Temperature is probably the most important aspect of your grow room. It controls the metabolism of the plant. (one of the things anyways, but the most dominant thing).
Ideal plant conditions with CO2..
Day time up to 90 but I have my ceiling set at 87. high temps and low humidity (flowering) is really hard on plants. The less the difference in day/night the better. With my de-hu running it gets to like 79 in there. Getting below 70 at night will slow down the metabolism of the plant which sloes down everything. So in essence, don't let it get below that. Night time is a VERY important time for plants. Also, cooler temps at night creates stretching plants and nobody wants that.
Higher temps and humidity with hydro. Probably, high temps means faster metabolism and high transpiration and therefore more water vapor in the air.
Without Co2.
Co2 is the first limiting factor as metabolism increases. When the temps get above 76 or so and you have strong lights the plants want to do everything faster but they can't..cause they can't "breathe" because there is not enough Co2 in the air. So photosynthesis slows down. I don't know if it cycles back and forth or it jsut slows down by I suspect the former. Kind of sputtering in fits and starts. The co2 in the leaf boundary layer is depleated, photo stops, it is replenished, and it starts again.
ok? ok.
