Controlled environment agriculture courses offered online
UC Davis Continuing and Professional Education and The VINE launch indoor farming classes
A new, comprehensive and advanced learning experience in indoor farming is now available for growers. The VINE, an initiative of University of California Agriculture and Natural Resources (UC ANR), and UC Davis Continuing and Professional Education have opened enrollment for their new Controlled Environment Agriculture Program. Courses begin on July 1.
Controlled environment agriculture is a technology-based method of growing plants that offers precise control over temperature, humidity, light, carbon dioxide and air circulation. CEA can take place in greenhouses, indoor vertical farms or hydroponic farms.
"Unpredictable and extreme weather, pests and growing demand for year-round, local produce are driving growers to move crop production indoors,” said Gabe Youtsey, UC ANR chief innovation officer and co-founder of the VINE.
The CEA Program is designed to impart a deep understanding of both the scientific and practical aspects of indoor farming. The series of four detailed courses, designed to be completed in less than a year, are offered through a flexible online platform. This program is suitable for a wide range of professionals from various sectors including farming operations managers, horticulturists, indoor farming specialists, early-career agriculture professionals, and those in related fields.
"As the agricultural sector evolves, our CEA Program aims to provide the foundational knowledge and practical skills crucial for success in controlled environment agriculture," said Youtsey. "We are preparing participants to effectively manage and innovate within their own agricultural practices."
Participants in the program will receive instruction from international experts in controlled environment agriculture. The curriculum includes an exploration of various business models in CEA, optimal crop selection for different environments, and effective strategies for managing pests and diseases. Additionally, it covers the application of data to enhance growing conditions and profitability, as well as best practices for ensuring product safety and quality.
"Students in this program will gain a deeper understanding of the operational aspects of indoor farming and how they can apply this knowledge to real-world scenarios," said Jennifer Greenier, Ph.D., UC Davis Life Sciences Workforce Development director. "We are committed to providing educational pathways that nurture the skills necessary for advancing career opportunities in agriculture."
The Controlled Environment Agriculture Program is structured around four core courses, each designed to build specific skills and knowledge essential for success in indoor farming:
- Introduction to CEA – Fundamentals of indoor farming, business models, and technological advancements.
- Plant Production in Indoor Farming – Planning and implementing effective operations, understanding plant physiology, and nutrition management.
- Postharvest Processes: Ensuring Crop Quality and Safety in CEA – Food safety, proper storage, distribution, and marketing strategies.
- Data-driven Growing – Developing data management skills and optimizing operations through data analytics.
Individual course fees are $1,000 to $2,000 and the full CEA Program is priced at $6,000. Completely online, the courses are accessible to professionals both domestic and international.

Green Hall of Famer Oki retires after 29-year UC career
UCCE specialist's research prevents water pollution, reduces water use
When interviewed to become a University of California Cooperative Extension specialist in environmental horticulture, Lorence “Loren” Oki was asked what kind of research he wanted to conduct.
In response, he showed the hiring committee a photo of a residential gutter. “Water is a big concern, and I found very little research on runoff from homes,” said Oki, explaining that studying residential runoff is what “started his career” with UC Agriculture and Natural Resources back in 2002.
Although he remains active supporting growers and advising industry leaders, Oki retired from UC ANR in July 2023. Before joining ANR, Oki worked as a researcher for UC Davis' Department of Environmental Horticulture studying greenhouse irrigation in 1994, bringing his total time with the University of California to 29 years.
Oki, professor emeritus of Cooperative Extension at UC Davis, led many research projects that advanced the green industry which includes landscapes, nurseries and floriculture.
“Loren is the epitome of a specialist,” said Darren Haver, UC ANR's Research and Extension Center system director, who has worked with Oki for more than 20 years on projects that have significantly improved urban water quality and water conservation efforts across California.
Research influences pesticide management statewide
With a $3 million grant funding a statewide study, Oki and Haver set out to characterize runoff from residential sources over a five-year period. They determined the volume of irrigation runoff from residential land use, as well as the pollutants in the runoff.
Oki and Haver, co-principal investigators, along with researchers from UC Davis and UC Riverside, discovered that the degradation products of the insecticide fipronil – commonly found in runoff water – were more toxic than its parent compound. The study led to an investigation of human pathogens and pathogen indicators in residential runoff, the first of its kind.
