youll get it less water is better than too much, dont worry about it. wieght of the pot will tell you,when it feels light water.nothing is gonna happen fast,they will droop from no water but it takes longer than u think.
Be careful running that central air duct to your room. When the air isn't running, and assuming your going to have a constant exhaust, your central air might never shut off. I've seen this happen multiple times. Your exhaust will just suck all the cool air from your entire house through that vent.
