a porous growth medium supported by the vertical surface;
a watering trough arranged along an upper edge of the growth board, the watering trough having water distribution holes for distributing water to the growth medium;
a water collection trough arranged along a lower edge of the growth board to collect water draining from the growth medium, the water collection trough having a valve that is configured to open and permit water to flow out of the collection trough when the valve is an open position and which prevents water from flowing out of the collection trough when the valve is in a closed position, and
