Plant Empowerment offers the fastest route to sustainable and profitable horticulture worldwide

Published

on

Peter Geelen and Jan O. Voogt, together with Peter van Weel, were there at the beginning of the work on Het Nieuwe Telen (New Work). This year, a special edition of a magazine* celebrates fifteen years of the concept. Both Peters and Jan laid the foundations for Land Appropriation, the framework that underpins Het Nieuwe Telen. Plant Empowerment is the English term that has gained worldwide recognition for this philosophy.

In 2022 the founders created the Plant Empowerment Academy. Their aim is to support the sustainable development of greenhouse horticulture by promoting an open exchange of knowledge through an objective and independent breeding concept.

On the Plant Empowerment Academy website, the founders discuss how the concept came about. Their story goes back to 2004, and they describe it as the beginning of the “sustainability transition in Dutch horticulture”. That year, the first fully enclosed greenhouse in the Netherlands was built.

“Surprisingly, the plants in this closed greenhouse behaved very differently from what theory and experience in conventional open greenhouses would have us expect,” they recalled. “For example, the rate of crop transpiration, which depends on solar radiation and humidity, did not fit standard evaporation models. Higher greenhouse temperatures sometimes produced better results than lower temperatures, which contradicted prevailing assumptions.”

New insights through the combination of physics and plant physiology
These unexpected observations inspired a new research project on plant behavior in relation to greenhouse climate. Peter van Weel, then working at Wageningen University and Research, and Jane, at Hoogendoorn Growth Management, conducted the research.

“We discovered that some long-standing theories about plant behavior and climate control were partly incorrect, and even contradicted the basic principles of physics and plant physiology. Step by step, together with researcher Peter Geelen, we developed a new growing concept based on physiological and physical laws. 2008.”

Other key milestones in the development of the concept were 2009, when Het Nieuwe Telen’s innovation program began, 2015, when Peter Geelen, Jan O. Voogt and Peter van Weel published the book ‘De basisprincipes van Het Nieuwe Telen’, and 2016. It starts from the natural behavior of plants and their inherent growth potential.

In 2018, a book in English followed, ‘Plant Empowerment, the basic principles’. The book was later translated into Dutch and Spanish. Today, the Plant Accreditation Academy manages the publication of all the books.

The founders of Plant Empowerment advocate close and open collaboration between all parties involved, including research and training institutes, extensionists and breeders, investors, suppliers, crop advisors, technical specialists, governments and other organizations. They emphasize that this intensive cooperation is essential for success. Plant Appropriation, they say, offers the fastest route to a sustainable and profitable global greenhouse industry. For more details, readers are directed to the Mission page of the Plant Empowerment Academy website.

In order to maintain the independence of the Plant Ownership Academy, the founders have stated that they cannot enter into commercial relations. Plant Empowerment Academy and Plant Empowerment Foundation are different organizations.

The Plant Empowerment Academy is, however, open to welcoming ambassadors who wish to contribute to their shared mission. Companies, institutes, distributors and organizations interested in joining the Academy as Ambassadors are invited to contact the founders through the Ambassadors page.

Plant Empowerment Digital Growth
In recent years there has been a growing interest in data-driven breeding, supported by modern computational tools such as artificial intelligence. According to the creators, the concept of Plant Empowerment is very suitable for this, as it is based on the physiology and physical principles of plants. At the same time, the sector increasingly feels the need for a unified monitoring protocol that can be used in both research and practice.

With the initiative and support of Kas als Energiebron, the authors published an additional guide at the end of 2023 called Plant Empowerment Digitaal Telen. This guide describes a structured method of crop monitoring, including the use of appropriate sensors and plant observations. It also explains the digital tools needed for practical implementation, such as dashboards. This uniform and standardized approach improves collaboration between different parties and facilitates the exchange and comparison of research and practice results. It also allows for a significant acceleration of the learning curve and overall sustainability transition.

Redefining the standards of UK cannabis

Published

By

Dalgety Ltd has entered into a partnership with Curaleaf Laboratories to supply pharmaceutical grade cannabis medicines to the UK cannabis market. The arrangement combines Dalgety’s cultivation operations, which are certified to EU-GMP standards, with Curaleaf Laboratories’ pharmaceutical manufacturing and distribution capabilities. According to the companies, this creates a UK-based supply route that does not rely on imported cannabis flowers, as Dalgety cultivates its product in-house. Dalgety claims it was the first company in the UK to grow, manufacture and supply EU-GMP medical cannabis from a single site.

The growing facility, which is more than 30,000 square feet, is located indoors and uses hydroponic growing methods along with automated lighting, irrigation, humidity and temperature control systems. The company reports that it uses AI-assisted environmental monitoring, which extends the traceability of batches to the final product and compares them to operating standards for air filtration systems. Post-harvest processing is said to follow EU-GMP protocols, including microbial and cannabinoid testing.

