A grow room is a room set up to allow a controlled environment for growing plants. You can use artificial lights, hydroponics and vaporisers to control everything from the temperature to the humidly in a bug-free environment. This is an excellent way to grow vegetables such as tomatoes in an indoor garden. With enclosed, warm spaces, however, humidity has little place to go. This can over-saturate your plants and cause rotting and decay.

Instructions

  1. 1

    Position a freestanding dehumidifier in the centre of the grow room on the floor. Purchase the largest dehumidifier you can for your room. Although the room is likely relatively small and the charts listed on the box will indicate a smaller dehumidifier will work, you must take into account that the humidity levels in the room are drastically higher than a standard room of the same size because you are using the room to grow vegetables.

  2. 2

    Secure a garden hose to the drain valve located on the back of the dehumidifier. Since you will remove large amounts of water from the air, you do not want to use the collection pan because you will need to change it several times throughout the day.

  3. 3

    Route the other end of the hose to an outside location where the water can freely drain.

  4. 4

    Mount a hygrometer onto the wall. A hygrometer measures relative humidity.

  5. 5

    Turn on the dehumidifier and run it until the hygrometer indicates acceptable levels. The level of humidity will differ depending on the type of vegetables you are growing.
