i would say 6 hours a couple till it was discovered and then the time to pump it out.They look good a viverant.What i am gonna keep a eye out for is mold.But this has happen before(minus the plants). I have good air circulation and it is quite warm and dry.So thing dry out fast.It was also all rain water. It is cold so i will start the wood burning stove in the basement that should dry thing out.
