HortGrow Coco Blend Bag — 1.5cu ft — 90% Coco Pith / 10% Coco Fiber

HortGrow Coco Blend Bag — 1.5cu ft — 90% Coco Pith / 10% Coco Fiber

HortGrow Coco Blend Bag is a professionally processed, ready-to-use coco coir growing medium formulated with a moisture-optimized 90% coco pith / 10% coco fiber blend that delivers excellent water retention, uniform moisture distribution, and a biologically active growing environment straight from the bag. The high coco pith content provides the water-holding capacity and consistent capillary moisture movement that plants need for steady hydration between irrigation events, while the 10% coco fiber fraction adds structural support and improves the long-term stability of the growing medium throughout the crop cycle.

Triple-washed and calcium-magnesium buffered, the HortGrow Coco Blend Bag is designed for immediate use — no mixing, measuring, or additional preparation required beyond a pre-planting flush to verify EC. The 1.5 cubic foot bag size is practical for filling multiple containers per bag or completely filling larger individual growing vessels.

Key Features & Benefits

• 90% Coco Pith / 10% Coco Fiber Ratio: The pith-dominant blend delivers superior moisture retention and consistent capillary water distribution — ideal for growing environments where maintaining high substrate moisture between irrigation cycles is important, or for crops with moderate to high water demand throughout the growing cycle.
• Triple-Washed & Buffered: HortGrow's multi-stage washing and calcium-magnesium buffering process removes excess soluble sodium, potassium, and salts from the raw coco fiber — delivering a clean starting EC and near-neutral pH with minimal pre-use preparation required.
• Ready-to-Use Bagged Format: Pre-mixed and ready to pour directly into containers, grow bags, or soilless growing systems — no measuring, blending, or hydrating required. Saves preparation time in commercial growing operations and simplifies media setup for home growers.
• Biologically Compatible Growing Medium: Coco pith supports the development of a healthy beneficial microbial community in the root zone — providing a living biological environment that can improve nutrient cycling and root health when combined with microbial inoculants or organic nutrient programs.
• 1.5cu ft Practical Format: The 1.5 cubic foot bag size is a versatile choice for filling multiple smaller containers or a single larger growing vessel, providing a practical balance between volume and handling convenience.

Who Should Use This

HortGrow Coco Blend Bag is an excellent choice for indoor cultivators who want a simple, ready-to-use coco growing medium with a moisture-optimized pith- dominant formulation. It is well-suited for container growing, grow bag systems, and any soilless production approach where strong moisture retention and consistent coco quality are priorities. Growers who want to improve aeration can blend this product with perlite or coco chips to adjust the air-to-water ratio for their specific requirements.

Compatibility

Compatible with all hydroponic and organic nutrient programs. Flush with pH-adjusted water and verify runoff EC before planting. Can be blended with perlite (recommended at 20–30% by volume) to increase aeration for high-frequency irrigation programs. Also available in a pre-mixed 70/30 Coco & Perlite Blend for growers who prefer a pre-blended aerated formulation.

Frequently Asked Questions

What is the difference between coco pith and coco fiber?

Coco pith (also called coco peat) is the fine, sponge-like material found between the fibers of the coconut husk — it has excellent water retention and a large surface area for root colonization and microbial activity. Coco fiber consists of the longer, coarser strands from the husk — it adds structural stability and improves aeration slightly compared to pure pith, but retains less moisture. The 90/10 blend optimizes moisture retention while maintaining structural integrity.

Should I blend this with perlite for better drainage?

If your irrigation program involves infrequent watering or if your plants have high oxygen demand at the root zone, adding 20–30% perlite by volume will improve drainage and aeration. For high-frequency drip irrigation programs where the substrate stays consistently moist, the pure 90/10 coco blend may be used without additional perlite. HortGrow also offers a pre-mixed 70/30 Coco & Perlite Blend for convenience.

Does this product require additional buffering?

HortGrow's coco is pre-buffered during production, but it is still best practice to flush with nutrient solution and check runoff EC before planting. This confirms the media is fully primed and removes any residual buffering compounds from the surface of the coco fiber.

How many containers can I fill with 1.5cu ft?

A 1.5 cubic foot bag contains approximately 42 liters of growing media. This is enough to fill approximately four 10-liter containers, three 15-liter containers, or two 20-liter containers — the exact quantity depending on how firmly the media is packed and the specific container geometry.

Is this coco blend organic?

Coco coir is a natural plant-derived growing medium. HortGrow Coco Blend is made from coconut husk byproduct processed through washing and buffering — making it an organic-origin material compatible with organic nutrient programs. For certified organic production, confirm that the specific product meets your certifying organization's requirements.
