CANNA COGr Slab – Premium Compressed Coco Substrate for Faster Roots & Bigger Yields

The CANNA COGr Slab is the ultimate compressed coco substrate, engineered to transform your grow space from chaotic to controlled. This isn't just another bag of medium; it's a precision tool designed for growers who value efficiency, cleanliness, and maximizing every harvest.

Ever feel like your grow room is a constant battle against loose coco fibers, uneven watering, and messy runoff? You're not alone. That scattered, unpredictable environment steals your time and stresses your plants, leading to inconsistent growth and subpar yields. It's frustrating when you know your genetics are fire, but your setup is holding them back. The CANNA COGr Slab solves this by providing a uniform, stable foundation. Its compressed form expands into a perfectly balanced coco medium, giving you control and predictability from day one.

How Your Grow Space Transforms with the COGr Slab

Imagine opening your tent to a neat, contained grow bed instead of a sprawl of pots and spilled substrate. The COGr slab creates a defined, professional-looking area. Watering becomes precise, with even distribution and predictable runoff. No more dry pockets or waterlogged roots. The slab's structure promotes a massive, healthy root zone that spreads evenly, leading to uniform plant growth and a canopy that's a joy to train. Your grow space goes from a DIY project to a streamlined production zone.

What You Can Organise with This Product

The COGr Slab is the cornerstone of an organised hydroponic or drain-to-waste system. It's designed to bring order to:

• Your entire root zone: Provides a consistent, aerated home for roots to explode.
• Nutrient and water delivery: Its homogeneous structure ensures even feeding.
• Your grow schedule: Reuse it up to three times, cutting down on waste and prep time between cycles.
• Your budget: One slab replaces multiple bags of loose coco over several grows.
• Your environmental impact: It's a 100% natural, renewable, and reusable product.

Steps to Build Your Organised Coco Setup

Setting up with a COGr Slab is straightforward and sets the stage for a stress-free grow.

1. Prepare Your Space: Place the slab in your chosen tray or container. It measures 100x15x7.5 cm and expands.
2. Buffer and Expand: Hydrate the slab with a solution containing CANNA COGr Buffer Agent (sold separately) to prepare the coco and set the ideal starting pH.
3. Establish Drainage: Ensure your container has proper drainage. A layer of clay pebbles at the bottom can help.
4. Plant and Feed: Place your seedlings or clones directly into the slab. Begin feeding with the dedicated CANNA COGr nutrient line (Vega for growth, Flores for bloom).
5. Maintain and Reuse: After harvest, flush the slab with a double dose of CANNAZYM, let it soak, and it's ready for another round.

Advantages and Benefits of a Structured Coco Grow

Switching to a slab system isn't just about tidiness; it's about unlocking potential.

• Faster Root Development: The unique mix of coco flakes, fibers, and granules creates an ideal air/water ratio (73% water, 23% air) for explosive root growth.
• Higher Yields: A superior root zone directly translates to healthier plants and bigger harvests.
• Reusability: Use it for up to three cycles, making it an incredibly cost-effective and sustainable choice.
• Consistent Quality: As an RHP-certified product, you're guaranteed a substrate free of pests, diseases, and chemical additives.
• Easy Transport & Storage: The compressed slab weighs only 2kg, making it easy to handle and store compared to bulky bags of loose coco.
• Predictable Performance: Eliminates the variables of inconsistent, low-quality coco, giving you reliable results every time.

Frequently Asked Questions

How much expanded coco does one slab make?

One CANNA COGr Slab expands to provide between 21 to 25 liters of uncompressed, ready-to-use coco substrate.

Can I use it in regular pots?

Absolutely. Simply hydrate and break up the slab to fill your pots. It works perfectly in fabric pots or standard containers for a supercharged coco-perlite style mix.

Do I need to use CANNA nutrients with it?

While it's optimized for the CANNA COGr Vega and Flores lines, you can use other coco-specific nutrients. Just ensure you buffer the slab first with the CANNA COGr Buffer Agent for the best start.

How do I prepare it for reuse?

After harvest, remove plant debris, flush thoroughly with a strong CANNAZYM solution, and let it soak for 24 hours. No re-buffering is needed for subsequent uses.

Is it pre-fertilized?

No, the CANNA COGr Slab is not pre-fertilized. This gives you complete control over your nutrient regimen from the very beginning.

Personal Experience of Pevgrow’s CEO (Alan)

Let me be straight with you: I was a die-hard loose coco guy for years. The switch to the COGr slab felt like upgrading from a messy artist's studio to a surgeon's operating room. The first thing you notice is the lack of dust and debris – it's clean. Hydrating it with the buffer solution is simple, and watching it expand into this perfect, fluffy block is weirdly satisfying. In use, the consistency is what sold me. Every plant gets the same environment, which means no more guessing why one is lagging. The root systems I've pulled from these slabs are insane – thick, white, and everywhere. The reusability is a game-changer for my perpetual grow; I just clean, soak, and go again. My pro-tip? Pair it with a simple drip system on a timer. The slab's water retention and drainage are so balanced that it takes the guesswork out of watering, letting you focus on the fun parts of growing.