Another contribution was the early detection of a new pesticide used for ant control, enabling strategies to be put in place to prevent it from reaching local streams and creeks. Oki and Haver's work also persuaded the California Department of Pesticide Regulation to change pesticide labels to minimize the chances of pesticides moving off target during irrigation and rain events.
These changes included preventing pesticide application before predicted rain and preventing irrigation after applications, keeping pesticides from impervious surfaces, and restricting applications on lawns and landscape beds within two feet of impervious surfaces and others.
Plant trials expand beyond California
Oki was also the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials, the California component of that project. The UCPLIT trials originated in 2004 at UC Davis as a research project by Karrie Reid, retired UCCE environmental horticulture advisor for San Joaquin County, while she was pursuing her master's degree. In 2017, the irrigation trials were duplicated at the South Coast Research and Extension Center.
These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water. Throughout the trial, Oki identified many landscape plants, including rose cultivars, that remain aesthetically pleasing with little water.
Today, the trials have expanded beyond California as the Climate-Ready Landscape Plants Project at Oregon State University, University of Washington, University of Arizona and Utah State University.
Growing up in the nursery industry
In 2017, Oki obtained tenure, allowing him to expand his professional responsibilities to include production horticulture, specifically greenhouses and nurseries, an industry he was extremely familiar with. “I come from a nursery family,” Oki explained. “My grandfather started Oki Nursery in the early 1900s.”
During World War II, Oki's family was incarcerated in the Poston Relocation Center in Arizona and lost their homes and property. When they were released, they returned to the nursery industry to rebuild their lives. “After World War II, my father and uncle got more involved with my grandfather's work,” he said.
The Oki family played an instrumental role in technological development for nurseries in general. Oki Nursery, which was located in Sacramento, worked closely with IBM and was the first to use a computerized system in the industry.
Oki developed computerized scheduling for the bedding plants, poinsettias, chrysanthemums, bulbs and other crops. He developed a method to calculate the cost of any crop grown by the nursery at any point in the crop cycle and computerized greenhouse environmental and irrigation controls. This may not sound impressive now, but that was in the 1980s.
“My father was known for being progressive and he also knew everyone at UC Davis,” said Oki. “He wanted to work with anyone who had an interest in doing something good for nurseries.”
Inducted into Green Industry Hall of Fame
In the 1950s, Oki Nursery partnered with researchers from UC Davis' agricultural engineering program and developed the overhead sprinklers commonly used in nurseries today. Until the 1980s, Oki Nursery was the largest nursery in Northern California. Before it shut down in 1993, Oki worked in the family business as a greenhouse manager when runoff became a growing concern.
“I remember getting served with a notice by the Regional Water Quality Control Board stating that we needed to prevent runoff because it was polluted with nitrate fertilizer, which was common in the nursery industry,” Oki said.
One of those efforts focused on using controlled-release fertilizer instead of applying fertilizer via irrigation as a liquid feed. “What we learned is that if we converted nurseries to controlled-release fertilizer, we could reduce the nitrate runoff,” he said. While a member of the Oki Lab, Bruno Pitton earned his Ph.D. studying nursery hydrology and the fate of nitrogen fertilizers in container crop production adding to the information on runoff and nitrate management. Pitton is now the environmental horticulture advisor for Placer and Nevada counties.
In 2023, Oki was inducted into the Green Industry Hall of Fame, which recognizes individuals with a minimum of 20 years in the landscape, nursery or floriculture industry and who have made significant contributions to the field.
Having grown up in the industry, Oki said that his father taught him to never be afraid to try new things. “If you think you have an idea that might work, do the best you can to make it work. If it doesn't work out, then it doesn't work out. And that's OK,” he said.
Revitalizing space for greater impact
This mentality encouraged Oki whenever tackling new tasks, like rebranding the California Ornamental Research Federation, a space for education and collaboration, as UC Nursery and Floriculture Alliance.
In 2009, Oki and David Fujino, executive director of the California Center for Urban Horticulture, became co-directors of CORF, which catered to the cut flower industry. At that time, Oki and Fujino realized that nurseries generated much greater revenue in the state than cut flowers.
“It was a strategic decision to change CORF to UCNFA, which included floriculture and nurseries in the name,” Fujino said. Combined, nurseries and floriculture have consistently placed in the top five agricultural commodities in the state.
