Gotta install the ebb & flow system.
Drill holes into planter,
install drain spouts,
make hole in wood for drain spouts,
cut out intake holes to provide more intake.

The last thing on that list was done because our negative pressure was too high and we had to leave a flap of the door open to provide extra intake. Now we shouldn't. It's not pretty, but I dont have a jigsaw.
