Why are more and more growers switching to coco?
It’s a real global trend that peat is disappearing as a cultivation option.
Since it has been banned in some countries, such as the UK, the agri-food industry has turned to finding effective substitutes as a growing medium.
One of these substitutes is coco fibre.
Imagine a substrate that breathes, drains well, but retains just the moisture your roots need to expand without stress. That’s coco coir.
What’s more, it’s an inert growing medium, meaning it contains no nutrients on its own.
That might sound like a downside at first, but for producers and cultivators it‘s a great advantage. You control what your plants absorb and when. This makes for quicker and more accurate responses, and fewer surprises during cultivation.
Top Benefits of Using in Coco Coir
✔️ Light and airy structure that boosts root oxygenation — stronger roots = stronger plants.
✔️ Absorbs and holds water without becoming waterlogged. Say goodbye to overwatering issues.
✔️ Reusable with proper maintenance, so you get more value per grow cycle.
✔️ More sustainable than peat — and with peat bans already active in the UK, coco is the go-to option for eco-conscious growers.
It’s all about structure: coco doesn’t compact, it doesn’t drown your roots, and it stays evenly moist. For all these reasons coco accelerates growth, improves nutrient uptake and helps prevent common problems such as root rot.
So, it’s no wonder coco has become a favourite — whether for newer cultivators or experienced ones.
But of course, not everything is automatic: to succeed with you’ll need proper care and fertilisers made specifically for coco substrates.
That’s where B’cuzz steps in.
How to Fertilise Coco for Best Results?
So, now you know coco coir is a top-tier substrate. But here’s the catch: coco is not soil.
And that means you can’t treat it like soil — especially when it comes to nutrients.
Coco fibre has a peculiarity: it is naturally rich in potassium, but poor in calcium. If you don’t balance that from the start, your plants will show deficiencies fast.
That’s why at Atami, we created a full line designed just for coco:
👉 B’cuzz Coco — nutrients tailored to unlock the full potential of this “new soil”.
What does each product in the B'cuzz Coco range contain?
Here is a table to help you understand at a glance how a complete and powerful coco growing table works:
| Product | What does it bring? | When to use it? |
| Coco A | Calcium (4% w/w), nitrogen and other basic elements | Throughout entire cycle. |
| Coco B | Phosphorus + essential micronutrients | Together with coco A, during the whole cultivation period |
| Coco Booster Uni | Plant extracts, magnesium and iron | In the transition between rooting and flowering, to alleviate stress and strengthen growth |
| Coco Bloom Stimulator | Bloom stimulator with plant extracts | From the beginning of flowering, to activate the first buds |
Together, these four cover your entire coco grow cycle, from seedling to harvest. But there’s more…
When your plants start packing on weight during late flowering, it’s time to bring in the heavy hitters:
Bloombastic and Rokzbastic — two bloom additives that level up your results in coco coir.
• Bloombastic is a flowering booster with a balanced phosphorus and potassium ratio, with biostimulants and iron, ideal to stimulate, enhance flowering and natural aromas and flavours.
• Rokzbastic has twice as much potassium as phosphorus for rokz-solid ripening results, compact and tasty flowers.
The result? Denser, heavier and tastier fruit. Just what you were looking for.
Which coco substrate to use with B'cuzz? The difference is in your style
You already know that growing in coco has many advantages. And you also know that not just any fertiliser will do — you need a tailored feed like B’cuzz Coco.
But there is something else that makes the difference between an average crop and a great one: the quality of the coco substrate you choose.
A poorly processed coco coir can ruin your crop. At Atami, we don’t take chances.
We control the entire process — from raw material selection to final packaging — to guarantee you clean, stable, grow-ready coco.
What makes our coco substrates special?
👉 We select the best raw material: we only work with premium quality coco, free of residues and with an optimal texture for cultivation.
👉 Correctly Aged– we age the material to break down any remaining organic matter.
👉 Washing – to flush out salts and residues that may affect the electrical conductivity (EC) of the substrate.
👉 Perfect buffering: we adjust the pH and balance the calcium and magnesium levels, which prevents the coco from “stealing” nutrients from the plant.
The result? A clean, stable and balanced substrate. Ideal for using it directly with the B’cuzz Coco range, with no surprises or nutrient blockages.
What are our coco substrates?
• Cocos Substrate: a professional, ready-to-use coco with high water holding capacity and excellent drainage. It has a medium fertilisation.
• High Porosity Cocos: with added perlite to further improve aeration and prevent compaction. It has a medium fertilisation.
• Washed & Buffered Cocos: is the same as Coco Susbtrate but with a big difference: no pre-fertilisation. It is an ideal blank canvas for experienced growers who want to start their nutrition from scratch, and for cuttings and sprouts.
• Coco Slabs: perfect for drip systems, run-to-waste setups or in-line cultivation. Same high standard in a hydroponic-friendly format.
Calcium & Magnesium: The Essential of Coco Cultivation
One of the key secrets to make the most out your coco growing is understanding how this medium interacts with nutrients.
Coco coir naturally comes packed with potassium – great, right? Well, yes… but it also tends to hang on to calcium and magnesium, which can stop your plants from taking them up properly if you’re not careful.
So, what does that mean in real terms?
Even with a good nutrient line, you could be setting your plants up for deficiencies if you’re not adding a calcium and magnesium supplement.
At Atami, we know this all too well. That’s why Coco A is enriched with extra calcium (4% w/w) – ideal for working in perfect balance with our pre-buffered coco coir substrates.
Still, if you’re growing heavy feeders or using soft water (low in minerals), topping up with extra CalMag can be a game-changer, especially in the early veg stage when demand is higher.
Keep an eye out for early signs of deficiency – yellow leaf edges, twisted new growth, or sluggish development. Spot any of these? Bring in ATA CalMag. Your plants will bounce back – and it’ll show you in the production.
💡 Pro tip:
If you want to continue applying a CalMag supplement during flowering, but without adding extra nitrogen, then VGN CALMAG is your ally! This organic supplement is nitrogen-free.
Tips for getting the most out of your coco crop
Before you start growing in coco with the B’cuzz range, here are some key tips to make your experience a success:
• Start with quality coco
It seems obvious, but not all cocos are the same. Make sure it is well washed, buffered and balanced, like Atami coco coir. Cheap or poorly processed coco can do more harm than good (hello, nutrient lockout 👋).
• Water carefully
The coco drains well, but it also retains water. Water frequently, but don’t overdo it. It is better to water several times a day in small doses rather than once a day.
• Control pH and EC
Balance is everything in coco. Use meters to adjust your nutrient solution to between 5.5 and 6.2 pH, and keep the EC within the appropriate range depending on the phase (vegetative or flowering).
• Use coco-specific fertilisers
Coco has unique needs – don’t try to wing it with generic fertilisers. Use products designed for coco, like B’cuzz Coco A&B, Coco Booster Uni and Coco Bloom Stimulator. And don’t forget your CalMag! If your plants ask for it, ATA CalMag or VGN CALMAG delivers.
• Reuse wisely
Good news: you can reuse coco 2 or even 3 times. Just make sure to flush it thoroughly between runs and re-buffer it before starting fresh. A clean start = happy roots.
Growing in coco is easy – when you know what you’re doing.
With Atami’s coco substrates and nutrients, you’ve got everything you need to level up your cultivation. Clean, efficient, productive.
