Large Dutch greenhouse grower turns energy volatility into opportunity

Published

on

Volatility in energy prices continues to affect greenhouse gas producers across Europe, as the growing share of renewable energy and developments in electricity markets lead to stronger and more frequent price increases. For a large Dutch greenhouse grower, this challenge became the starting point for a more flexible and efficient approach to lighting management.

Like many high-intensity greenhouse operations in the Netherlands, the business faced rising electricity costs and major surprises while requiring precise light control to maintain consistent crop quality throughout the year.

To meet these challenges, the manufacturer implemented the Netvion intelligent control system. The solution enables real-time control of light intensity and spectrum without the need to rewire or make major changes to the existing greenhouse infrastructure.

Responding to extreme electricity prices
Electricity prices in the Netherlands have shown considerable volatility in recent years, ranging from negative prices during periods of renewable overproduction to sharp peaks in demand. “Traditional wired lighting systems offer limited flexibility to respond to rapid price changes,” says Sharan Avati with Netvion. “This often results in inefficient energy use and higher operational costs.”

With Netvion’s system, the grower can dynamically adjust lighting levels based on real-time electricity prices. During high price periods, light intensity is reduced to the minimum level required for crop development. When prices are low or negative, lighting levels can be increased to support plant growth, taking advantage of favorable market conditions.

Improve crop yield through clear precision
High-value greenhouse crops require precise control of light intensity at different growth stages. Using Netvion’s multi-channel lighting control, the manufacturer fine-tuned light levels from 30 µmol/m²/s at high prices to 200 µmol/m²/s when energy costs were low.

This level of precision optimized energy consumption while maintaining consistent crop quality. Instead of increasing stem length, the cultivar saw a measurable increase in crop weight, reporting 3-7% heavier crops, depending on crop type and growing conditions.

According to the grower, this improvement was driven by better alignment of light levels to plant needs during favorable energy price windows, without overstressing the crop during high-cost periods.

Fast financial impact through the fast energy manager
The financial impact of the wireless lighting system was very dynamic. With a capacity of 3 MW to connect to the grid (“knip”), the producer uses Netvion to respond quickly to fluctuations in electricity prices.

Depending on electricity prices, it can be worth up to 1,500 euros received in a single 15-minute window, shares Sharan. “This emphasizes the importance of real-time control speed rather than fixed hourly savings.”

“Combined with the reduced installation and maintenance costs enabled by the wireless infrastructure, the system provided a strong business case and approximately a two-year return on investment, while also reducing cabling, labor requirements and overall system complexity.”

Easy integration into existing greenhouses
Although Netvion is designed to integrate with existing climate control platforms, this manufacturer followed a different approach. Instead of using a standard third-party climate computer, the company developed custom in-house software to handle the control logic and system connections.

Netvion’s open and flexible architecture enabled integration with this custom-built platform, allowing the producer to implement their own advanced control strategies, taking advantage of wireless high-resolution lighting.

Sharan: “For other greenhouse operations using commercial climate control systems, integration can be easier. This case demonstrates that Netvion supports both standard integration and highly customized control environments based on the grower’s operational configuration.”

Marijuana Has ‘Horrific Health Risks’ And No Medical Value, Former Trump Attorney General Claims

A former US attorney general who served in President Donald Trump’s first term says marijuana poses “tremendous health risks,” has no medical value and should not be rescheduled under federal law.

“Marijuana redistricting would create a false impression that it is safe, reduce penalties for illegally selling the drug, and provide a large tax windfall to those who legally supply it,” William Barr wrote in a Wednesday op-ed for The Washington Post, Kevin Sabet, CEO of the prohibitionist organization Smart Approaches to Marijuana. “That would be a disaster.”

The opinion comes as the Trump administration moves forward with cannabis reregulation.

According to an order issued in April by US Attorney General Todd Blanche, Marijuana products regulated by a state medical cannabis license were immediately changed from Schedule I As did marijuana products approved by the Food and Drug Administration (FDA) under Schedule III of the Controlled Substances Act (CSA).

an administrator The hearing is looking at the broader rescheduling of marijuanawith The Drug Enforcement Administration (DEA) has been tasked with advocating for cannabis reform highlighting the testimony about the medical benefits of marijuana and its relative safety compared to other substances such as alcohol and opioids. It included appearances by a Food and Drug Administration (FDA) scientist and a doctor from New Hampshire. Medical marijuana provides relief to pain patients and can serve as an alternative to opioids.

But Sabet and Barr, who served as Trump’s attorney general from 2019-2020, argued that “the evidence presented at the hearing did not support the rescheduling of marijuana” and instead “confirmed what decades of data have shown: raw marijuana has no scientifically established medical value and is highly susceptible to abuse.”

After the parties to the hearing have filed termination rights, the DEA administrative law judge overseeing the proceedings will make a recommendation regarding rescheduling, and the agency administrator will make a final decision.

DEA Administrator Terrance Cole only organizations and individuals opposed to marijuana reform have been invited to the hearing as a designated participant – telling supporters that they do not meet the definition of “interested person” to participate because they have not been “affected or prejudiced by any rule or proposed rule that may be issued.”

The former attorney general’s new opinion says “the stakes couldn’t be higher”, arguing that “marijuana today is more dangerous than ever” and that it is “addictive”, throwing out a list of alleged harm to mental and physical health.

“These unhealthy effects are a predictable result of a powerful and addictive drug being normalized, commercialized and marketed as a medicine,” Barr and Sabet say. “It would be one thing if marijuana had medical value. But there is no credible evidence that marijuana is an effective treatment for any medical condition, despite the millions of dollars spent trying to prove otherwise.”