When reflecting on their partnership, Fujino said that working with Oki was a “natural fit.” “I couldn't have asked for a better partner, a better colleague and, ultimately, a better friend to have my back and work side by side,” he added.
Since UCNFA's launch, the two have worked to maintain the group's impact by hosting “Ask your Advisor” webinars to connect advisors to growers, as well as co-hosting large-scale events such as the annual conference for the International Plant Propagators' Society — an organization focused on greenhouse and nursery production education — for the Western Region, which Oki's father helped establish in the 1960s.
Encouraging a return to education
Gerry Spinelli, UC Cooperative Extension production horticulture advisor for San Diego County and member of UCNFA's administrative committee, described those who have learned from Oki as his sons and daughters. “When I meet someone that's learned from Loren or worked with him, that person instantly becomes my friend. That's the kind of effect Loren has on us,” Spinelli said.
Grant Johnson, UC Cooperative Extension urban agricultural technology advisor for Los Angeles and Orange counties, credits Oki for his master's degree in horticulture from UC Davis.
“Loren gave me a lot of direction as far as career choices and research interests. He instilled in me a dedication to life-long learning, just like he continues to do,” said Johnson. Before Oki became his professor, Johnson worked with Oki as a staff research associate at the South Coast Research and Extension Center in Irvine.
Another influential person in Oki's life is John Kabashima, emeritus environmental horticulture advisor for UCCE Orange and Los Angeles counties and fellow Green Hall of Fame inductee. Like Oki, Kabashima grew up in the nursery industry.
Oki, who earned a bachelor's degree in ornamental horticulture from Cal Poly San Luis Obispo and a master's degree in plant science from UC Riverside, decided to pursue a Ph.D. in ecology at UC Davis with Kabashima's encouragement.
While Oki was still working in his family's business, Kabashima said that Oki relied on UC ANR researchers for scientific information and felt like Oki wanted to be one of them. “I told him that he's a good nursery guy, but he's a better scientist,” said Kabashima. “His heart is in science.”
The two began working together as soon as Oki became a graduate student and have been colleagues and friends for nearly 40 years. “My favorite response from Loren whenever people ask him a question is, ‘It depends,'” Kabashima said. “It always leads to people opening up and giving more context. That's what Loren does, he gets you to think.”
/span>/h3>Public invited to observe prescribed fire training in Santa Cruz County
First Forester TREX to be held June 3-6
California's first-ever Forester Prescribed Fire Training Exchange event focused on bringing together professional foresters, forest managers and fire practitioners will occur June 3-6 near Watsonville. The four-day event is being hosted by the Central Coast Prescribed Burn Association, which empowers the public to build a culture of good fire and supports private landowners in conducting prescribed burns in Monterey, San Benito and Santa Cruz counties.
There will be one burn conducted during the event, likely on June 4 or 5, which will be open for the public to observe.
Prescribed Fire Training Exchanges (TREXs) first came to Northern California in 2013, and have made a positive cultural shift concerning prescribed fire, within both regional fire services and the general public. These “good fire” TREX events have drawn significant attention, especially in the context of more severe wildfire seasons.
After months of cross-organizational planning, the four-day long training will be focused on exploring the connections between sustainable forest management, wildfire resilience, timber harvesting, prescribed fire, and will include a burn within a commercially harvested redwood forest. The TREX will provide experiential training opportunities to forest managers and planners to advance statewide knowledge of how to conduct prescribed fire in merchantable timber stands.
Along with the prescribed burn, the program will include lectures, local tours, and open discussions on how to incorporate fire into timber management, burn planning and timber harvest planning, pre- and post-fire considerations, and permitting mechanisms for fire and timber harvesting. Presentations will be given by local forestry consultants, University of California Agriculture and Natural Resources, CALFIRE and local fire practitioners.
The burn location will occur near Mount Madonna, on private land with access allowed for accompanied observation only. Be advised, while the ForesterTREX planning team works closely with theMonterey Bay Air Resources District to assure good smoke dispersal, smoke may be seen and be present in these areas during and after a burn. Please see the Central Coast Prescribed Burn Association webpage at calpba.org/centralcoastpba for updates close to the burn date.
Participants and partners include the Mount Madonna Center, members of the Amah Mutsun Tribal Band and the Esselen Tribe of Monterey County, University of California Agriculture and Natural Resources, Resource Conservation District of Monterey County, CALFIRE, local land trusts, scientists, ranchers, students, researchers, land managers and others. The Central Coast Prescribed Burn Association is currently funded via California Coastal Conservancy grants.

