NUTRIFIELD Coco Mega Brick 5kg Compressed Coconut Coir — Expands to 55L, Pre-Buffered Low-EC Growing Medium

NUTRIFIELD Coco Mega Brick 5kg is a densely compressed, pre-buffered coconut coir block that hydrates into about 55 liters of clean, ready-to-use growing medium for indoor and outdoor plants.

Designed for growers who need a high-volume, reliable substrate, this 5 kg Mega Brick maximizes storage efficiency and minimizes prep time. Rigorously processed, triple-washed, and calcium-buffered, the block offers a low electrical conductivity (EC) and consistent texture that supports healthy root development and precise nutrient management. It’s ideal for hydroponics, greenhouse production, container gardening, and any scale-up where space, cost, and substrate quality matter.

How much substrate will I get from one 5 kg brick?

When fully hydrated, the compressed 5 kg brick expands to approximately 55 liters of loose coco coir. That volume is sufficient to fill multiple standard pots or several grow trays, depending on their size and depth.

• Expansion: ~11x by volume — 5 kg expands to ~55 L
• Coverage example: fills roughly 11 medium 5 L pots or several 40×40 cm grow trays
• Hydration time: rapid soaking; ready-to-use after full absorption and fluffing

What makes this coco coir different from cheaper bricks?

NUTRIFIELD’s Mega Brick is horticultural-grade and undergoes triple washing and buffering to remove excess salts and stabilize cation exchange. The result is a low-EC, uniform substrate with consistent particle size and structural stability for better root airflow and moisture holding.

• Triple-washed to reduce salts and impurities
• Pre-buffered with calcium for stable nutrient uptake
• Consistent particle structure for reliable water/air balance

How should I prepare and use the brick for best results?

Hydrate the brick in clean water, allow complete expansion, then gently break up and aerate the coir to restore friability. Use as a stand-alone growing medium or mix with perlite or compost for specific drainage or nutrient needs; always check pH/EC before planting or starting a nutrient solution.

• Hydration: fully submerge in water and wait until volume stabilizes
• Fluffing: manually separate fibers to increase air porosity
• Testing: measure pH and EC; adjust nutrients as required for crop

Is the Mega Brick suitable for hydroponics and outdoor planting?

Yes — the low-EC, buffered nature of this coir makes it compatible with hydroponic systems, ebb-and-flow trays, and container gardening outdoors. Its balance of moisture retention and oxygenation supports diverse cultivation methods without the variability often found in unprocessed coir.

• Hydroponics: stable medium for consistent nutrient delivery
• Containers & raised beds: retains moisture while providing aeration
• Large-scale operations: compact shipping reduces logistics costs

Who is this for? Growers who prioritize consistency, storage efficiency, and clean substrate performance will benefit most: commercial greenhouse operators, serious hobbyists scaling up their grow space, and hydroponic growers looking for a bulk, pre-buffered coir option. If you need a dependable, neutral base to build nutrient programs on, the NUTRIFIELD Coco Mega Brick 5kg delivers volumetric value and predictable behavior.
