Cooling Greenhouse Climates for Optimal Growth
Managing greenhouse conditions in Fresno, California, is no easy feat, especially when summer temperatures frequently exceed 100°F. Since the 1980s, Takao Nursery has relied on advanced humidification and cooling technology to maintain the perfect growing environment for their plants. Their partnership with MeeFog Systems has enabled them to optimize greenhouse humidity and temperature while enhancing plant propagation efficiency.
With expansive greenhouse facilities and increasing market demand, Takao Nursery faced the challenge of maintaining consistent humidity and cooling levels. A stable growing environment is essential—not only for plant propagation success but also for disease prevention and overall plant health. In Fresno’s arid climate, finding the right balance became a critical factor in ensuring sustainable operations.
Key Challenges in Greenhouse Cooling:
To achieve optimal plant growth, Takao Nursery had to address several critical challenges:
- Controlling greenhouse humidity and temperature fluctuations
- Preventing moisture-related diseases such as botrytis
- Ensuring consistent plant hydration without oversaturation

MeeFog Humidification & Cooling System
To address these climate control issues, Takao Nursery implemented a MeeFog high-pressure fog system, designed to:
- Deliver ultra-fine mist for uniform cooling and humidity
- Reduce plant stress by maintaining stable growing conditions
- Improve cutting propagation success rates
- Enhance overall greenhouse energy efficiency
Unlike conventional misting systems, MeeFog’s technology offers a significant advantage. The system ensures the mist evaporates rapidly, cooling the air while maintaining optimal humidity levels without excessive water usage. This results in faster plant growth, lower disease risks, and improved plant quality.
Technological Upgrades: Advancing Greenhouse Efficiency
2004 Upgrade: Expanding Capacity
In 2004, owner Danny Takao installed a 5hp 3-phase motor and a 1050 model pump, significantly boosting the nursery’s operational capacity. This upgrade enabled them to keep up with increasing plant orders while maintaining an ideal growing environment.
Recent Innovation – Mobile-Mee Greenery Sprayer
More recently, Takao Nursery added the Mobile-Mee Greenery Sprayer, a game-changer in greenhouse climate control. This advanced sprayer delivers a super-fine mist, hydrating plant cuttings without over-wetting the foliage or soil.
Danny Takao on the Mobile-Mee System:
"Cuttings were surrounded by a SUPER fine mist WITHOUT over-saturating the foliage and WITHOUT impacting the wetness of the soil in the slightest! It’s exactly what you want to achieve when battling botrytis. Score: 10 out of 10.”

Scalability and Long-Term Benefits
Today, Takao Nursery has significantly expanded its greenhouse space and continues to rely on MeeFog technology for precision humidity control and energy efficiency.
🌿120,000 square feet of Agra Tech greenhouses
🌿 40,000 square feet of cold frames
The original MeeFog system was first installed in the 1980s to humidify 25,000 square feet of greenhouse space using 240 precision fog nozzles. This energy-efficient system enables rapid evaporation cooling, ensuring plants receive the ideal environment for healthy, consistent growth.
Sustainability and the Future of Plant Care
For over three decades, Takao Nursery has demonstrated innovation, efficiency, and sustainability in greenhouse climate control. By embracing MeeFog humidification systems, they have optimized propagation success rates, reduced energy consumption, and positioned themselves as industry leaders in controlled-environment agriculture.
MeeFog’s Role in Sustainable Plant Care
As demand shifts toward drought-tolerant plants, precise humidity control becomes even more critical. MeeFog’s advanced technology enables Takao Nursery to make this transition smoothly while maintaining consistently high plant quality.
Danny Takao on System Reliability:
"We’ve looked at other systems but always stayed with MeeFog. We are starting to do more drought-tolerant plants, so precise humidity adjustments are crucial for better plant acclimatization. It would be impossible to achieve this with a conventional misting system.”
