The growbed is ready to be moved into position and filled with rock. Tuesday night, I installed 1″ foam insulation board on the inside surfaces. This changed the dimensions to 36″ x 91″ x 12″. (area: 22.75 square feet or 2.1 square meters; volume: 22.75 cubic feet or 170 gallons or 644 liters). Tonight, I installed the pond liner and the drain. Turns out the pond liner is cut a few inches bigger, so I had enough material to fold over the top edge of the growbed sides.
