Open Tops

Max Volume Open Tops

High-Capacity Cultivation Bags for Permanent & Perennial Crops

Our Max-Volume Open-Tops are the premier choice for growers moving away from traditional pots and into high-efficiency hydroponics. Specifically engineered for large-root-volume crops, these bags combine a durable UV-treated outer shell with a custom-blended coir interior. From small-scale test plots to massive blueberry plantations, our Open-Tops provide the stability and longevity required for multi-year harvests.

Our Grow Slabs are most suitable for:

The Blueberry Gold Standard

The balanced physical structure of our slabs encourages roots to spread horizontally and vertically within seconds of planting.

Large-Scale Root Volume

Available in high-capacity formats from 25L to 85L, giving your plants the room they need to thrive without becoming root-bound or stressed.

UV-Stabilized Longevity

Our bags are manufactured with high-grade, UV-treated plastic designed to withstand harsh greenhouse heat and intense field sunlight for multiple seasons without degrading.

Advanced Drainage Control

The “Open-Top” design, paired with our bespoke coir-chip blends, ensures rapid vertical drainage. This prevents salt buildup and keeps the root zone oxygenated even during heavy fertigation.

Bespoke Volumes & Dimensions

We don’t do “stock only.” We customize the bag height, width, and total volume to fit your specific benching or field spacing, ensuring maximum plant density per acre.

Precision Material Blending

Choose the perfect ratio of Cocopeat to Coco Chips. Whether you need a water-heavy mix for hot climates or a high-chip mix for maximum aeration, we blend to your exact specifications.
