Coco Fiber Brick 5 Kg (80L) – The Ultimate Fluffy Substrate for Explosive Roots

The Coco Fiber Brick 5 Kg (80 Liters) is not just a block of dried husk; it is the blank canvas for your best harvest yet. This compressed substrate offers the perfect balance of water retention and oxygenation, allowing you to turn a compact, lightweight package into a massive volume of high-performance growing medium in minutes. It is the smartest choice for growers who want professional results without the hassle of hauling heavy bags of soil.

Are you tired of hauling heavy bags and dealing with suffocated roots?

Let’s be real: carrying 50-liter bags of soil up the stairs is a workout nobody asked for, and it’s not exactly discreet. But the real problem isn't just the weight; it's what happens inside the pot. Traditional soils often compact over time, choking your plants' roots, preventing them from breathing, and creating a breeding ground for fungi and pests that can ruin months of hard work.

There is nothing worse than seeing your plants droop because of root rot or slow growth due to a lack of oxygen. You spend money on expensive nutrients, but if the roots can't absorb them because they are drowning in mud, you are literally flushing your budget down the drain. It’s the classic "here we go again" frustration that makes you want to quit.

The Coco Fiber Brick is the solution that changes everything. It weighs only 5 kg but expands to 80 liters of fluffy, airy gold. This structure ensures that your roots always have access to oxygen, even right after watering. It’s impossible to over-compact it, meaning your plants will eat more, grow faster, and yield heavier flowers. Plus, you can carry it in a backpack without anyone knowing.

Why this product is actually worth it for you

If you are looking for efficiency, this brick is unbeatable. The quality-to-price ratio is insane when you consider the volume you get. Unlike pre-mixed soils that come with their own nutrient load (which might not match your plant's current stage), coco fiber is inert. This gives you total control. You decide exactly what your plants eat from day one, treating them like the high-performance athletes they are.

It is also the ultimate "forgiving" medium. Because it drains so well, it is very hard to overwater your plants compared to soil. Whether you are a beginner afraid of drowning your seedlings or an expert running a high-frequency fertigation setup, this substrate adapts to your style. It’s clean, sustainable, and reusable if treated correctly.

Most important features and benefits

• High Porosity: It holds plenty of water while maintaining excellent air pockets. This means faster root development and more vigorous vegetative growth.
• Compressed Format: A 5 kg brick turns into 80 liters. This means easy transport and storage—perfect for stealth growers or those with limited space.
• Inert Medium: It contains no nutrients. This allows you to customize the feeding schedule perfectly using cannabis fertilizers without risk of nutrient burn from the soil itself.
• Pathogen Free: Being a sterile medium, you start with a clean slate, reducing the risk of pests and soil-borne diseases significantly.
• Eco-Friendly: Made from coconut husks (a waste product of the food industry), it is a sustainable choice that doesn't deplete peat bogs.

Typical objections and clear answers

We know switching substrates can be scary, but let's clear up the common doubts:

• You think that hydrating it is a messy hassle. In reality, you just throw it in a large tub with water, wait a few minutes, and fluff it up. It’s actually satisfying to watch.
• You think that coco dries out too fast. In reality, it holds moisture incredibly well, but because it breathes so well, you can water more often (feeding the plant more) without suffocating it.
• You think that it lacks nutrients. In reality, this is a huge advantage. You aren't stuck with the NPK ratio of the soil manufacturer; you are the chef creating the perfect diet.

How to use it safely and effectively

To get the monster yields this substrate is capable of, follow these simple steps:

1. Hydration: Place the brick in a large container (remember, it expands to 80L!). Add about 20-25 liters of water. Warm water speeds up the process.
2. Buffering (Crucial): Coco tends to hold onto Calcium and Magnesium. To prevent deficiencies, add a dose of CalMag Pro by Plagron to the hydration water.
3. Fluffing: Once it has absorbed the water, break it up with your hands until it's light and airy.
4. Mixing (Optional): You can use it pure for hydroponics or mix it with perlite or worm castings if you want to create a super-soil.
5. Planting: Fill your Indoor and Outdoor Planters. Do not press it down too hard; let gravity settle it to keep the oxygen pockets.
6. pH Control: When watering in coco, aim for a pH between 5.8 and 6.2 for optimal nutrient uptake.

Frequently Asked Questions

Can I reuse the coconut fiber?

Yes, you can! Unlike peat, coco degrades very slowly. You can reuse it for 2-3 cycles if you use enzymes to break down old roots and flush it well to remove salt buildup.

Is this suitable for automatic watering systems?

Absolutely. In fact, it's one of the best mediums for Hydroponic and Aeroponic Systems because it doesn't clog drippers as easily as soil and drains perfectly.

Do I need special nutrients for coco?

While you can use universal nutrients, it is highly recommended to use a line specifically designed for Coco or Hydro, or at least supplement with CalMag regularly to keep the plants happy.

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I first switched from soil to coco bricks. I was skeptical about the "extra work" of hydrating the brick. But the moment I saw the root mass on my first harvest, I never looked back. The white, fuzzy, healthy roots were filling the entire pot, something I rarely achieved with heavy, compacted soil.

My advice? Don't skip the buffering step. If you hydrate it with CalMag water from the start, you avoid 90% of the yellowing issues people complain about. It’s the cleanest, most controllable way to grow if you want to push your genetics to their limit. Plus, storing a stack of these bricks in the closet takes up zero space compared to bags of soil.
