Making progress with substrate slabs and jute plugs

Published

on

This summer, some greenhouses in the Netherlands are trying to grow tomatoes, peppers and eggplant: the sheets of organic substrates made with jute. The Holand is an important step for bioproducts, which is a traditional greenhouse. So far, the company has had the greatest success with Jute-based substrates in hydroponics and vertical agriculture.

At Greentech Amsterdam, the Holland Bioproducts presented its range of products, for greenhouse crops, jute pads as well as microgreens and jute plugs. “Right now, our main focus is hydroponics and vertical agriculture,” says sales director Sales de Haan, talking from the company’s office at the World Horti Center.

Holland Bioproducts were founded in 2017, but it brings more than fifteen years of experience to process jute. With this experience, the company develops a high quality compostable alternatives, with traditional substrates like peats and rockwools. Their products are made from a specific part of the jute plant fibers, asian (combined with other European raw materials).

Elastic crop
Jute plugs have a unique conical form and sowing sowing, because they are designed to sow and disseminate hydroponic systems. Sometimes, while they need small adjustments, accessing existing configurations, large international customers are widely used, Arjen explained. Switzerland, the United Kingdom, the United States, Middle East, and Australia are successfully growing in the substrates of Holland bioproducts.

For microphen farms, the Holland bioproducts provides a completely organic blue line series, adapted to the pads, crop types and harvesting method, with or without roots.

The current movement of the more elastic crop is playing in the hands of the company. Piper production, increasingly increasingly changing alternatives from traditional substrates. For this market, Holland Bioproducts has developed a substrate sheet made with jute, mixed with miscthus and other herbs.

“It’s a really mix of organic fibers,” Arjen explained. “Jute gives strength, miscanthus adds aimena and the grass gives the volume. All components are sterilized to ensure safe crop.” Parts are more suitable than peppers, tomatoes and eggplants can also grow in them.

In collaboration with the manufacturers of the system
Holland Bioproducts entered worldwide as a recently participant and became a member of the Dutch Greenhouse Delta, a network that contains many technical suppliers. “It’s very valuable for us,” Arjen says. “We explore how to adapt the system manufacturers together to make sure the systems can operate successfully with our substrates.”

Within the Dutch Delta Greenhouse, it has become an active company in the Middle East module. “We see strong growth there, like the use of peat in the pressure under pressure, is another important region of Scandinavia, where the Middle East is a key sustainability driver.”

Footprint
To measure sustainability, Holand Bioproducts had its substrates evaluated by the universities and research of Wagening. “The results showed that our substrates are very well compared. Our footprint is significantly lower,” Arjen confirmed.

The numbers are very promising, especially for sheets used in fruit vegetables. “These slabs combine the grass and miscanthus. About 70% and 80% of raw materials help maintain a low footprint.”

Scaling with a slab
Holland bioproduces are making continuous progress with its plugs and microgreen substratum, following new tests on the vegetable substrate slab. Soon, they will meet the farms to review the results of the season. “So far, the crops are growing well. Lately in heat containers, the breeders did not need to add more irrigation,” Arjen says. Looking up to 2026, the Netherlands expects to test four growers, that the slabs will be expanded to use a larger scale, and other breeders will begin with smaller rehearsals.

Arjen explained that the initial phase of the farming requires special attention. The growers cannot use the same methods applied with old substrates. However, as they are testing more crops, the growers are beginning to see the benefits of changing alternative materials. An example of jute, after use is completely composting. “This saves money to throw money costs,” Arjen says. Jute has a lower environmental impact, requiring less water than coca, and is certified according to the regulation of fertility products (FPR).

Pre-cultivated slab
To fulfill the growing request and improve local availability, the Holland bioproducts is opening a new facility in the Middle East. Here, Jute will be sterilized and processed from India and Bangladesh, improving logistics and efficiency. In the future, the company also grows the opportunity to produce plugs on the site, helping to reduce costs even more.

“But first, our priority is to know more breeders to grow jute options,” Arjen says. It is an attractive product that can help you, the Holland bioprons has just added to its range. These slabs are aimed at other garden centers and other consumer vendors, but it is the surprise of Arjen, as well as interest in professional producers. “It really wasn’t something I expected,” he admits with a smile.

By

Ora Pharm has confirmed that New Zealand patients, prescribers and pharmacies continue to have uninterrupted access to Helius Therapeutics products following the successful acquisition of the business and its key assets, directly challenging the misinformation being circulated to patients and prescribers by cannabis importer MW Pharma Limited (trading as NUBU).

Industry monitoring was highlighted on Monday, July 20th, when Helius Therapeutics announced that NZ Grow Co. As he inaugurated Growers Day. The event demonstrated the full operational strength, advanced capabilities and integrated supply chain now fully operational under Ora Pharm’s leadership to support the growth of the NZ sector.

At the event, CEO Zoë Reece addressed concerns stemming from a July 9 industry bulletin distributed by NUBU, which stated that “Helius Therapeutics has ceased production and all products are now discontinued.”

Ora Pharm said the statement was incorrect and had the potential to create unnecessary uncertainty in a highly regulated healthcare sector.

