Plagron Hydro Coco 60/40. 

Most growing media force you to compromise.

You either get moisture retention and terrible airflow…

…or fantastic drainage with all the water-holding capability of a kitchen sieve.

And this is where Plagron Hydro Coco 60/40 barges into the hydroponics world wearing steel-toecap boots and carrying the confidence of a Dutch engineer who’s just redesigned gravity.

Because this stuff is not ordinary substrate.

It’s a beautifully balanced fusion of oxygen-rich expanded clay pebbles and premium buffered coco fibre designed specifically for growers who understand that massive plants begin with absurdly healthy roots.

And frankly, it’s brilliant.

Plagron has essentially taken two of the best hydroponics substrates available, forced them into the same bag, and somehow created a growing medium that behaves like both while suffering from the weaknesses of neither.

Which is annoyingly clever.

The Magical 60/40 Formula. 

At the heart of Plagron Hydro Coco 60/40 is a deceptively simple recipe.

60% expanded clay pebbles. 40% premium buffered coconut fibre. That’s it.

But much like a V8 engine or a proper Yorkshire pudding, simplicity often hides genius.

The expanded clay pebbles provide exceptional oxygen retention and drainage, while the coco fibre delivers moisture stability, nutrient buffering and root support.

Together they create a hydroponics substrate with an almost perfect balance of water and air.

And plants absolutely adore it.

Because roots are strange little biological creatures.

They want moisture.

But not too much.

They want oxygen.

But not dryness.

They want stability.

But also rapid nutrient movement.

Honestly, roots are basically impossible to please.

Plagron Hydro Coco 60/40 somehow manages it anyway.

Roots with Breathing Room. 

One of the biggest problems in growing is lack of oxygen around the rootzone.

People obsess over nutrients, lighting and additives with names that sound like illegal energy drinks, yet completely ignore the fact that roots need oxygen to function properly.

Without airflow, nutrient uptake slows dramatically.

Growth stalls.

Roots become stressed.

And eventually the whole thing starts smelling like regret and wet socks.

Plagron Hydro Coco 60/40 solves this beautifully.

The 60% clay pebble ratio creates massive air pockets throughout the substrate, allowing oxygen to circulate freely around the rhizosphere.

Which is the scientific term for “the bit underground where all the important wizardry happens.”

This increased oxygen availability leads to:

Faster root development
More aggressive nutrient uptake
Improved metabolic activity
Reduced risk of root disease
Explosive vegetative growth
Enhanced flowering performance

In hydroponics systems, oxygen is everything.

And this substrate delivers it in industrial quantities.

Drainage That Would Impress Your Plumber.

Now then. Drainage.

Because hydroponics growers eventually discover one universal truth.

Overwatering is astonishingly easy.

Particularly in dense coco or heavy soil mixes where water sits around the roots like a stagnant swamp waiting for disaster.

Plagron Hydro Coco 60/40 fixes this by allowing water to move rapidly through the substrate while still retaining enough moisture for stable feeding conditions.

The expanded clay pebbles prevent compaction and create clear drainage pathways throughout the rootzone.

Excess nutrient solution drains quickly.

Fresh oxygen replaces it immediately.

Roots remain healthy, active and wonderfully aggressive.

This makes Hydro Coco 60/40 ideal for:

Run-to-waste hydroponics
Drip irrigation systems
Recirculating hydroponics systems
Flood and drain tables
Hand-watered pots
High-frequency fertigation setups
Large fruiting plants
Fast-growing indoor crops

It’s essentially a high-performance motorway for water and oxygen.

Properly Buffered Coco.

Cheap coco products are chaos.

One bag arrives perfect.

The next arrives filled with sodium, unstable EC levels and enough buffering issues to trigger a small horticultural breakdown.

Plagron avoids this nonsense entirely.

The coco inside Hydro Coco 60/40 undergoes multiple buffering and flushing stages before it ever reaches the bag.

This removes unwanted salts and stabilises the substrate properly before use.

Which means growers receive:

Low initial EC
Stable pH performance
Reliable nutrient uptake
Consistent feeding behaviour
Reduced nutrient lockout risk

The result is a hydroponics substrate that behaves predictably from day one.

And predictability, in indoor growing, is priceless.

Optimised for Aggressive Feeding Schedules.

One of the truly impressive things about Plagron Hydro Coco 60/40 is how well it handles intensive hydroponics feeding programs.

Because of the superb oxygen balance and rapid drainage characteristics, growers can feed more frequently without creating anaerobic root conditions.

Which plants absolutely love.

Particularly fast-growing flowering varieties that consume nutrients with the enthusiasm of a Labrador discovering an unattended roast chicken.

Pair Hydro Coco 60/40 with Plagron Cocos A & B nutrients and the whole system becomes frighteningly efficient.

Nutrient uptake accelerates.

Growth rates increase dramatically.

Root systems become enormous.

Plants start behaving like they’ve discovered performance-enhancing substances.

Lightweight. Airy. Surprisingly Civilised.

Despite the heavy-duty hydroponics performance, Plagron Hydro Coco 60/40 remains remarkably easy to work with.

The substrate feels airy and loose without becoming unstable.

The clay pebbles distribute evenly throughout the coco rather than separating awkwardly like cheap substrate mixes often do.

And because the structure remains physically stable over time, the rootzone continues receiving oxygen deep into flowering.

This is enormously important in hydroponics systems where compacted substrate can quietly suffocate roots during late-stage growth.

Hydro Coco 60/40 simply keeps breathing.

Even when your plants are consuming water like tiny botanical V8 engines.

Plagron. For Serious Growers. 

This isn’t supermarket compost for people growing sad basil on a kitchen windowsill.

Plagron Hydro Coco 60/40 is designed for growers chasing serious performance.

The kind of growers who monitor EC levels like stock traders.

The kind of growers who understand the importance of oxygen-rich rootzones.

The kind of growers who appreciate the beautiful simplicity of a substrate that just works properly every single time.

Whether you’re cultivating vegetables, ornamentals, tropical plants or high-performance indoor crops, Hydro Coco 60/40 creates an incredibly stable environment for rapid growth and heavy flowering.

And because the substrate can be reused, it also becomes remarkably economical over time.

Which is always nice considering hydroponics growers already spend enough money turning spare rooms into miniature climate-controlled ecosystems.

Dutch Hydroponic Mastery. 

What Plagron has created here is genuinely impressive.
