Providing a quick and easy solution for growers, this bag is lab-tested and proven to deliver accurate results over a large selection of crops — saving growers both time and resources. It can be used in greenhouse, indoor or open-field environments and makes for a clean, consistent, and scalable option for any kind of grower.

Open-Top Convenience and Smart Design

The Coirgro 3-Gallon EZ Open Top Bag features an open-top design that allows quick access to hydration and later planting. They enable fast deployment across both commercial and hobbyist grow operations. It is durable, breathable non-woven mesh fabric, which maintains structure and drainage during the entire growing cycle.

They arrive with already-cut holes, accommodating irrigation drippers that seamlessly connects to automated watering sytems. Once soaked through, the substrate expands fully, scattering within the bag and creating a solid porous area where plant roots can grow and provide them stability.

Proven CNBZBlend Root Medium

At the heart of this product is CNBZBlend, a scientifically formulated blend of coco coir, coarse chips, and supportive fiber. This mix is designed and field tested to provide perfect porosity, moisture retention, and drainage. It absorbs 8–10x its own volume in water and still allows air to penetrate to prevent root pathogens and oversaturation.

Depending on the crop and environment, growers can select unwashed, washed, buffered, or nutrient-charged blends. For larger-scale projects that require accuracy in root-zone management, we offer custom blends

Special Protocols for Quality Assurance and Manufacturing

All Coirgro 3-Gallon EZ Open Top Bags are made with RHP certified factories specializing in ISO 9001:2015 quality management. Before a batch of raw material is used, hikes were placed on stringent TA internal testing, international institutions test and verification to ensure it performs as expected, with test results public certain each substances are contaminant free.

The internal lab tests parameters such as EC, pH, moisture content, and consistency, whereas third-party labs check for heavy metals, pesticide residues, bacteria, and fungal spores. The pH and EC of the final product are kept low (within 5.8 to 6.5 pH and approximately 0.5 mS/cm) and is buffered and triple-wash if necessary. We batch-code every bag for complete traceability.

Wettability, Productivity And Crop Health

The 3-Gallon EZ Open Top Bag by Coirgro is made of 100% natural, biodegradable, chemical-free materials, which promotes sustainable agriculture. OMRI-listed for organic use, and contains no harmful microorganisms or weed seeds. Such a sterile environment makes way for ample roots to grow without being stressed by locked-out nutrients!

It has a large water retention rate, minimizing the need to irrigate, while its quick-draining structure prevents water-logging. The larger volume makes it perfect for later growth cycles, larger plants, and more advanced crops.

Simple Hydration and Setup

Hydrate the eubase with plain water, or when all conditions have been established, nutrient water to activate the substrate by bringing expansion to a halt and runoff. To use with dripper sticks, place in their slots, set to run 5 – 20 minutes depending on flow, and walk away! Once hydrated, the medium will expand to its full size to fill the bag and form a stable base for planting.

Scalability and Packing Performance

There are 45 cases per pallet and 900 units in a shipment of the Coirgro 3-gallon EZ Open Top Bag designed for commercial scale. With its consistent nature, long shelf life, and lab-proven efficacy — it presents a perfect option for large-scale, sustainable substrate solutions for growers.
