The 4′ x 2′ size grow tent is ideal for the home grower wanting to keep a low profile without having to build a room from scratch. This size fits perfectly in most standard closets giving you the option for a stealthy hydroponic grow. It can house 2-4 plants full cycle, or 6-8 smaller plants during the vegetative stage.
