i imagine you could use it, a mother plant would be excelent in there. (i think cause i never have used a phototron) for flowering though you wouldnt want the panels to allow light in. i think i really would use it as a novelty for other types of plants. reading my first high times in the 80's this sure brings back some memories/wishes of growing. the natural resource class was donated about a dozen of those things at that time by the police after a bust. as you can imagine all the students fingers were itching to do a project with them, but it never happened while i was there. lol, a bunch of teenagers drooling over a stack of phototrons, priceless.