“Inaccurate information about the availability of medicines can cause unnecessary worry for patients, prescribers and pharmacies, interfere with treatment decisions and undermine confidence in the New Zealand cannabis industry.”

Ora Pharm completed the business and acquisition of key assets of Helius Therapeutics on June 18, 2026, resuming manufacturing, packaging and nationwide distribution the following day. All Helius brand formulated products and locally grown products remain approved and available for patient supply.

CEO Zoë Reece said the company’s focus is on ensuring continuity of care while strengthening New Zealand’s medicinal cannabis industry.

“The Helius facility gives New Zealand growers direct access to world-class pharmaceutical drying, extraction and manufacturing capabilities. Combined with NZ Grow Co., we are creating a secure and integrated pathway from cultivation to finished products and international markets. Our focus is on clinical continuity, quality assurance and confidence in patients and prescribing physicians every day.”

California Treasurer Announces Hearing On Marijuana Business Banking Access Issues

Published

By

California’s state treasurer has announced he will convene a hearing next week to highlight the marijuana industry’s banking access “challenges” and its impact on businesses, workers and communities.

The hearing, organized by Treasurer Fiona Ma (D), comes ten years after her predecessor launched a Cannabis Bank Task Force to look into the issue.

Titled “Continuing the Conversation: Advancing Safe and Legal Banking for California’s Cannabis Industry,” Wednesday’s hearing will feature state and local officials, financial institutions and representatives of marijuana companies. The plan is to “review progress made, discuss remaining obstacles, and consider practical steps California can take to support a safe, transparent and well-regulated legal cannabis market,” Ma’s office said in a press release.

“Nearly a decade after the launch of the Cannabis Banking Working Group, California’s legal cannabis industry continues to face barriers to access to affordable and reliable financial services due to state-federal conflict,” Ma. he said. “This hearing it will help us assess what has changed, identify challenges that remain, and continue the conversation about practical solutions that support public safety, transparency, and responsible business operations.”

Last month, bipartisan members of the US House and Senate reintroduced the legislation protect banks from being penalized for providing financial services to marijuana businesses.

Previous iterations of the banking legislation have been introduced in previous sessions of Congress, and while the House of Representatives has passed versions on several occasions, the reform has never become law.

While some banks serve marijuana businesses, the continued federal illegalization of the plant has made many reluctant to work with the industry.

“Limited access may increase operating costs, complicate routine financial transactions, and require some businesses to handle larger amounts of money, creating additional security and administrative concerns,” Ma’s office said.

Peat is a lot more sustainable than we think

Published

on

By

Increasing public scrutiny has questioned whether the use of peat is environmentally sustainable. A new review According to Dr. James Altland, research director of the USDA’s Agricultural Research Service, and Dr. Bruce Bugbee of Utah State University, they present a more nuanced picture than much of the current evidence portrays.

“Much of the debate in the popular press suggests that the use of peat in horticulture is unsustainable because it causes global warming and other environmental impacts,” shares James. “We have seen that agriculture is much more sustainable than some parties in the media want us to believe.”

Differences between regions matter
The review states that assessments of peatland sustainability should differentiate between regions. While European peatlands have been heavily impacted by centuries of drainage and peat extraction, most Canadian peatlands remain undisturbed, with only a small proportion used for horticulture. According to the authors, this distinction is important when assessing the environmental impact of peat production.

“Currently, Canadian peatlands are sequestering carbon faster than the rate of extraction from container crop production. At current rates of extraction and with appropriate restoration, peatland use in North America is environmentally sustainable.”

The authors note that horticultural peat extraction in Canada accounts for only a small fraction of the total peatland area and that harvested sites are routinely restored after production.

Restoration supports long-term recovery
The paper highlights the role of restoration practices, particularly the Moss Layer Transfer Technique (MLTT), in restoring peat-forming ecosystems.

“Restoration techniques, such as the moss layer transfer technique, can turn harvested peatlands into carbon sinks over decades,” he added. The review found that restored peatlands can restore vegetation, biodiversity and carbon sequestration functions over time, while improvements in water storage and hydrological performance are also documented.

Alternatives also have environmental impacts
The researchers also looked at published life cycle assessments comparing them to substrates such as peat, korea, wood fiber, perlite and rock wool. “Life cycle assessments show that alternative substrates often have environmental impacts comparable to or greater than peat, especially when considering water use, transport and fertilizer inputs.”

The review concludes that comparisons depend on system limitations and assumptions, and that broad claims that alternatives are inherently more sustainable than peat are not consistently supported by published analyses.

Performance remains an important consideration
Beyond sustainability, the paper reviews the functional characteristics that have made peat the reference substrate for container production.

“Soil’s high cation exchange capacity, water retention and stability support optimal plant growth and nutrient uptake,” shares James. The authors point out that these properties contribute to efficient irrigation and fertilizer management, maintaining good root zone conditions.

Although wood fibers, coir, and other materials can reduce peat use in mixes, each introduces its own management considerations, such as nutrient immobilization, water use, or processing requirements.

Managing future demand
As the global demand for soilless growth media is expected to increase significantly in the coming decades, the authors believe that a variety of substrate materials will be required.

“At current rates of extraction and with appropriate restoration, peat use in North America is environmentally sustainable and remains essential for horticulture and urban greening.”
