Maintaining Grow Room Yields During Drought: Part III
October 27, 2015
In the third installment of our drought series, we explore how to harvest dehumidifier condensate for your grow room. By following simple maintenance best practices, like consistent filter cleaning and testing, you can tap into a sustainable and free water source while ensuring your plants thrive even when external water supplies are limited.


Maintaining Grow Room Yields During Drought: Part II
October 9, 2015
Discover how your grow room dehumidifier can become a sustainable water source during drought conditions. By reclaiming condensate, growers can generate clean, renewable water that often surpasses reverse osmosis quality. Learn how these systems work, why the water is safe for your plants, and how to maximize your yields while conserving precious resources.


Maintaining Grow Room Yields During Drought: Part I
October 1, 2015
Drought conditions and water restrictions are impacting grow room profitability across the country. However, limited water supply does not have to mean lower yields. In this post, we explore how managing grow room lights, CO2 supplementation, and dehumidification can help you reduce overall water consumption while maintaining high-quality crop production despite scarce water resources.


Dude Grows Podcast with Quest
July 28, 2015
Are you using residential dehumidifiers in your grow room? QUEST product manager Clif Tomasini joins the Dude Grows Show to explain why specialized equipment is essential for plant health. Learn about the importance of dehumidifier durability, proper sizing for transpiration rates, and why redundancy is the secret to protecting your crop from pests and mildew.


Carbon Dioxide and Better Indoor Harvests: Part 3
July 7, 2015
In our final installment on indoor CO2 supplementation, we examine why plants need oxygen, not carbon dioxide, during their nighttime respiration cycle. Learn why interrupting darkness stunts growth, why energy digestion is vital for flowering, and how to use dehumidifiers to maintain the perfect grow room environment for your most successful harvest yet.


Carbon Dioxide and Better Indoor Harvests – Part 2
June 29, 2015
Carbon dioxide serves as a vital nutrient that drives photosynthesis and significantly boosts indoor crop yields. By maintaining optimal CO2 levels during daylight hours, growers can accelerate plant development and increase production by up to 40 percent. Learn how to properly manage CO2 enrichment and balance environmental factors to ensure your plants thrive throughout their growth cycle.


Carbon Dioxide and Better Indoor Harvests – Part 1
June 16, 2015
While often viewed negatively in the news, carbon dioxide is actually the fundamental building block for healthy indoor plants. By understanding how photosynthesis works and the role CO2 plays in creating plant mass, you can optimize your grow room environment. Join us as we explore the essential science behind maximizing your harvests with carbon dioxide.


Control Humidity to Best Fight Powdery Mildew
May 15, 2015
Powdery mildew thrives in high moisture environments, posing a major threat to crops. Instead of relying on pesticides, focus on environmental control. By maintaining relative humidity at 50 percent or lower, you can prevent mold at the source. Properly sizing a commercial-grade dehumidifier to match your plant transpiration rates is the most effective defense.


Let There Be Light – the Right Light
May 13, 2015
Achieving healthy plants and maximum yields requires mastering your grow room lighting. While HID and CFL lamps were once the standard for indoor gardening, LED technology has become the superior choice. LEDs offer improved energy efficiency, lower heat output, and full-spectrum coverage, eliminating the complex light swapping formerly needed for different plant growth stages.


Optimal plant growth depends heavily on maintaining the correct temperature throughout every life stage. From seedlings to flowering, getting the balance right optimizes photosynthesis and metabolism. Learn how to adjust temperatures based on light cycles, carbon dioxide supplementation, and growth phases to ensure your plants stay healthy and produce the highest possible yields.


For Robust Plant Growth Maintain Proper Humidity Levels
April 23, 2015
Proper humidity levels are essential for healthy plant growth and high yields. When air is too dry, plants may suffer from nutrient burn, while excessive moisture encourages mold and fungal infections. Discover the ideal relative humidity ranges for every stage of your garden, from seedlings to flowering, to ensure your plants thrive throughout their lifecycle.



The Scourge of Powdery Mildew: Prevention Is Best
March 11, 2015
Powdery mildew is a gardener's nightmare that is difficult to eradicate once established. The most effective way to protect your harvest is through proactive prevention. By controlling your grow room humidity, ensuring proper air filtration, and managing your plant spacing, you can maintain a clean environment and stop fungal spores before they begin to spread.


The Scourge of Powdery Mildew: How Do You Treat It Once It’s Occurred?
February 24, 2015
Discover effective ways to combat powdery mildew in your garden once it appears. From natural solutions like hydrogen peroxide and milk to the importance of environmental control, learn how to manage and prevent WPM infections. While some treatments show promise, maintaining proper relative humidity remains the most reliable strategy for protecting your valuable crops.



The Scourge of Powdery Mildew: An Overview
February 11, 2015
Have you noticed mysterious white spots on your plants? This could be powdery mildew, a persistent fungal infection that thrives on leaves and stems. Learn how this condition starts, spreads through airborne spores, and eventually stunts growth. Explore the basics of this common horticultural threat and prepare for our upcoming series on effective treatment and prevention.


Look For Powdery Mildew
October 23, 2014
Powdery mildew thrives in cool, humid environments with poor air circulation. Overcrowding, shading, and improper watering techniques often create the perfect conditions for fungal growth. By controlling nighttime humidity levels and improving airflow, gardeners can prevent these infections. Learn how to manage the environment and protect your plants from this persistent garden disease today.
