So you wouldn't flush at the end either? I kind of did the same thing my first time, just gave it ph'ed water at the end to at least flush the soil out. It's funny people go spend tons of cash on building tables and stuff when in all reality most of the time you can get away with just watering the plant enough so that it doesn't come out the bottom. That said, obviously flushing them out is preferable and makes for a smoother smoke.
