William Attardi on April 9, 2025

Sollum® announced its partnership with Gourma, a leading fine herb grower based in Saint-Norbert, Québec. Gourma offers 25 potted herb varieties, including nine that are certified organic. These aromatic herbs are distributed across Québec in the produce sections of grocery retailers, reflecting the quality and reach of their greenhouse production. In early 2023, Gourma undertook a major brand repositioning, doubled its production area, and adopted a forward-thinking vision focused on innovation. With the integration of Sollum’s dynamic LED lighting solution, the company is now making a significant shift towards a fully controlled and adaptable lighting environment. This collaboration will enable Gourma to precisely tailor lighting conditions to the specific needs of its herbs, influencing key factors such as morphology, colour, and flavour. https://www.ledinside.com/news/2025/4/2025_04_09_04

DLC Updates its Technical Requirements for LED-Based Horticultural Lighting

William Attardi on March 14, 2025

A new version of the DesignLights Consortium’s (DLC) Horticultural Lighting Technical Requirements released today strengthens efforts to improve the efficacy and quality of LED products used in the controlled environment agriculture (CEA) industry. Taking effect April 18, 2025, the DLC’s new requirements come at a time of burgeoning growth in the CEA sector. Valued at $7.8 billion last year, the global CEA market is expanding at a compound annual growth rate of 12.2 percent and expected to reach $22 billion by 2033, according to a February 2025 market research report. With lighting being the largest operational expense in CEA facilities, there are significant opportunities to increase energy efficiency and cost savings with the right lights.

Sollum Technologies and Leaficient Introduce the First Plan-Responsive Dynamic LED Lighting Solution

William Attardi on March 8, 2025

Sollum Technologies and Leaficient are pioneering a breakthrough technology that redefines how LED lighting adapts to plant growth. Today’s traditional lighting strategies rely on Daily Light Integral (DLI) as the primary metric for optimizing plant growth, based on the premise that plants absorb and use light with the same efficiency throughout the day and at all growth stages. However, recent research has shown that plant productivity can change significantly based on a myriad of factors relating to the environment, resources provided and internal biological processes. In response, Sollum and Leaficient are collaborating to develop the first closed-loop, plant-adaptive dynamic lighting system, which adjusts lighting in real time based on plant productivity and growth rates.  [News] Sollum Technologies and Leaficient Introduce the First Plan-Responsive Dynamic LED Lighting Solution – LEDinside

DLC Draft 1 Horticultural Technical Requirements V4.0

William Attardi on December 31, 2024

The DesignLights Consortium (DLC) has released their Draft 1 Horticultural Technical Requirements V4.0. The draft proposes three updates:

  • Efficacy increase: Hort V4.0 proposes to increase the efficacy threshold to 2.5 μmol × J-1, which is an 8.7% increase over the Hort V3.0 threshold. This will set the DLC efficacy threshold for LED-based horticultural lighting at more than 45% above the most efficacious non-LED option.
  • Removal of lamp categories: Hort V4.0 proposes to remove eligibility for lamps. This decision was made based on low application numbers in lamp categories.
  • Clarifications to various requirements: A variety of clarifications are proposed throughout Hort V4.0, including for definitions of key terminology and for certain testing requirements.

The Draft 1 Horticultural Technical Requirements V4.0 document is available here.

Key Themes of Washington’s Farewell Address 

Crafted with the assistance of his close advisors, including Alexander Hamilton and James Madison, President George Washington’s Farewell Address was intended to offer guidance and warnings to the American people as they faced the challenges of the future. Among the most significant themes were:

  1. Neutrality in Foreign Affairs – advising that the United States should avoid becoming involved in the conflicts and political machinations of foreign powers. He argued that such alliances could lead to unnecessary entanglements and could jeopardize American interests and independence.
  2. The Dangers of Political Parties – Washington expressed concern that political factions could lead to divisions within the country and weaken the unity of the nation. He believed that political parties could become sources of discord and could prioritize their own interests over the common good. He encouraged Americans to work together for the benefit of the nation as a whole.
  3. The Importance of National Unity – He emphasized that the strength of the United States depended on the unity of its people and the coherence of its government. Washington urged Americans to set aside regional and political differences and to work together to build a strong and prosperous nation. Source: Day in History
