Best Humidifiers For Greenhouse 2023

December 17, 2022 by Editorial Team

The intensity of sunlight in a greenhouse can be hard on plants, causing leaves to burn, wilt, and turn brown. The heat also causes the air to dry out quickly, which can damage plants and cause dry, cracked soil. To combat these issues, greenhouse owners often rely on humidifiers to help keep the air moist and prevent dry, cracked soil from forming. While some greenhouses have humidifiers installed when they’re built, other greenhouse owners have to install humidifiers after the greenhouse is built.

To help you find the best humidifiers for your greenhouse, we’ve researched and vetted dozens of different options so you can trust that these are top-notch.

Read on to learn more about our favorite humidifiers for greenhouse plants.

Best Humidifiers For Greenhouse Buying Guide

Before choosing the best humidifier you should consider following options:

1. Water source: The humidifier you choose should be compatible with your HVAC system, water supply and electricity source.

If you have a forced-air HVAC system, you can use a steam humidifier, which uses hot water to produce steam and delivers it to the ductwork. A warm-air humidifier produces warm, moist air that’s distributed through the ductwork.

A water-source humidifier can use either hot-water or cold-water supply. Depending on the type of supply, you’ll need to purchase a humidifier with the proper connection.

2. Space size: The square footage of the space will help you determine the required humidity output. A general rule of thumb is that a 1,000 square foot space will require a 30-50 gallon per hour capacity.

3. Humidity set point: A setting of between 30-50 percent relative humidity is recommended.

4. Maintenance requirements: Some humidifiers require minimal maintenance, while others have complex parts that need regular replacement.

5. Cost of operation: The energy efficiency of some humidifiers allows them to operate on a smaller electrical bill, while others may require regular replacement of parts and therefore cost more to operate.

6. Cost of replacement parts: Some humidifiers require regular replacement of parts, while others have a simpler system with fewer components.

7. Indication of proper operation: The humidifier you choose should have a built-in indicator that alerts you when the water or filter needs to be replaced.

8. Durability: Some humidifiers are more durable than others. If you plan to use the humidifier for long periods of time, you may want to consider a model with a self-calibrating system that reduces wear and tear.

9. Maintenance costs: Some humidifiers may require more maintenance than others. For example, warm-air humidifiers use a lot of electricity to operate and require regular filter changes. On the other hand, a water-source humidifier requires minimal electricity to operate and uses minimal water.

10. Warranty: Not all humidifiers come with a warranty, so you need to confirm this before making a purchase.

11. Portability: If you plan to use the humidifier for short periods of time, you may want to consider a smaller, portable model.

12. Design: The humidifier you choose should match the decor of the space.

13. Ease of operation: The humidifier should be easy to use and maintain.

14. Noise level: A quiet humidifier is a must if you plan to use it in a bedroom or other enclosed space.

15. Filter: Certain humidifiers have a permanent filter that reduces pollutants, while others have a disposable filter. The type of filter you choose will depend on your preference.

16. Price: The overall price of the humidifier you choose should match your budget.

17. Maintenance: Some humidifiers require more maintenance than others. For example, warm-air humidifiers use a lot of electricity to operate and require regular filter changes. On the other hand, a water-source humidifier requires minimal electricity to operate and uses minimal water.

18. Indoor/outdoor use: Depending on your application, you may want to purchase a humidifier that can be used both indoors and outdoors.

19. Warranty: Not all humidifiers come with a warranty, so you need to confirm this before making a purchase.

20. Maintenance: Some humidifiers require more
