48" x 48" x 80" model. The light generated by HID and compact fluorescent lighting systems is great for plants, but it can be a source of frustration for gardeners whose living areas are cramped or don’t have an extra room for an indoor garden. With a DarkRoom, however, those frustrations are a thing of the past. A DarkRoom is the foundation of a completely self-contained indoor garden, featuring a lightweight, durable, washable interior reflective lining that keeps more light going where it’s supposed to go: to the plants. The frame supports up to 65 pounds of lighting, ventilation or other equipment, and every unit has access ports that accommodate ducting or other equipment. DarkRooms can be assembled without tools in minutes by one person, and collapse just as quickly for storage. Improved DarkRoom II models also boast enhanced lightproofing measures, more cord access ports, and even stronger corner joints.
