When plants respire do they use the waste co2 for photosynthesis?

The co2 for photosynthesis goes thru the stroma i.e. holes on the leaves. I do not believe the co2 from respiration can go directly.

If you mean CO2 given out during respiration, then I think not.
tell me........

A small amount of the CO2 produced through cellular respiration at normal parameters(about 1-3%, depends on the book) is used in photosynthesis because it is taken by the cloroplasts while it is still in the cell and taken by green cells on it's way to the stoms

In high-school they teach you that it doesn't. And that is what most teachers know and expect you to say. But, as usual, things are not that simple

:?: Hummm Water on the leaves with lights off can greatly increase your chances of mold, mildew born problems. Plants don't procces the water during periods of dark as efficiently as they would when the light is on.

Misting at the beginning of the day allows the plants to use the water during "Grow time." This also allows you a few minutes to run around your space and mist to your hearts content before you HID reaches high temps. Any over spray (Which should always be avoided) is easily evaporated evenly as the bulb warms.

Misting is also a great way to offset fertilizing mistakes. It increases the leaching of nuts from the plant material.
