When it comes to indoor grow rooms, nurseries, and greenhouses, healthy humidity levels are of the utmost importance. Too much moisture often leads to mold and mildew growth as well as other plant diseases. The simplest way of automatically and consistently regulating humidity levels is with a dehumidifier.

Plants are constantly absorbing water to attain nutrients so that they can grow to their fullest potential. In addition, humidity levels actually determine how much water your plants absorb. This also means controlling the humidity levels gives you control over each plant's nutrient intake as well.

Ideal grow room dehumidifiers should feature automatic humidity controls, energy-efficient operation, ducting options, and continuous drainage options. These features give you the most control over humidity levels in your grow room or greenhouse and help to streamline the growing process.

During the earliest stages, higher humidity levels are usually required in order to reach optimal plant growth. The exact opposite is true for the rest of the growing cycle when less humidity is often required. It's common practice to have a humidifier for the beginning stages of plant growth followed by a dehumidifier for later stages.

Air circulation and ventilation are also important parts of the process when it comes to indoor growing. Proper air circulation and humidity levels can help prevent mold, mildew, bud rot, and slow plant growth (due to low humidity). Additionally, ventilation fans help regulate temperature and evenly disperse CO2, which naturally settles at the bottom of rooms.

Monitoring humidity levels in grow rooms and greenhouses is crucial. If your dehumidifier doesn't come with a built-in hygrometer or humidistat, consider purchasing an external one to help better maintain accurate humidity levels. Some dehumidifiers and humidistats come with remotes for even easier control and programming.

For those who live out west or in dryer climates, you might need to consider raising humidity levels instead of lowering them for optimal indoor plant growth. The most efficient method of raising humidity levels is the use of a humidifier. Humidifiers replenish moisture levels to help plants thrive and grow. A large humidifier with a significant tank capacity is necessary when humidifying entire grow rooms, greenhouses, or nurseries.

Here at National Allergy, we know indoor growing is not a one size fits all operation. A grow room, greenhouse, or indoor nursery can be as big or small as you may need or want. Either way, no matter how big you're grow is, we hope these tools, tips, and tricks help bring you that much closer to achieving your indoor growing dreams!
