​PRO7 60/40 Clay Coco Premium Substrate | Ultimate High-Drainage & Biological Root Shield Medium

Take control of your plant cultivation with PRO7 60/40 Clay Coco—the premium-grade, highly aerated hybrid medium designed for maximum root performance. By blending 60% European Expanded Clay Pebbles (8–16mm) with 40% Pre-washed & Buffered Coco Coir, this mix delivers unparalleled root oxygenation, making it the ultimate defense against overwatering and root rot.

💡 The PRO7 Difference: The Pebble-Dominant Choice

PRO7 sticks to the classic, high-performance professional ratio of 60% Clay Pebbles and 40% Coco. This means PRO7 is highly aerated, drains incredibly fast, and is virtually impossible to overwater—making it the ultimate safety net for moisture-sensitive plants.

One Bag, Two Powerful Applications:

1. As a Standalone Semi-Hydro & Self-Watering Medium (Ready to Use)

The absolute gold standard for modern passive hydroponics, active reservoirs, and self-watering planters (such as Lechuza). The 40% premium coco coir acts like a high-performance wick, lifting moisture and liquid nutrients evenly up to the root zone, while the 60% clay pebbles create permanent, massive air pockets. Your plants get constant hydration without ever sitting in stagnant, oxygen-starved mud.

2. As a Premium "Chunky Mix" Soil Upgrade (The Ultimate Amendment)

Don't want to grow hydroponically? Use this bag as a premium structural additive to supercharge your standard peat or compost potting soils. Mixing this professional blend into ordinary houseplant soil instantly mimics an open, chunky forest-floor environment.

Why it beats Perlite & Bark: Unlike perlite, these clay pebbles will never float to the top of your pots, blow away, or turn an ugly yellow. Unlike orchid bark, they will never rot, decay, or compact over time. You get permanent, lifetime aeration.

How to Mix: Blend PRO7 60/40 with your standard potting soil to instantly double the drainage, prevent soil compaction, and keep root rot at bay.

Note: Because this amendment is naturally inert, it will slightly dilute your compost's built-in nutrients. We recommend starting your liquid feeding regime slightly earlier than usual to keep your plants thriving.

Perfect For High-Value Collectors & Moisture-Sensitive Species:

Whether used raw in a self-watering pot or mixed into standard compost, this clean, pathogen-free blend is the ultimate insurance policy for sensitive, rot-prone tropicals:

Rare Alocasias & Jewel Alocasias: (Black Velvet, Frydek, Jacklyn, and Polly — absolutely explode in semi-hydro setups where moisture is constant but oxygen is high)

Anthuriums & Velvet-Leaf Philodendrons: (Warocqueanum, Regale, and Melanochrysum thrive when roots can cling to coarse clay pebbles and airy coco fibers)

Monsteras: (Albo, Thai Constellation, and Esqueleto benefit from the massive, uncollapsible aeration that keeps their chunky roots healthy)

Hoyas & Peperomias: (Highly sensitive to waterlogging; benefits massively from the rapid dry-out cycle of the Hydrocorn pebbles)

Orchids & Epiphytic Plants: (Mimics the airy, bark-like tree environments they naturally grow in)

Perfect For High-Value Collectors & Hydro-Systems:

This clean, sterile, and pathogen-free medium is ideal for plants that demand pristine drainage and high root-zone oxygen:

Hoyas, Orchids, & Epiphytic Plants: (Thrive when roots can freely loop, breathe, and cling to coarse clay pebbles)

Rare Alocasias & Anthuriums: (Perfect for passive hydroponics and self-watering pots where stagnant moisture must be avoided)

Active Hydroponic Systems: (The absolute gold standard for Flood & Drain, Drip Irrigation, and automated pot systems)

Key Features & Cultivation Benefits:

Built-In Biological Root Shield (Trichoderma): This clean, professional mix naturally encourages beneficial Trichoderma fungi. These friendly microbes colonize your plant's root system, actively shielding them from harmful root-rotting pathogens (like Pythium) while supercharging nutrient uptake.

Permanent, Uncollapsible Structure: Unlike perlite or bark, expanded clay pebbles never break down, float to the top, or rot. The aeration you get on day one is the exact same aeration you have years down the line.

Ready to Use: Professionally pre-washed and buffered to ensure stable pH and EC levels from day one.

Boutique Sizes to Commercial Volumes: Carefully hand-decanted into convenient smaller volumes (1L, 5L, 10L, 15L, 20L) perfect for prized indoor collections, right up to our bulk 50L trade sacks.

How to Use & FAQs:

Saturate Before Use: Always thoroughly wet the substrate with a weak nutrient solution before potting up to ensure the coco fibers are fully primed.