UC Master Gardeners empower college students to garden for mental wellness
Although training is required to become a University of California Master Gardener, the benefits of gardening can be experienced by anyone and everyone.
“As long as you're willing to get your hands dirty,” said Laurie Menosky, a UC Master Gardener volunteer in Orange County, “you can learn to grow all sorts of things.”
In early April, Menosky partnered with ETN Medical Infusion (a clinic in Orange County) and the Sustainability Program for Student Housing at UC Irvine to teach students how to grow tomatoes. Menosky welcomed all in attendance, including families with toddlers who seemed fascinated by the 60 tomato plants atop one of the tables in the room.
The UC Master Gardener Program is a part of UC Agriculture and Natural Resources. During her presentation, Menosky taught participants how to choose varieties that fit their taste and growing environment, how to cultivate a thriving environment, and how to control pests and diseases using integrated pest management practices.
“We have 16,000 residents at UCI and sustainability is one of our values. One of the ways we engage students is through on-campus gardens,” said Rachel Harvey, sustainability program manager for UCI Student Housing and a UC Master Gardener volunteer in Orange County.
UC Irvine has one teaching garden reserved for undergraduate learning, and three gardens operated and maintained by graduate students. “I was on the waiting list for a garden plot for a while, but it was totally worth the wait,” said Johanna Rinaman, a fifth-year Ph.D. student studying physical chemistry.
While the highlight of the event for many people was the opportunity to take a tomato plant home, another important takeaway was how gardening can be a good activity for your mental health. Sarah Nghiem, family medicine specialist at ETN Medical Infusion, who worked closely with Menosky, was instrumental in developing the mental health content for the day, encouraging attendees to attempt gardening with a mental health perspective.
Nghiem and her team received funding from the Orange County Health Care Agency through the Mental Health Services Act to work with transitional aged students (15-24 years-old) on understanding the importance of mental health, which led to the collaboration between UC Irvine, her alma mater, and the UC Master Gardeners of Orange County.
“I didn't do any gardening during the winter, and I felt a lot more anxious and depressed during that time,” Rinaman said. “I know gardening improves mental health because I've immediately felt a difference whenever I spend time with plants.”
Rinaman, whose father taught her a lot of what she knows about gardening, said that having access to a 4 feet by 6 feet plot to grow her own food is one of the many things she loves about UC Irvine.
Like Rinaman, Menosky turns to gardening to decompress, especially during the long days of summer. Teaching others about the physical and mental benefits of gardening gives her an opportunity to share her experience and, hopefully, help others find new ways to manage stress.
“We often have attendees come back years later telling us how our information has helped them and how much more they are enjoying their time in their gardens,” she said.
To conclude her presentation, Menosky instructed participants to line up for their own tomato plant. Attendees took their plants outside to transfer them from a small pot to a grow bag – a type of container that helps root structure development.
Cassie Ekwego, a third-year transfer student studying civil engineering, couldn't hide her excitement after carefully lifting her plant. “I don't think I realized how attentive you need to be when working with plants,” said Ekwego, reflecting on what she learned from Menosky's presentation.
Now that she has her own plant to care for in her own home, Ekwego is eager to put her new knowledge to the test. “I love tomatoes, but this is going to be a huge responsibility for me,” she said.
Randy Musser, UC Master Gardener program coordinator for Orange County, said that while he enjoys talking to avid gardeners, bringing gardening to new people in the community is special to him. “This tomato workshop is particularly exciting for me because it is an opportunity for the UC Master Gardeners to grow our connection to UCI and young people just starting off on their gardening journey,” said Musser.
With a generous contribution from UC Master Gardener volunteer Sheila Peterson, Musser was able to purchase enough supplies to help attendees, like Ekwego, jumpstart their gardening experience.
Students, whose stress levels can skyrocket throughout the school year, value opportunities to be outdoors, try something new and be in community. “The garden is a different type of classroom. It's a place where students can learn and experiment, hopefully in a way that reduces stress,” said Harvey of UCI Student Housing.
Ekwego, who tried gardening for the first time while volunteering at UC Irvine's teaching garden, is just one of the many students inspired by their experiences. “Gardening reminds me that it's OK to get my hands dirty,” Ekwego said.
