments where they adapted to.

Just get that corn, baby.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Just grow that corn, you know?

StarTalk Radio

We might need to go into GMO.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

All right.

StarTalk Radio

So if you think about that, like take that spinach.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

I don't know where it's endemic to, but regardless, wherever it evolved, it was low in the canopy.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

It was low in the entire sort of hierarchy of the plants around it, right?

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

So it was basically fighting for photons to photosynthesize with.

StarTalk Radio

Whereas a nice tall banana plant or something like that that's growing in the tropics, it has no problem with that.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

So of course it can tolerate more.

StarTalk Radio

And what ends up happening with a shade plant that gets too much sun, if you put it in the wrong spot, is what once was good, the light, actually starts producing more.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

I forgot what it is in the plant, but basically it starts producing too much of a certain compound that starts damaging the plant's ability to photosynthesize.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

So basically too much of a good thing.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

I mean, I wouldn't go as far to make a bold claim to say like all of them would do better under normal sunlight.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

But I kind of do think that's the case because there are studies that prove not only do plants use far red, so like above the 700 nanometer range.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

Yeah, I mean, yeah, you're right.

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

The first sort of LEDs that came out back when I was growing cucumbers, Chuck, back in my old place, they came out and they were called like blurple lights, blue, purple, red, because basically...

StarTalk Radio
Homesteading on the Moon with Kevin Espiritu

whoever was designing them back then was like, well, plants mostly use light between 400 and 700 nanometers, kind of like the visible spectrum.

StarTalk Radio

So they'll use blue light for vegetative growth.
