Our choice for Best Coco Coir for hydroponics

Editor’s Choice: Harris Coconut Coir Pith​

• Manufacturer: Harris
• Weight: 5.57 pounds
• Dimensions: 8 x 4 x 8 inches

Harris Coco Coir is beneficial to the development of strong roots. If you want the nutrients to be distributed evenly throughout the soil or potting mix, use this as an additive. The addition of coco coir fiber to soil enables the soil to take on a more spongy and loose consistency by virtue of the coir’s characteristic fluffy texture.

Because it can absorb up to ten times its own weight in water, it makes maintaining adequate root hydration much simpler than ever before. Coir is an extremely versatile material that can be used for anything from growing plants in indoor pots to cultivating soil in an outdoor garden.

When you are ready to use the coir, soak one of the bricks in warm water so that the water can penetrate through the fibers. The coir brick will begin to absorb the water and expand as more water is added to the mixture.

Remember that this will balloon up to at least eight times its original size when it dries out. After the excess water has been drained off, you can use a trowel or your hands to separate the expanded fibers and get the desired quantity.

Coco coir for hydroponics FAQ​

Is coco coir good for hydroponics?​

What coco coir should I buy?​

Coco coir has been used for decades, but its popularity in hydroponics farming has recently increased. It is a growing medium that resembles soil but is made of coconut husks. The rope-like outer fibers that cover coconuts are fruit residue unfit for consumption.

However, those husks serve as an excellent growing medium and provide numerous benefits that make them suitable for hydroponics. Coco coir is a versatile and natural product known as coco peat or simply coco. Farmers appreciate that it is a sterile medium that does not contain harmful bacteria or fungi, making it ideal for hydroponics. Coco coir is extremely simple and does not require religious monitoring like other growing mediums.

Coconuts are primarily found in tropical areas near bodies of water. They frequently fall into such bodies of water, but the coconut’s outer husky layer protects their seed. The husk thus protects the inside and serves as a fertile medium for the seed to germinate. As a result, coco coir is an ideal medium for hydroponics.

Coco coir comprises three parts of the coconut: coco chips, coco pith, and fiber. The pith looks like peat moss and is highly absorbent. Before purchasing coco coir, make sure the pith has aged sufficiently to be used as a growing medium. If the pith is not aged correctly, it can release salts that can harm or wilt your plants.

It is critical to select a coco coir manufacturer who is open about their product information and has properly aged the pith. Buyers should purchase a bag of coco coir that contains the optimal combination of those three components. Good quality coir is always harvested and processed correctly.

Choose sellers who ethically reveal the backstage life of the coco coir. Individuals should buy coir from manufacturers who do not store it in conditions that allow pathogens to breed. It would prevent one from witnessing their beloved plants die suddenly and unexpectedly due to bacterial or parasitic attacks.

Before adding coir to a hydroponic system, it must be rinsed and washed to remove harmful salts. Finally, the manufacturer should adequately package and store it. As a result, one must select a supplier who is open about their entire process, from production to shipping, and who has earned community trust for the products they sell.

How long does coco coir last?​

Coco coir fibers are cellulose with high lignin content. The component that gives coir its rigidity and woodiness is lignin. Decomposition of coco coir containing 45 to 50% lignin takes longer. In general, coco coir is highly durable and has a long lifespan. Its life, however, is also determined by its age and shape.

A good quality coconut coir will typically last four years before decomposing. Coconut husk that has been pre-composting will last for approximately four years without shrinkage or compaction, whereas husk that has not been composted will last for one and a half to two years.

If there is less fiber and more pulp in the coco coir, it will undoubtedly have a shorter life. Coarse coir will always outlast fine coir because the latter decomposes quickly due to its fine texture, whereas coarse fibers decompose slowly.

What are the benefits of coco coir?​

Ample drainage

Coco coir provides ideal drainage conditions for the plant, further reducing waterlogging. When the conditions are unfavorable for waterlogging, there are fewer chances of root rot. When farmers add coco coir to their hydroponic system, they can be relatively less anxious about overwatering or root rot.

Inexpensive

Coco coir is an affordable product and would not burn holes in one’s pockets. When compared to the prices of peat moss, the prices of coco coir are far more affordable, making it a reliable yet inexpensive growing medium.

Neutral pH

One of the most compelling and valuable advantages of using coco coir is its neutral pH, which does not negatively impact the plant’s living conditions. The competitor of coco coir- peat moss, is slightly acidic, making it a less suitable option when compared to coco coir. Thus, plants that cannot tolerate acidic conditions should always be paired with coco coir.

Healthy root growths

Coco coir is airy and gives the plant roots ample space to grow and occupy their own space. It allows the roots to get more air and oxygen, ultimately promoting their expansion.

Easy disposal

Unlike chemical additives, coco coir is an entirely natural product; therefore, one does not need to adhere to particular disposal guidelines. In addition, it also disintegrates very quickly, leaving no hazardous remnants.

Environment friendly

Coco coir is a renewable medium, making it more environmentally friendly than non-renewable peat moss. It is a waste product of coconut, and its usage contributes to the overall sustainability of the practice. Contrastingly, peat is derived from bogs, an exceedingly significant habitat for various organisms. The process of peat formation is tediously long, and its collection may threaten the native species living in the bog habitat.

Ease of transportation

Coco coir is magically easy to transport as it can be compressed and shipped in the form of bricks, taking up less space for a significant quantity. These bricks are generally lightweight and easy to maneuver for the manufacturer and farmers. Their lightness and ease of transportation mean that they can also be delivered online over long distances, increasing their availability even in remote areas.

Germ-free and recyclable

One can use coco coir without second thoughts as it’s free of pathogens, pests, or parasites. Moreover, coco coir is also recyclable. If used to grow saplings, one can reuse them for mulching the transplants.

High quantity of lignin

Lignin is the component responsible for providing rigidity and woodiness to the coconut fiber. The increased lignin level in coco coir makes it a fertile ground for good bacteria and protects against harmful pathogens. Its repulsion of pathogens makes coco coir a naturally ideal medium for most setups, including hydroponics.

High nutrient retention

Coco coir can retain more nutrients compared to other mediums. Moreover, it can also hold more moisture in large quantities and longer duration.

Conclusion​

The natural ability of coco coir to provide an ideal breeding ground for beneficial microorganisms, such as bacteria and fungi, is one of its most significant advantages.

Unfortunately, the coco coir you receive does not contain these microorganisms by default. These microorganisms must be introduced to your system via supplements or organic nutrients and fertilizers. To further promote the growth of microorganisms in your soil, try adding earthworm casting to the mixture.
