spray it. the plant'll live for quite a while in there, I think everyone will be quite suprised by this.
Oh and U can still water it, just remember that in a smaller sized pot U gotta reduce the amount of water u give it.
make it so that just the top is wet, then in a few days when the water finds its way to the bottom, the top will be dry. let it dry out completely, then water again.
just continue the cycle.
good luck
