Quest 706 Overhead Dehumidifier: Maximum Efficiency for Serious Grow Rooms!

When it comes to optimizing your grow room environment, humidity control is non-negotiable. Quest dehumidifiers have set the gold standard in the industry, and the Quest 706 Overhead Dehumidifier is their flagship model, built to handle large-scale indoor gardening with precision, power, and exceptional energy efficiency. Whether you're cultivating a commercial operation or a dedicated grow room at home, this dehumidifier offers the ultimate solution to humidity control.


Why Choose the Quest 706 Overhead Dehumidifier?

The Quest 706 is more than just a dehumidifier—it's an investment in your plants' health and your grow room's performance. Designed with proprietary coil technology that you won’t find anywhere else, this powerful unit is engineered to maximize water extraction, reduce energy consumption, and provide the most efficient, reliable humidity control possible. It’s a game-changer for serious growers who want nothing less than the best.


High Humidity vs Low Humidity

High humidity effects nutrient uptake and distribution as the plant structures rely on a difference in humidity between the pores (stomata) and air, in high humidity situations, the plant may stop transpiration which reduces mobility of nutrients, slowing growth.


Low humidity can force plants to transpire too quickly which may lead to leaf wilt if the plant is unable to replace these liquids faster than they are removed.


Plants are best facilitated with different levels of humidity throughout their lifespan; Overall, cuttings and young seedlings need high humidity (between 70 - 80%) before they root as they’ve got a limited capacity for up-taking water without roots. Plants in the vegetative stage require between 50 - 70% RH, while flowering and fruiting plants demand lower humidity levels (between 40 - 60%).


The quest dehumidifier has a tank adapter so you can drain the water this unit absorbs back into your reservoir for use in your irrigation systems.


Key Features of the Quest 706 Dehumidifier:

  • High Capacity Performance: Removes up to 706 pints (335 liters) of water per day at 26.7°F and 60% relative humidity. Perfect for large-scale operations
  • Energy Efficiency: With a rating of 3.4 liters per kWh, this dehumidifier provides maximum moisture removal with minimal power consumption
  • Patented Coil Technology: Quest’s unique coil design ensures optimal moisture extraction, setting this unit apart from other models on the market
  • Ductable Intake and Exhaust: Available kits allow you to integrate the dehumidifier seamlessly into your setup, giving you full flexibility in your grow room
  • Direct-Wired for Reliability: Requires direct wiring for stable and secure power supply
  • 3-Year Warranty: Peace of mind with a robust warranty for years of dependable operation
  • Low Voltage Terminal Block: Offers external control options, giving you more ways to fine-tune your system
  • Heavy Duty & Durable: Weighing in at 350 lbs (159 kgs), this robust unit is built to last even in the most demanding grow environments

What Makes the Quest 706 Stand Out?

The Quest 706 is designed specifically to meet the needs of serious growers. It’s not just about removing moisture; it’s about doing so with incredible energy efficiency and reliability. Here’s why the Quest 706 is the ideal choice for your grow room:

  • 1. Precision Water Removal: Humidity control is essential for maintaining healthy plants, and the Quest 706 leads the way with its high water removal capacity. If your grow room consumes up to 50 liters of water per day, this dehumidifier can handle it—no problem. For every 1000W of light in your setup, you’ll need about 10L of dehumidification per day to keep the room’s humidity in check throughout all growth stages. The Quest 706 meets these demands, ensuring your plants stay in the ideal environment.
  • 2. Unmatched Energy Efficiency: High-capacity dehumidifiers often come with a hefty electricity bill. The Quest 706 bucks that trend with outstanding energy efficiency. With an efficiency rating of 3.4L/kWh, it extracts more moisture per unit of power than any other comparable unit, saving you money while maintaining perfect humidity.
  • 3. Flexibility and Customization: Every grow room is unique, and the Quest 706 provides the flexibility you need. Its ductable intake and exhaust kits make it easy to integrate into your existing setup, while external controls give you full command over operation. Whether you need it to work in a tight corner or fit seamlessly into a larger HVAC system, the Quest 706 is up for the task.

Maximizing Plant Health & Yield!

Humidity control isn’t just about comfort for your plants—it’s about optimal growth. High humidity can cause mold, mildew, and pest problems, while too little moisture can stress your plants. The Quest 706 ensures your grow room maintains the perfect environment, keeping humidity levels steady to promote vigorous growth, improve photosynthesis, and boost yields.

    Prevents Mold and Mildew: By controlling excess moisture, the Quest 706 reduces the risk of fungal growth and harmful pathogens.

  • Supports Healthy Growth: Proper humidity levels enable plants to efficiently transpire and absorb nutrients, resulting in stronger plants with higher resilience.

  • Improves Yields: When humidity is controlled, plants grow faster and healthier, leading to bigger, more robust harvests.


Built for Durability and Peace of Mind!

A Quest 706 is not just powerful—it’s built to last. With a durable, heavy-duty design and a 3-year warranty, you can trust that this dehumidifier will keep working season after season, providing uninterrupted service and peace of mind.


Your Next Step to Grow Room Excellence!

Ready to take your grow room to the next level? The Quest 706 Overhead Dehumidifier is the ultimate tool for controlling humidity, improving plant health, and boosting your yield. With its powerful performance, energy efficiency, and durable design, it’s the perfect choice for professional growers who demand the best.
