Professional Growing Media
OpenGrow™
Ready-to-Plant Open-Top Grow Bags for Professional Cultivation
Nordic Coir OpenGrow™ is a professional pre-filled open-top growing solution developed for commercial greenhouse and hydroponic production.
Combining carefully selected coco peat and coconut husk chips, OpenGrow™ creates a balanced root-zone environment with reliable moisture retention, aeration and drainage throughout the growing cycle.

PRODUCT OVERVIEW
A Smarter Root Zone, Ready When You Are
OpenGrow™ eliminates much of the preparation associated with loose growing media.
Each open-top grow bag is supplied pre-filled with a selected Nordic Coir substrate blend and prepared for straightforward installation in the greenhouse.
The combination of coco peat and husk chips helps create a stable balance between water availability and air-filled porosity, supporting healthy root development while allowing excess irrigation water to drain efficiently.
The open-top design also provides growers with easy access to the root zone and flexibility when establishing different crops.
Key Benefits
APPLICATIONS
Built for Modern Greenhouse Production
OpenGrow™ is designed for commercial growers requiring a controlled, repeatable growing medium combined with simple crop handling.
The substrate composition can be selected according to crop requirements, irrigation strategy and desired air-to-water balance.
TECHNICAL DATA
OpenGrow™ Professional Growing Bag Specifications
Lower EC specifications and alternative substrate configurations can be discussed for specialised commercial applications.
SUBSTRATE OPTIONS
Choose the Coco Structure for Your Crop & Irrigation Strategy
70/30 Coco Peat / Husk Chips
Higher coco peat proportion with added chip structure. An option where growers require a balance of moisture availability with additional aeration and drainage.
50/50 Coco Peat / Husk Chips
More open physical structure with increased chip fraction. An option for stronger drainage and root-zone aeration.
40/60 Coco Peat / Husk Chips
Highest chip proportion among the listed OpenGrow™ standard options. A more open substrate configuration for growing programmes requiring greater drainage and air space.
Final blend selection depends on crop, irrigation programme, greenhouse environment and grower requirements. Nordic Coir can discuss the appropriate substrate configuration based on the grower's existing system and trial requirements.
FORMATS & DIMENSIONS
Designed Around Your Growing System
Commercial greenhouses do not all operate the same way—and the growing medium should not force growers into a single configuration. OpenGrow™ can therefore be produced according to the dimensions and root-zone volume required for your cultivation system.

Whether you are developing a new greenhouse or evaluating alternatives to your current substrate system, Nordic Coir can work with your cultivation specifications.
CUSTOM SOLUTIONS
Your Crop. Your Irrigation. Your Root Zone.
OpenGrow™ is built around the principle that substrate performance should match the crop and the production system. Growers can select from different coco peat and husk chip ratios to create the appropriate balance between water retention, drainage and aeration.
For new commercial projects, we recommend evaluating the selected configuration under real greenhouse conditions before moving to full-scale supply.
PACKAGING & COMMERCIAL SUPPLY
Prepared for Efficient Commercial Handling
OpenGrow™ is designed not only for crop performance, but also for practical greenhouse operations. The growing medium is supplied directly inside a durable UV-treated outer bag, helping reduce substrate preparation and simplifying installation in the production area. Commercial orders can be palletised and configured according to customer requirements, greenhouse installation plans and transport efficiency. For larger projects, Nordic Coir can also support direct factory supply, customised packing configurations and scheduled commercial shipments to customers across Nordic and European markets.
WHY OPENGROW™?
More Than a Bag of Growing Media
Natural coir. Controlled structure. Practical greenhouse handling.
The result is a growing system designed to help commercial growers achieve a more consistent root-zone environment while simplifying substrate preparation and crop establishment.
For Nordic growers facing high production costs and demanding quality expectations, reliable substrate performance and operational efficiency matter. OpenGrow™ is developed with exactly that in mind.
