Dry run on my grow room is too dry

  1. So I just recently finished my grow cabinet to house a single plant, and I'm having some environmental problems.
    Being a former fish enthusiast and listening to Jorge Cervantes, I know it's best to plan before you plant. As such, I'm doing a week long dry run to be sure that I can maintain a stable environment before introducing a plant.
    The main problem I'm currently having is with humidity. I live in a desert climate, and the humidity in the cabinet hovers between 30-35% and 78-81º. I know that the humidity is much too low to start seedlings, and clones later on. I've tried putting a steaming kettle in there, setting a bowl of water, and nothing seems to work. I'm about to try getting a small cool humidifier to add moisture in short bursts being that it's a small enclosure (71"H x 24"W x 16"D).
    My buddy suggests that having moist soil in there along with a transpiring plant should add 30% to the humidity, but I'm fearing that it won't be enough. Any suggestions?

  2. I doubt it raises 30%,
    Low humidity= humidifier

    We have low humidity here in the winter, I use one
  3. I have low humidity all the time because I live in the desert.

    A humidifier will work just fine.
  4. <sup>I have soaked a few sweat shirts or other garments and hung in the room. </sup>

    A growing plant will probably adapt to the low humidity fairly well, but when you have seedlings or clones then high humidity is vital.  They do not have the ability to absorb enough water quickly enough to stop them from drying out.
    Rather than trying to control the humidity of your whole grow room, if you cover the seedlings with something instead you can make the environment humid just for your seedlings.  You could give them their own personal humidity tent with some cut up plastic bottles, or transparent plastic bags work as long as they don't collapse and touch the leaves.  As long as it lets the light in, keeps most of the humidity in, but isn't sealed all the time because air circulation is still important.
    Then when they have established themselves with a good root system, they will be better able to survive the low humidity when you remove the shelter.
  6. Get a humidifier you're gonna want it for drying anyways..humidity is under 10% here in winter and i leave it running while drying to keep it at 50..growing plants dont mind it they will just grow smaller leaves to slow transpiration
