Dehumidifiers and Humidifiers

Humidity swings can make or break your grow cycle. Too dry and plants dried out—too damp and risks of mold, bud rot, or slow growth skyrocket. Our curated collection of humidifiers and dehumidifiers includes compact units perfect for seedlings and tents and powerful, commercial-grade dehumidifiers that remove hundreds of pints per day to control RH in mature grow spaces. 

Explore models with smart controls, built-in humidistat, continuous drainage options. Check out compatible Dehumidifier filters and odor control products and ventilation and ducting to suit your workflow. From portable mini units to overhead LGR systems, easily automate humidity management, so you can lock in ideal Relative Humidity and focus on yield, not mold.

Need help picking the right dehumidifier? Discover the difference between Quest and Anden, two industry-trusted dehumidifiers.

Frequently Asked Questions

What’s the difference between a humidifier and a dehumidifier?

A humidifier adds moisture to the air by releasing water vapor or steam, raising the relative humidity. This is useful when indoor air is too dry, typically below 30–40%, to relieve issues like dry skin and respiratory irritation and to support plant transpiration. A dehumidifier, on the other hand, extracts excess moisture by condensing water from the air or using desiccants, lowering humidity to prevent mold, mildew, musty odors, and protect fragile indoor environments—especially when RH is over 50–60%

What is the ideal humidity range for indoor growers?

Most indoor growers target a humidity range of 40–60% RH, which is generally optimal for plant growth. Early vegetative stages benefit from higher humidity (around 60–70%) to encourage transpiration and vigorous growth, while flowering and bud development stages typically require lower humidity (40–50%) to minimize mold and bud rot risks.

Can I run both a humidifier and dehumidifier at the same time?

Yes, using both devices together can work—but you’ll need precise humidity control. Setting the humidifier to activate below about 50% RH and the dehumidifier to kick in above about 60% ensures they don’t counteract each other. This "dead zone" approach stabilizes humidity without devices running continuously.

How often should I clean and maintain these devices?

A well-maintained humidifier should be cleaned weekly—with distilled water—to reduce mineral deposits and bacterial growth, while dehumidifiers require periodic tank emptying, filter cleaning, and coil maintenance to prevent microbial buildup and maintain efficiency.
