 But the difference is that rather than just scattering the light, you're converting sort of some of the useless light. Yes, so the coating is on the outside of the greenhouse and it's taking UV light and it's turning it into red light. So it's increasing the amount of bright red light inside the greenhouse and that should help these tomatoes grow better because obviously these plants are green, they photosynthesize, they use a lot of red light, that's what they want. So that's what we're trying to give them.
