My buckets runneth over

Ebb and grow went a little bad here. I think the root growth is gobbling up volume all over the place, and now I'm soaking the floor.

I know the solution. Buy some dinner plates at the dollar store and elevate the buckets so that the water level goes down a bit.

However, it's interesting how it happens mostly in the morning. Perhaps the girls haven't woken up yet? Are they late sleepers? My theory is that they're not metabolizing much until they start getting that light. Am I right?

Thanks in advance.
