Greenhouse cabinets are a way to bring plants requiring different biomes into your home, office, work, business or nearly any building. They are exactly as they sound. A greenhouse in cabinet form. They can range anywhere from a small wall cabinet to a large standing cabinet. They can be placed in front of a window or in a dark room with grow lights implemented. Humidity can also be controlled through humidifiers, pebble trays, plant groupings, or dehumidifiers to create the optimal environment for the plants. I have started a small collection of plants that I tend to and even though I have optimized the shelving unit as much as I can without significant investment the humidity and pest control is wildly variable.