The stated goal of this approach is to reduce between-harvest variation in terms of THC and CBD content, terpene profiles, and microbial safety. Dalgety says his cultivation is overseen by staff with experience in horticulture and biochemistry, some of whom have worked on cannabis cultivation projects internationally.

Through a partnership with Curaleaf Laboratories, Dalgety’s UK-grown cannabis is processed and distributed through a UK-based supply chain, rather than imported from overseas. Companies suggest that this arrangement can shorten the time it takes to get products to market compared to importing, and reduce the likelihood of supply disruptions. Because Dalgety and Curaleaf Laboratories are involved in cultivation, manufacturing and distribution, the companies say this oversees the product at every stage, making it clearer for prescribers to see where and how the product was made.

Dalgety operates to EU-GMP standards and has been subject to regulatory review by the MHRA and the Home Office. Its operations include environmental monitoring, microbial testing, stability testing, controlled drying and curing procedures and quality assurance processes, along with controlled and secure facilities.

The company describes its work as controlled environment farming, hydroponic systems, environmental control technology, and efforts to stabilize cannabis genetics and phenotypes for batch-to-batch consistency.

Dalgety has also opened its cultivation facilities for visits to healthcare professionals, clinicians, pharmacists, researchers and other industry stakeholders. The company says this is in response to the fact that much of the cannabis historically supplied to UK patients has been grown overseas, which has limited opportunities for UK clinicians to see first-hand the cultivation and quality control processes. These tours aim to provide visitors with information on cultivation standards, EU-GMP compliance procedures, environmental control systems, testing processes and the regulatory framework governing cannabis manufacturing in the UK.

Dalgety and Curaleaf Laboratories describe their partnership as expanding access to UK-grown medical cannabis, improving supply chain reliability and helping to meet sector regulations, placing it in the wider context of growing demand for cannabis-based treatments from UK patients.

Arkansas GOP Governor And Democratic Challenger Agree On Opposing Marijuana Legalization

Published

By

“Giving more access to drugs, especially recreational access, does nothing to help or benefit Arkansans.”

Antoinette Grajeda, Arkansas attorney

Contains medical marijuana It generated more than $1 billion since Arkansas voters legalized it in 2016

After the state opened its first dispensary in 2019, thousands of Arkansans joined the program and spent a record $291.1 million on medical marijuana in 2025, according to the state Department of Finance and Administration.

Tax revenue from those sales now supports free breakfast for public school students after lawmakers passed legislation last year.

Medical marijuana programs have expanded across the country, as has recreational marijuana. Two dozen states, including neighboring Missouri, allow recreational marijuana use, according to state legislatures.

Arkansas voters rejected an effort to legalize recreational marijuana in 2022despite the national teams spending millions in support of the measure.

Restrictions on marijuana have been relaxed at the federal level, and the US Department of Justice earlier this year downgraded the drug classification of medicinal cannabis.

Here’s what Arkansas’ gubernatorial candidates — Democratic State Sen. Fred Love, Republican Gov. Sarah Huckabee Sanders and Libertarian Colt Shelby — have to say about legalizing recreational marijuana.

Democratic State Sen. Fred Love

Love said he opposes legalization during a debate at the Arkansas Press Association’s annual conference in June.

Sitting in a crosswalk at her daughter’s school, Love said “marijuana is all over” as the children exited their vehicles. When you grow up in a community where recreational marijuana is present, you see that it doesn’t always have a positive effect, he said.

“I don’t think it’s something I support,” Love said. “I’ve seen the long-term impact.”

While he doesn’t personally support it, Love said he would support legalizing recreational marijuana if Arkansans voted on it.

Libertarian Colt Shelby

Shelby said he’s for whatever Arkansans want, so he would support legalizing recreational marijuana if voters approve.

Shelby said the state’s elected officials have forgotten what matters most is what Arkansans want, which is why she’s running for office.

Although Shelby says she doesn’t smoke weed herself, she says almost everyone knows it and she has the meds.

“It brings a lot of good things, so I won’t say that I’m against it, but let the people decide”, he said in the debate in June.

Republican Governor Sarah Huckabee Sanders

Sanders did not participate in the June debate, but said in an emailed statement that he does not support the legalization of recreational marijuana.

“Giving more access to drugs, especially recreational access, does nothing to help or benefit Arkansans,” Sanders said.

Sanders vetoed a law passed by the Legislature last year dispensaries have been allowed to deliver orders via a delivery vehicle or drive-through window.

The governor signed into law in 2023 the bill protecting the rights for medical marijuana patients and caregivers to obtain a license to carry a concealed handgun.

In 2025, Sanders backed that uses medical marijuana revenue to support free breakfast for all public school students.
