Professional lay flat grow bags with compressed coconut coir slabs for commercial greenhouse production. FibreDust 1-meter lay flat grow bags include compressed coir slabs that expand when hydrated to fill the bag. OMRI-listed for organic production. Available in True Blend (70/30 coir/pith) and Berry Blend (80/20 coir/pith) formulations optimized for different crop requirements and irrigation strategies.

Commercial Greenhouse Growing System

Lay flat grow bags are the standard for commercial greenhouse production of tomatoes, cucumbers, peppers, strawberries, and other high-value crops worldwide. The 1-meter length with three pre-cut planting holes allows efficient use of greenhouse space and simplified fertigation management. Use directly on greenhouse floors or with Dutch leach trays to capture and recycle irrigation runoff.

Key Features

• 1-meter length with 3 pre-cut planting holes
• Includes compressed coconut coir slab that expands to fill bag
• OMRI-listed for organic production
• Natural pH: 5.8-6.0 (ideal for most crops)
• Two blend options for different crop needs
• Compatible with Dutch leach tray systems
• Proven in commercial greenhouse operations worldwide
• Excellent root development and aeration

Blend Options

True Blend (70/30 Coir/Pith Mix)

Balanced moisture retention and drainage for versatile crop production. Retains more than one day's moisture supply while maintaining excellent drainage and aeration. The 70% coir fiber provides structure and air porosity, while 30% pith offers water retention. Ideal for tomatoes, peppers, cucumbers, and other fruiting vegetables in fertigation systems.

Berry Blend (80/20 Coir/Pith Mix)

Formulated specifically for strawberry production with higher pith content for increased moisture retention. The 80% coir fiber with 20% pith delivers the moisture strawberries require without waterlogging. Supports heavy berry production while maintaining proper root zone aeration. Optimized for strawberry fertigation schedules and nutrient requirements.
