How to Choose the Right Size

Sizing your dehumidifier is critical. Too small, and RH will climb during peak transpiration. Too large, and you’ll waste energy.

General guideline:

A flowering plant can release up to ½ gallon of water per day. As irrigation increases, moisture removal becomes even more important.

If you're unsure, our team can size your rooms for free.

Quick rules of thumb:

  • Choose a model that covers your peak humidity load, not average load
  • Add a 20–30% buffer for irrigation spikes, CO₂ use, and late-flower cycles
  • Larger commercial spaces often run multiple units for redundancy and airflow balance

Key Features That Support Better Crops

Built for CEA Environments

Galvanized steel housing, coated coils, and reinforced components stand up to long-term exposure to moisture, fertilizers, and heavy-duty cleaning.

High Moisture Removal Efficiency

Designed to remove large volumes of moisture with optimized energy consumption — especially important in canopy-dense flower rooms.

Flexible Install Layouts

Ceiling-mount, wall-mount, or floor placement gives growers freedom to design around benches, vertical racks, ducting, and lighting.

Low Noise Levels

Quiet operation minimizes disruption in controlled environments and keeps staff areas comfortable.

Easy Maintenance

Front-panel access makes filter changes and internal cleaning quick and straightforward.

Where Leizig Works Best

Flower Rooms with heavy irrigation cycles

Commercial Facilities running multiple rooms

Why Humidity Control Matters in CEA

Keeping humidity in the right range is one of the most important factors for plant health, crop quality, and predictable yields. When humidity spikes, you risk mold, mildew, and inconsistent VPD. When it drops too low, plants close their stomata, slow growth, and experience avoidable stress.

A reliable dehumidifier is the backbone of a stable grow environment — and Leizig is designed specifically for the challenges of real production rooms.

At A Glance:

Protect your crop during veg and flower

Maintain optimal VPD ranges

Reduce disease pressure

Improve consistency across canopy layers

Maintain environmental control regardless of plant density or irrigation strategy

Customer Feedback
