Belgian Lettuce Grower De Glastuin Achieves Increased Production And Faster Growth Cycles Thanks To A Full LED Solution From Signify

December 17, 2020

Eindhoven, the Netherlands – Since the introduction of Philips GreenPower LED Toplighting Compact from Signify (Euronext: LIGHT), the world leader in lighting, many vegetable, fruit and horticulture growers have made the choice to fully equip their greenhouses with LEDs. By combining this LED lighting with the GrowWise Control System, it is possible to both control and dim the light, giving growers a high degree of flexibility. This solution has now also found its way into lettuce growing; De Glastuin in Belgium opted for 100% LED grow lights from Signify.

Each type of lettuce requires a different amount of light. Heat is also a limiting factor when growing lettuce. As a result, in many periods it is not possible to illuminate the crops because too much heat accumulates in the greenhouse. Thanks to LED lighting, which emits less heat, it is possible to light the crop for longer hours, resulting in a increased production and faster growth cycles. The combination with the GrowWise Control System also allows the lighting to be dimmed. For example, to keep the light intensity the same on sunny days while maintaining light uniformity or to prevent climate fluctuations.

This summer, lettuce grower De Glastuin expanded its existing 1.75 hectare greenhouse with HPS lighting by 0.75 hectares. In this new part of the greenhouse, Philips GreenPower LED Toplighting Compact is installed together with the GrowWise Control System. The modules in the new part of the LED greenhouse have an output of 1800 µmol/s and require only 520 W (3.5 µmol/J). They provide a light level of 90 µmol/s/m². De Glastuin is pleased with the high quality and longer shelf life of the lettuce."With Toplighting Compact in combination with the GrowWise Control System, we can automatically adjust the amount of LED light to the amount of daylight at any given moment. As a result, there are fewer fluctuations in light intensity during the day. The lighting is much more efficient, dimmable and it offers us flexibility by allowing us to provide less light at any time," says Wouter de Bruyn, business manager at De Glastuin.

"De Glastuin's choice of Signify reinforces our conviction that we have chosen the right approach to make it easier for growers to switch to LED," says Udo van Slooten, Business Leader Horticulture LED Solutions at Signify.

The first Toplighting Compact was introduced in 2019 as a 1-on-1 replacement of HPS lighting to enable an easy transition to LED. The Toplighting Compact can be mounted on an existing HPS connection. This saves time and money during installation. In new greenhouses, installation is even easier thanks to easy-to-install brackets. The universal design of this system gives growers the possibility to fully equip their greenhouse with LED lights or to change their current set-up into a hybrid system with LED and HPS lighting. Signify's Compact range is also equipped with optics with normal and wide beam angles. The wide beam angle is ideal for growers looking for optimal light distribution or for lower greenhouses, for example. For crops where a greater distance between the plant and the grow light is possible, the normal beam is a better option.

What Are The Pros And Cons of Hydroponics?

AUGUST 28, 2020

Hydroponics is a type of aquaculture that uses nutrients and water to grow plants without soil. It is an increasingly popular growing method in urban areas and regions with extreme climates. There are many benefits to hydroponics as an alternative form of agriculture, including fewer chemicals, higher yields and greater water efficiency. 

However, hydroponics is not a perfect solution. The initial setup is expensive, and the whole growing system is heavily dependent on access to electricity and a clean water source. Here are just a few pros and cons of hydroponics.

Pros

The benefits of hydroponics are myriad and include:

1. More Water Efficient

Growing plants can require a lot of water, and conventional agriculture is historically wasteful of this resource. For example, a single walnut requires almost 5 gallons of water, and an orange uses nearly 14 gallons. Globally, over 70% of freshwater is used for agriculture. 

Compared to traditional growing methods, hydroponic systems are much more water-efficient. Growing in a climate-controlled environment allows cultivators to use the exact amount of water required for healthy plants, without any waste. Overall, hydroponics utilizes 10 times less water than conventional agriculture.

2. Higher Yields

Since crops are grown in a climate-controlled environment, hydroponic farmers are not limited by extreme weather or annual rainfall, resulting in higher crop yields. There’s more control over the setup of the system, and crops aren’t limited to a specific growing season. 

Additionally, when comparing vegetables grown in soil, hydroponics can sometimes grow plants at up to 16 times higher density. Hydroponics allows growers to do this without using significantly more nutrients or other inputs. 

3. Less Space

Some crops require a lot of space, and many conventional forms of agriculture are inefficient when it comes to using land. For example, row crops like soybeans and corn take up most of the arable land in the United States, but the harvest is used mostly for livestock and processed food, not human consumption. 

In contrast, hydroponic systems focus on cultivating fruits and vegetables, providing nutrient-dense food for consumers without taking up significant amounts of space. Additionally, researchers at NASA are studying how to incorporate hydroponic systems for longer-duration space missions by providing the right balance of light, carbon dioxide, and water. 

4. Community Resilience

Many cities have significant food deserts, and access to quality and affordable items is significantly limited. Urban hydroponic systems enable communities to cultivate their own crops, increasing food security for vulnerable populations. 

While hydroponics requires significant operational costs, there is also some proof that it may be a possible solution for countries that struggle with food insecurity or need back-up options during months of extreme drought. 

For example, in the United States, many agricultural enterprises grow food in one region but ship it to another for consumption. Many rural communities struggle with access to healthy produce because of this. Hydroponics may help foster community resilience by setting up an accessible system.

