What: "From Husk to Gold: The Story of Coco Coir"
What is coco coir?
Coco coir is a 100% natural growing medium made from the fibrous husk of coconuts, and it is the leading peat-free alternative to traditional potting soil.
It is OMRI-certified organic, pH-neutral (5.8–6.8), and completely free of synthetic chemicals. Coco coir can hold up to 9× its weight in water while simultaneously maintaining 22–25% air porosity — a balance that peat moss and most soils cannot match. TrueCoirs coco coir is triple-washed to remove excess sodium and potassium salts, delivering a washed EC of 0.3–0.9 ms/cm — low enough for sensitive seedlings and heavy-feeding crops alike.
Good to know: Coco coir is suitable for soil gardening, hydroponics, container growing, seed starting, and worm farming — all from the same product.
What is coir pith — and is it the same as coco peat?
Coir pith (also called coco peat, coco soil, or coconut peat) is the fine, spongy material extracted from between the coconut husk fibers — and yes, all these terms refer to the same material.
It resembles fine brown crumbles or tea leaves and is the primary component in compressed coco coir bricks and blocks. Coir pith must be aged at least four months after processing to stabilize its structure and break down tannins that could otherwise interfere with plant nutrition.
Coir pith vs coir fiber: Pith holds more water but provides less aeration. Long-strand coir fiber holds less water but improves airflow and drainage. Most coco coir bricks contain a blend of both.
What is the pH of coco coir?
TrueCoirs coco coir has a pH of 5.8–6.8, which is near-neutral and within the optimal nutrient uptake range for the vast majority of plants.
You do not need to adjust the pH of the coir itself. However, always pH-adjust your nutrient solution to 5.5–6.5 before watering coco coir grows. If your runoff pH deviates more than 0.5 points from your input pH, it may indicate residual salts — flush with fresh pH-adjusted water until they stabilize.
TrueCoirs product specs: pH 5.8–6.8 | EC (washed) 0.3–0.9 ms/cm | Moisture 10–15%.
What is buffered coco coir — and why does it matter?
Buffered coco coir is coco coir that has been pre-treated with a calcium-magnesium (Cal-Mag) solution to saturate its cation exchange sites before you plant into it.
Raw coconut husks grow in coastal environments and are naturally high in sodium and potassium. When you hydrate raw (unbuffered) coir and add nutrients, the coir's cation exchange sites aggressively bind calcium and magnesium from your solution — starving plants of those elements even when you're feeding them correctly. This is the cause of roughly 40% of 'unexplained' deficiencies in coco coir grows.
Buffered vs unbuffered: Unbuffered coir steals Ca and Mg from your nutrient solution → deficiencies within 2 weeks. Buffered coir has exchange sites already saturated → nutrients go to your plant, not the medium.
TrueCoirs products are triple-washed to remove excess sodium and chlorine (EC 0.3–0.9 ms/cm), which is the essential first step. For cannabis and other heavy-feeding crops, complete the buffering by soaking hydrated coir in a Cal-Mag solution before first use.
Can coco coir be mixed with other growing media?
Absolutely! Coco coir can be mixed with other growing media such as soil, perlite, or vermiculite to create a customized blend for your plants.
What is coco coir made of, and how is it produced?
Coco coir is made from the fibrous husks of coconuts — a byproduct of the coconut food industry that would otherwise go to waste.
The production process:
Husks are retted (soaked in water for several months) to loosen the fibers.
Mechanical processing separates long coir fibers from fine coir pith.
The pith is washed — TrueCoirs triple-washes to remove sodium, potassium, and chlorine.
The washed pith is dried to 10–15% moisture content to prevent fungal growth.
Dried pith is mechanically compressed into bricks or blocks at a 5:1 ratio for efficient shipping.
Because coco coir uses a waste byproduct and requires no mining or bog destruction, it is the most environmentally responsible growing medium commercially available today.
How To Use: "Green Thumbs Made Easy: Harnessing the Potential of Coco Coir"
How do I use coco coir in gardening?
Simply rehydrate the coco coir by adding water, fluff it up, and use it as a growing medium for your plants in pots, containers, or raised beds.
Can coco coir be used as a standalone growing medium?
Yes, coco coir can be used alone or in combination with other additives, depending on the specific needs of your plants.
How often should I water plants when using coco coir?
Coco coir retains moisture well but also provides good drainage. Water your plants when the top layer of coco coir feels slightly dry to the touch.
Can coco coir be reused?
Yes, coco coir can be reused for multiple growing cycles. Simply refresh it by rinsing with water and removing any plant debris before reusing.
What nutrients does coco coir contain?
Coco coir is essentially inert — it contains no meaningful levels of nitrogen, phosphorus, or potassium, and must be supplemented with a complete fertilizer program from the very first watering.
This inertness is intentional and is actually one of coco coir's greatest advantages: it gives you complete control over what your plants receive. Unwashed coir does contain excess sodium and potassium from the coconut's coastal growing environment, which is why triple-washing (as with TrueCoirs) is critical.
Start feeding immediately. Unlike soil, coco coir has no nutrient reserve. Use a complete hydroponic or coco-specific fertilizer from week one at EC 0.6–1.0 for seedlings.
How much does a 10 lb block of coco coir expand?
A 10 lb (5 kg) TrueCoirs coco coir block expands to 70–75 liters — roughly 18–20 US gallons — when fully hydrated with water.
The 5:1 compression ratio means every block contains 5× the usable volume it appears to hold. Add water slowly and allow 30–60 minutes for full expansion.
How do I hydrate or rehydrate coco coir bricks and blocks?
To hydrate a coco coir block, place it in a large container, add water slowly until fully saturated, then wait 30–60 minutes and break apart by hand to remove dry pockets.
Step-by-step for a 10 lb block:
Place the compressed block in a container at least 25 gallons in capacity.
Slowly pour 4–5 gallons of water over the block — do not dump it all at once.
Wait 30–60 minutes for full absorption.
Break the block apart with your hands or a garden fork, working from the outside inward to release dry pockets.
Check the center — if still dry, add another quart of water and wait 10 minutes.
Drain any excess standing water and the coir is ready to use.
To rehydrate used coco coir from a previous grow: rinse with fresh water, remove all plant debris and root matter, then repeat the steps above. For plants sensitive to pathogens, soak in a 3% hydrogen peroxide solution for 30 minutes before re-buffering.
