Grow Bags with Coco Substrate Slabs & Bulk Coir .

Commercial Coco Peat Slab Grow Bags & Custom Substrate Mixes

Berri Coir Factory manufactures and directly exports premium, 100% organic coco peat grow bag slabs designed for high-yield commercial horticulture. Compressed inside heavy-duty, UV-stabilized polyethylene bags, our grow bags offer optimal air-to-water ratios, structural durability, and rapid root expansion.

Engineered for precision hydroponics, greenhouses, and polyhouse farming, our grow bags come pre-drilled for drip emitters and plant slots, offering a ready-to-use substrate solution tailored to your exact crop requirements

Production & Processing:

Material: Aged and washed coir pith blended with premium husk chips

Processing: Screened and sieved to remove fine dust particles and long fibers for precise consistency.

Compression & Packaging: Compressed at an $8:1$ ratio into slabs in customizable dimensions, sealed in heavy-duty, UV-stabilized poly bags.

Quality Control & Testing Standards:

Raw Material Testing: Every incoming lot is tested prior to production.

In-House Lab Checks: EC, pH, moisture content, impurity levels, and sieving consistency.

External Accredited Lab Testing: Heavy metals, pesticide residues, bacterial counts, and fungal spores.

Custom Blend Options for Precision Farming

We offer custom-tailored substrate formulations to match specific crop root structures and climate conditions:

Slab Blend 70/30 (70% Coir Pith / 30% Husk Chips): Our most versatile mix. Combines high water holding capacity with chip-driven drainage. Ideal for vine crops like tomatoes and cucumbers.

Slab Blend 50/50 (50% Coir Pith / 50% Husk Chips): High-drainage, ultra-aerated mix designed for high-humidity climates or frequent fertigation schedules. Excellent for bell peppers and strawberries.

Husk Chip Special (100% Husk Chips / Heavy Fraction): Maximum air porosity and structure stability for perennial crops, orchids, and long-term berry cultivation.

Buffered Substrates: Pre-treated with Calcium Nitrate to displace Potassium and Sodium ions, stabilizing the substrate for immediate, nutrient-sensitive planting.

Ideal Commercial Applications

Commercial Greenhouse Hydroponics: Vine crops (Tomatoes, Bell Peppers, Cucumbers, Eggplants).

Soft Fruit & Berry Cultivation: Strawberries, Blueberries, and Raspberries in trough or gutter systems.

Cut Flowers & Floriculture: Roses, Gerberas, and Carnations requiring high aeration.

Vertical & Urban Farming: Lightweight, clean, and disease-free rootzone media.

Usage & Installation Instructions

Layout Slabs: Position the dry grow bags on your greenhouse gutters, floor channels, or support benches

Pre-Drip Setup: Insert drip fertigation emitters into the designated drip holes or top surface of the bag

Hydration & Expansion: Flush with clean water or a light nutrient solution (0.8-1.0 EC) until the coir slab completely expands to fill the outer bag envelope

Drainage Slits: Make small vertical slits on the bottom-side edge of the bag (if not pre-punched) to allow excess water run-off and prevent waterlogging.

Planting: Insert young transplants, tissue-culture plugs, or nursery cubes directly into the pre-cut plant slots
