I usually wait until it is really dry. When soil against the pot is not touching it anymore. Crusty dry, but not for a week! 1-2 days MAX. When I see it's crusty dry, I put 3 liters of water in a container and let it sit there for 24h. So next day I water it.

It depends on the plant itself! Mine likes hot temps and cold dosen't harm her. She likes being thirsty like a lost man in the desert! But she is touchy for nutes..She dosen't like too much, and too low she will yellow fast.

Know your plant!
