I keep my mothers in 5 gallon buckets they have about 100 holes drilled for drainage. There is a second bucket that catches the run-off water. If I put a 6" net pot in the bottom of the catch bucket it would be close to the idea of KBS growing. Put the air stones in the bottom bucket and let about 6 or 8" of run-off water hold in the catch bucket.

That is what I was thinking just to be clear.
