It's hot in Phoenix Male
Default
Pore opening in crassulacean acid metabolism plants depends on light presence or absence, and absolute temperature. If it is dark and the temperature is correct, pores open. It doesn't require a day/night difference. My understanding is almost no crassulacean acid metabolism plants open pores at 30C/85 F and above. Many plants suffocate below this night temperature, however. It varies from species to species.

Can you open windows at night?
