Atami Coco Substrate 50L – Premium Buffered Coconut Fiber for Explosive Roots

Atami Coco Substrate 50L is the high-performance growing medium you need to unlock the true potential of your genetics, offering the perfect balance between aeration and water retention to trigger explosive root growth and hydroponic-level yields. Unlike standard soil, this premium coconut fiber comes washed, buffered, and lightly fertilized, providing a clean, airy structure that allows your plants to eat more, grow faster, and produce heavier, denser flowers from day one.

Why your plants are begging for this change

Problem: Are you still struggling with heavy, compacted soils that suffocate your roots and slow down your crop's metabolism? Growing in traditional dirt often leads to inconsistent drainage, slower growth rates, and the constant fear of overwatering, which can turn a promising harvest into a nightmare of root rot and nutrient lockout.

Agitation: There is nothing more frustrating than seeing your plants stall because their feet are wet and they can't breathe. Every day your plants spend fighting through mud is a day of lost growth. This inefficiency doesn't just waste your time and electricity; it directly impacts the final weight of your harvest. You put in the work, but the medium is holding you back.

Solution: The Atami Coco Substrate is the game-changer that solves these issues instantly. Its structure guarantees a 20% air content even when wet, ensuring your roots always have access to oxygen. This means faster metabolic rates, zero risk of suffocation if watered correctly, and a root system that fills the pot in record time.

Before starting your grow

Switching to coco coir requires a slight shift in mindset compared to soil. Since this substrate is inert regarding NPK but buffered with calcium, you are the captain of the ship regarding nutrition. You don't need to wash this bag; Atami has done the dirty work for you, ensuring an EC of 1.75 thanks to the added calcium nitrate and limestone.

• Check your water: Ensure you have a pH and EC meter ready; precision is key in coco.
• Select the right food: You must use specific hydroponic nutrients or coco-specific fertilizers (A+B formulas are best).
• Don't compress it: When filling your pots, leave the coco fluffy. Do not press it down like soil, or you lose the aeration benefit.
• Plan your irrigation: Coco dries faster than soil, so be ready to water more frequently.

During cultivation: The explosive phase

Once your plants are settled, you will notice they drink much faster. This is a good sign! The high porosity of Atami Coco allows for aggressive feeding schedules. The trick to maximizing this substrate is the "wet-dry" cycle, although you should never let it dry out completely like peat. The sweet spot is keeping it consistently moist but not soaking.

Since this medium drains exceptionally well, it is the perfect candidate for automated drip irrigation systems. This ensures your plants get small, frequent doses of nutrients, mimicking a full hydro setup. Remember the golden rule of coco: always aim for 10-20% run-off (drainage) every time you water. This flushes out old salts and keeps the root zone fresh and chemically balanced.

After: Results and maintenance

When you chop down your plants, you'll likely find a root ball that is white, fuzzy, and has taken over the entire container. That is the Atami difference. The yield increase compared to soil is often significant due to the speed of vegetative growth and the ability to push harder during flowering.

Can you reuse it? Yes, but with care. You need to remove the old roots (using enzymes helps break them down) and likely re-buffer it if you washed it heavily. However, for the low cost of a fresh 50L bag, most professional growers prefer to start fresh to guarantee a pathogen-free environment for the next cycle.

Frequently Asked Questions

Do I need to wash this coco before use?

No, Atami Coco Substrate comes washed and buffered. The EC of 1.75 indicates it has been treated with calcium to ensure stability, so it's ready to use straight out of the bag.

How often should I water in coco?

It depends on the pot size and plant stage, but generally, you water more often than soil. Once a day or every two days is common. If you use cannabis fertilizers specifically for coco, follow their schedule closely.

Can I mix this with soil?

Absolutely. Mixing Atami Coco with soil (up to 30-50%) is a great way to fluff up the soil, improve drainage, and increase oxygenation if you aren't ready to go full hydro.

What is the pH of this substrate?

The pH is stable around 6.0, which is the sweet spot for nutrient uptake in cannabis plants grown in soilless mediums.

Personal Experience of Pevgrow’s CEO (Alan)

"I've always said that coco is the bridge between soil and hydro. When I use Atami's 50L bag, I treat it like a high-performance engine. I don't hand water if I can avoid it; I set up a simple dripper system. The key with this specific bag is that it's already buffered, which saves me the headache of soaking it in CalMag for 24 hours before starting. My tip? Don't let the EC scare you. That 1.75 is mostly the calcium buffer. Start your feeding with a mild vegetative dose, and you'll see roots popping out of the bottom of the pot in days. It's clean, it's consistent, and frankly, it's hard to go back to heavy soil after seeing the speed of this stuff."
