Times have vhanged since the 80s. My friends are running a new version of the phototron but the old school one is pretty primitive. Definitely a collectors item and will be worth a fortune someday so dont go cutting holes in it.
That closet is a fire hazard. Don't grow in there with all the clothes. You need to do some rearranging.
A phototron WOULD, with some adapting, make a very nice base for a plexiglass reptile tank- the critters would stay warm and the PT itself looks like an aquarium base anyway, and noises and cords are expected.
