In a local kids museum the display is a 20 gal. tank w/ plastic lid,
w/ holes in it. This sits inside a display box made of plywood and
painted gloss black. The front is mostly open, except you can't
get access to the plants from the front. The top hinges open and has
a padlock hasp on it. The light fixtures are bolted on the underside
of the lid, and the lid has two vertical slots the full length of
the cabinet for air circulation.