The Department of Health and Human Services (HHS) published a 252 analysis in 2023 that concluded that marijuana had accepted medical value and should be rescheduled.

The new opposition piece also says that “rescheduling would unlock enormous revenue for the corporate marijuana industry by bringing it into a category that has not been covered by a longstanding reduction in federal drug tax deductions,” referring to a law known as 280E, which repeals Sections I and II.

“This, in turn, would allow the industry to spend even more on advertising and marketing to young people,” Barr and Sabet. he wroteArguing that “those who would lose this dragon in society are laying the foundations for another Big Tobacco”.

The Sabet organization, SAM, is one of several parties Challenging the Marijuana Redistricting Process which have been upheld by a federal Court of Appeals. those separate parts State attorneys general have filed lawsuits against cannabis reform, Opponents of marijuana legalization and a a cannabis-based biopharmaceutical corporation.

SAM’s lawsuit was signed by attorneys at Torridon Law PLLC, where Barr is a partner.

The team announced in January that it was Hiring Barr’s firm to fight cannabis rescheduling After Trump signed an executive order directing officials to quickly complete the process.

During the first Trump administration, Barr was accused by a Justice Department official Directing improper anti-company investigations into multiple cannabis company mergers– Accounting for almost a third of the division’s cases in 2019.

Several Democratic members of Congress introduced a resolution calling for an investigation into Barr’s possible impeachment, saying “abused the power of his office” to improperly investigate marijuana businesses while engaging in other allegedly illegal conduct.

How much red light does cannabis really need?

Published

3 weeks ago

on

July 26, 2026

By

When growers pull out two LED fixtures side by side, the first number they usually discuss is percent red. This is an easy specification to fix. They are efficient at producing red photons and incredibly efficient at photosynthesis, and cannabis eats away at the flower. So more red must be better, right?

Not so simple. Red is an input to a spectrum, and the spectrum is an input to a room. There is no single spectrum that wins everywhere. An indoor room pushes hard, a greenhouse that soaks up sunlight, a temperamental cultivar, and aggressive yields call for something different. Knowing what each light strip actually does allows you to choose a tool that fits your grow instead of one that just has a big number on the sales page.

Blue: structure
Blue (approximately 400-500 nm) gives shape to the plant. It maintains dense growth, strong stems, tight internodes and allows it to develop as desired. It also encourages stomatal opening, so the plant manages water and gas exchange better. Get blue and you’ve built a plant that can carry heavy flowers with no problem.

Green: access
Green was eliminated as the wavelength is “reflected” by plants. It turns out that it does a real job. Blue and red are absorbed above; the green goes deep into the fat and reaches the leaves that are never touched by the above photons. In a compact room, it’s the difference between plants photosynthesising from the top down and those that work only from the top. Green won’t replace your red or blue, but it does carry usable light where they can’t reach.

Red: engine
Red is the horse of the flower. It absorbs as efficiently as anything in the spectrum, and is responsible for most of the biomass you’re after. Redder generally means faster flower development, more weight and better efficiency per watt.

But red has a ceiling, and it’s tied to what you run. Push PPFD upwards with a heavy red spectrum and some cultivars begin to whiten at the top: the flower should be dense with pale, washed tips. Genetics, intensity, barrel temperature and your general environment all feed into it. If you’re using aggressive light levels, a lower red spectrum will buy you room before that becomes a problem, leaving you almost no photosynthetic punch to get it.

Far Red: More than Emerson
Far-red (700-750 nm) appears in more devices every year. It contributes little to photosynthesis on its own, but it moves plant morphology and works with red through the Emerson Enhancement Effect. Used properly, it helps to deepen the light, encourage uniformity of the canopy and encourage the response of the bloom. The key word is small. A touch of far red rounds out a spectrum; he’s not there to make a show.

Matching the red percentage with the room
Cannabis addresses the entire spectrum, not a line on a spec sheet. Reds cause flowers, but blues, greens and crimsons give the plant something it needs. Where you land in red refers to how you grow.

A lower red spectrum (30-40%) captures more blue and green, gives you better morphology, reduces the risk of photobleaching, and holds up when you’re running extreme PPFD. Moderate spectrum (40-55%) is the sweet spot in commercial greenhouses: strong photosynthetic efficiency, strong flowering, balanced growth. A high-red spectrum (70%+) makes the most sense in a greenhouse, where the sun is already giving you lots of blue and green and your supplemental light can cast effective red to fill the gap.

Where does the ETS MAX series fit in?
This is the thinking behind the JumpLights ETS MAX series. Instead of forcing a spectrum into each room, it rarely comes up because a greenhouse and a high PPFD indoor flower room are not the same problem.

  • ETS MAX 4C41% red: for indoor rooms operating at very high intensity, where photobleaching is a real risk. The wider, red bottom balance allows you to push the tops without overcooking them
  • ETS MAX 4A48% red: balanced internal spectrum that maintains high output while controlling bleaching.
  • ETS MAX 5B57% Red: A high-performance indoor option. Moderate red, marked with efficiency and flower at the same time, up to 3,450 μmol/s, with efficiency that holds the spectrum.
  • ETS MAX 7A76% red: built for the greenhouse. The sun already supplies blue and green, so this leans heavily on the complementary red, up to 3,900 μmol/s in the infrastructure most greenhouses already have in place.

Bottom line
Choosing an activity is not a competition for the highest red number. The winning spectrum is the one that matches your environment, your intensity, your genetics, and what you’re trying to produce. Combine spectrum, intensity, environmental control, light distribution and genetics, and you’ve got a lighting strategy. Keep a spec isolated and all you’ve got is a bright room.

The ETS MAX line was created around this idea: choose the spectrum of the room you actually have, indoor or greenhouse, and let the device work with your grow rather than against it.