5. Fewer Chemicals

Many advocates of hydroponic systems stress that hydroponics reduces the need for synthetic chemicals. Since plants are most often grown in greenhouses with strictly controlled environmental inputs, pest pressure is almost nonexistent. Considering the detrimental impact of pesticides on the environment, using fewer chemicals is a huge advantage for hydroponics compared to traditional growing systems. 

However, there is an ongoing debate regarding how to qualify hydroponic crops, and whether they are eligible for organic certification. According to the USDA, this refers to the care and maintenance of soil without chemicals. Since hydroponics do not use earth, many traditional organic growers feel that they are not eligible. Regardless of how crops are labeled, the fact that hydroponics uses fewer chemicals is a definitive advantage compared to conventional agriculture.

Cons

Despite the many positives, hydroponics also has some challenges to overcome.

1. Technology Reliance

Hydroponics is a high-tech process. Most commercial operations utilize specialized equipment that regulates water temperature, as well as acidity and nutrient density. Because plants are cultivated in a completely climate-controlled environment, there is a significant reliance on technology. Hydroponics is considerably more high-tech than other growing methods, and there is an opportunity in agtech to improve yields and decrease inputs. However, the amount of tech also makes it cost-prohibitive for beginning growers.

2. Initial Investment

The hydroponics market is expected to grow from $9 billion to $16 billion in the next five years, so there is certainly an opportunity for investors to consider vertical farming as a viable operation. In traditional agriculture, is it hard for new and beginning farmers to get started, as many face difficulties with land access and infrastructure investments. 

However, getting into hydroponics is not necessarily any easier or cheaper. Despite a growing market, the initial investment in hydroponic systems is steep, especially on a commercial scale. For this reason, many of the largest growers are established agriculture corporations that already have capital in place. The initial investment limits profitable hydroponic operations to a few large farms, making it tricky for smaller growers to enter the market.

3. Organic Debate

As mentioned above, there is an ongoing debate in the farming community about whether hydroponic produce can be labeled organic according to USDA standards. Without a clear definition of the nutrient profile of hydroponics, nor stringent guidelines on which fertilizers or chemicals are permissible, many consumers remain cautious about hydroponic produce. This affects the industry’s success, as many consumers don’t know how crops are grown or what’s added to the water.

Without a clear definition from the USDA, there remains some question over self-labeling of hydroponic crops as organic when synthetic chemicals may still be added.

4. Equipment Requirements

While a home gardener can easily utilize some plastic bottles and storage containers to build a small hydroponic system, commercial farmers have significant equipment requirements. In addition to the initial costs of setup for infrastructure, there are also necessary and costly machines to consider. Pumps, tanks, and other controls can be expensive, not to mention electricity and access to filtered water.

5. Waterborne Diseases

While hydroponic systems may reduce or eliminate pest pressure, certain waterborne diseases are more prevalent in hydroponically grown produce. The most common ones affect the plant’s root structure, such as Pythium, which includes several water mold species. 

Proper hygiene and cleaning practices can reduce the risk of plant disease, but it is often impossible to avoid completely. Because of this likelihood, many hydroponic growers incorporate bio fungicides to prevent breakouts.

Soil-Free Growing

Hydroponic growing can increase crop yields while reducing water usage. The benefits of hydroponics are significant, and the industry is expected to grow astronomically in the next five years. However, there are also some disadvantages to growing hydroponically. Improving access to infrastructure and making technology more accessible will enable more beginning growers to enter the market.

For decades, consumers have been on a quest for cleaner, safer produce — and agricultural methods that are good for both the palate and the planet.

Bowery Farming, the New York-based indoor farming start-up, thinks it’s mastered the recipe, especially given increasing safety concerns.

Grown indoors, lettuces, greens, and herbs are non-GMO, free from pesticides “and grown with complete transparency,” says Katie Seawell, Chief Marketing Officer. “We are deeply committed to increasing access to high-quality delicious food. We’re going to build an enduring brand — we hope a generational brand — that emotionally connects with consumers.”

Its main selling point? “Our produce tastes better, too, and that means a lot to our core audience.”

At present, the vast majority of produce isn’t branded, “and highly commoditized, not unlike coffee used to be,” she says. “I spent 15 years at Starbucks before joining Bowery a year ago, and I see a lot of similarities. Starbucks is a very mission-driven company, and so is Bowery. We are committed to disrupting the food-supply vision. And through technology, we want people to think differently about how we grow the food we eat.”

Currently, Bowery is selling its products in retail chains such as Walmart, Giant, and Whole Foods Market. It’s also available on Amazon Fresh and believes e-commerce will be one of its biggest sources of growth. “It’s a great cross-section of retailers, and part of our goal-to democratize access to our produce.”

Seawell says it is preparing ads set to break later this year, based on consumer research that uncovered ongoing concerns about widespread lettuce recalls for problems like E. coli and Cyclospora infections.

Mustache is the ad agency, and it also worked with Red Antler for a brand refresh and a new website.

Seawell says the pandemic has also intensified interest in safer, healthier foods. It’s also accelerated awareness of America’s gaping inequalities and inefficiencies in the food system.

So far, Bowery has two farms in Kearny, New Jersey, and the a outside of Baltimore. With its modular technology, it hopes to expand soon. Providing fresh food for underserved communities is also part of its mission, which translates into partnerships with nonprofits, including DC Central Kitchen and Table to Table.

Correction: An earlier version of this story misspelled CMO Paula Seawell’s name, as well as the location of two of its farms. They are in Kearny, New Jersey.
