GrowGeneration’s Char Coir Introduces Next-Generation Propagation System to Enhance Cultivation Performance

DENVER, March 24, 2026 (GLOBE NEWSWIRE) -- GrowGeneration Corp. (NASDAQ: GRWG) (“GrowGeneration,” “GrowGen” or “the Company”), one of the nation’s largest suppliers of specialty products for controlled environment agriculture (CEA), commercial cultivation, and retail garden centers, today unveiled two new propagation products under the Char Coir brand, the Coco Coin Tray and the Insert Tray, offering gardeners, commercial growers, and greenhouse operators a modern, mess-free system for improved cultivation performance compared to traditional soil or peat-based methods.

Built for both home gardeners and commercial cultivators, the new Char Coir Propagation System expands GrowGen’s proprietary brand offering in growing media and propagation, reinforcing the Company’s strategy to drive higher-margin sales through differentiated, in-house product innovation. The new system is designed to provide a cleaner, more efficient solution for seed starting and early-stage plant development across both commercial and consumer applications.

"Most growers want the same thing: better starts, less transplant shock, and healthier plants," said Michael Leone, Founder of Char Coir. "The Coco Coin Tray and Insert Tray give them a simple, scalable solution that expands with water and creates the ideal environment for early root development, without the mess of soil and without the sustainability concerns of peat."

“Propagation is a critical stage in the cultivation cycle, and growers are increasingly focused on consistency, efficiency, and scalability,” said Darren Lampert, GrowGen’s Co-Founder and Chief Executive Officer. “The introduction of the new Char Coir Propagation System reflects our commitment to developing proprietary products that improve grower outcomes while supporting our long-term margin expansion strategy.”

A Scalable, Peat-Free Propagation Solution

The Char Coir Propagation System is engineered to address key challenges in early-stage cultivation by promoting faster root development and reducing transplant stress. The system offers a simplified, user-friendly three-step process in which growers add water, insert seed or clone, and transplant into the final growing medium.

The Coco Coin Tray is pre-filled with 50 compressed, RHP-certified coco coir plugs that expand with water to create a uniform, aerated growing medium. The coir is triple-washed for low salt content, buffered for stable pH and low electrical conductivity, and sourced from a single origin to ensure consistency.

The Insert Tray is a durable, reusable 50-cell propagation tray designed for repeated use in commercial environments. Compatible with a range of grow media including coco coir, peat plugs, and rockwool, the tray fits standard 10x20 flats and incorporates features that support propagation efficiency.

The Coco Coin Tray and Insert Tray are being introduced as part of a broader retail merchandising program designed to support sell-through at garden centers and hydroponic retailers. Both products are available through GrowGeneration’s retail locations, e-commerce platform, and distribution network, as well as through select retail partners nationwide.
