Coco Coir Block 70+30 Low EC – Pressed natural substrate that yields up to 70 liters

Natural compressed and dehydrated coconut fiber in 4 kg blocks

Transporting large bags of substrate, dealing with compacted soil, or experiencing drainage problems are common difficulties for both professional growers and plant enthusiasts. The increasingly popular solution in nurseries, urban gardens, and hydroponics is compressed and dehydrated coconut fiber.

The GardenWeb 70+30 Low EC coconut fiber block offers a clean, lightweight, and extremely efficient alternative. At first glance, it looks like a compact block of just 4 kg, but when hydrated, it expands to about 70 liters of ready-to-use coconut substrate.

This means less weight to transport, more growing volume, and a high-quality substrate for roots.

Additionally, being Low EC coconut fiber, the material has been washed to reduce salts, ensuring a safe root environment for delicate crops, seedlings, or hydroponic systems.

🌱 A natural substrate that enhances plant growth

Coconut fiber for plants has become one of the most widely used substrates in modern horticulture due to its perfect balance of water retention, aeration, and structural stability.

Its fibrous structure works similarly to a natural sponge: it absorbs water when needed and gradually releases it when the plant requires it.

That's why it's an excellent base for:

• Universal substrate mixes
• Potted plant cultivation
• Urban gardens
• Hydroponic systems
• Nursery production

Thanks to its compressed format, this dehydrated coconut block for plants allows storing large quantities of substrate while taking up very little space.

✅ Real benefits of Low EC coconut fiber

Beyond being a simple organic substrate, coconut fiber provides technical advantages that make it a highly efficient growing medium.

High water retention capacity

Compressed coconut fiber can absorb a large amount of moisture and release it gradually.

This allows for:

• Maintaining stable moisture in the substrate
• Reducing watering frequency
• Improving water availability for roots

That's why it's ideal for potted plants or urban gardens where daily watering can be challenging.

Excellent aeration and drainage

Unlike many traditional soils, coconut soil does not compact easily.

This promotes:

• Constant oxygenation of roots
• Better root development
• Lower risk of waterlogging

Thanks to this, coconut substrate helps prevent problems such as root rot or fungal growth.

Low EC: low conductivity and absence of salts

One of the most important factors for professional growers is low electrical conductivity (Low EC).

This means that the coconut fiber has been washed to remove sea salts, ensuring:

• A clean and stable substrate
• Greater safety for seedlings and delicate crops
• Compatibility with controlled fertilization

That's why it's an excellent choice for hydroponics or intensive cultivation.

Neutral pH ideal for most plants

The pH of coconut fiber typically ranges between 5.5 and 6.5, making it a suitable base for a wide variety of crops.

This allows it to be used for:

• Indoor plants
• Ornamental crops
• Urban gardens
• Horticultural production

Additionally, being a light organic substrate, it facilitates the creation of custom mixes with perlite, peat, or compost.

High logistical efficiency: 4 kg that become 70 liters

One of the biggest benefits of this product is its extraordinary weight-to-volume ratio.

A 4 kg coconut fiber block yields up to 70 liters of hydrated substrate.

This means:

• Much easier transportation
• Less storage space
• Higher yield per unit purchased

This is why many growers prefer compressed coconut blocks over conventional soil bags.

👥 Who is this coconut block recommended for?
