FAQs on Best Humidifier for Grow Room

1. Where to Place The Dehumidifier In The Grow Room?

The position of the dehumidifier will depend on the size of the grow room. The first action to take will be to purchase the ideal number of dehumidifiers suitable for your grow room so that there’s enough to go round and all your plants can benefit from it.

When placing your device, its best to place it close to the source of the humidity problem. It’s also ideal to place it in a central area where air can be drawn from all angles and where it has access to all utilities. If there is a grow light in your grow room, its best to place your dehumidifier close to the grow light but ensure its far away from the plants (this is depending on the capacity of the dehumidifier).

2. How to Calculate Dehumidifier Size for Grow Room?

To be able to evaluate the size of the dehumidifier needed to eliminate moisture and odor from your grow room efficiently, you will need to make some few but simple calculations.

All dehumidifiers are rated on pints per day. Hence, a dehumidifier that’s rated 20-pints per is only able to remove 20-pints of water from the grow room every day. While a dehumidifier rated 70-pints per day will remove 70 pints of moisture every day. Therefore, to determine the size of the dehumidifier needed by your grow room, there is a need to know the size in terms of square feet of your grow room.

Calculating Dehumidifier Size for a Grow Room

If for instance your grow room contains 50 plants and you water each plant with one gallon of water per day, then it means you have 50 gallons of water that need to be removed every day.

Thus:

{Number of plants} x {Gallons per day per plant} x 8 {Gallon to pin factor} = {Recommended dehumidifier performance}

Since humidifiers are rated in pints, the gallon needs to be converted to a pint and to do this; you will need to multiply by 8. Using our example above, that gives 400 pints.

Therefore, it means that you will need to purchase a humidifier that’s able to remove 400 pints of water per day, but for the sake of efficiency, go a bit higher by purchasing one of 450 to 500 pints. You don’t need to purchase a single dehumidifier for this purpose but can split the number between multiple devices. If you don’t water your plants daily, you only need to find the average based on the rate you water your plants.

3. How much water should a dehumidifier collect in a day?

While most manufacturers like to lay claims that their humidifiers can collect ten to twenty liters of water every day on small dehumidifiers and up to fifty liters on larger dehumidifiers, the reality is that this can only happen under extreme conditions such as 85% relative humidity at a temperature of 30oC.

Typically, for a 60% relative humidity at 20oC, most dehumidifiers are only able to remove 30% to 40% of their capacity rating. For instance, a 10-liter dehumidifier will only be able to remove about three to four liters of water per day while a 20-liter dehumidifier at a relative humidity of 55% and 60% and the dial set at "continuous" will remove about six to eight liters of moisture.

4. Will a dehumidifier make a room cooler?

With dehumidifiers, hot air gets cycled back into the room as cool air. But while a dehumidifier does not produce cool air, it helps to cool down the temperature of a room. By removing humidity from the air, it leaves the atmosphere much cooler and comfortable.

5. Is it safe to run a dehumidifier constantly all the time?

Only run your dehumidifier when the humidity level is higher than 50%. When your dehumidifier is being run constantly without stop, your appliances over time will probably run continuously as well, this makes the humidifier have little or no impact on the quality of air in your living space or grow room. It is therefore advisable to run your dehumidifier during the daylight hours but put off at night.

Conclusion

Dehumidifiers are necessary for moist or wet grow rooms. They not only remove excess moisture from the environment leaving just the right amount of water needed for proper growth of plants, but they also remove the foul odor that usually associated with grow rooms.
