Jiffy PRO7 LECA Clay & Coco Semi-Hydro Mix 60/40

⚪ Type: Unfertilised / Blank Canvas
No nutrients have been added at all. This gives you total control over feeding from day one, with zero risk of the substrate fighting your own nutrient plan. The tradeoff: you must start feeding immediately — there's no built-in safety net if you forget or under-feed early on.

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 — a 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 an excellent defense against overwatering and root rot.

One Bag, Two Powerful Applications:

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

The gold standard for passive hydroponics, active reservoirs, and self-watering planters. The 40% premium coco coir acts like a wick, lifting moisture and liquid nutrients evenly up to the root zone, while the 60% clay pebbles create permanent, massive air pockets — constant hydration without stagnant, oxygen-starved mud.

2. As a Premium "Chunky Mix" Soil Upgrade

Use this bag as a structural additive to supercharge your standard peat or compost potting soils. Mixing this blend into ordinary houseplant soil instantly mimics an open, chunky forest-floor environment. Unlike perlite, these clay pebbles won't float to the top, blow away, or discolour. Unlike orchid bark, they won't rot, decay, or compact over time.

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

Perfect For Moisture-Sensitive Species:

• Rare Alocasias: Black Velvet, Frydek, Jacklyn, and Polly thrive 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 fibres.

• Monsteras: Albo, Thai Constellation, and Esqueleto benefit from the uncollapsible aeration that keeps chunky roots healthy.

• Hoyas & Peperomias: Highly sensitive to waterlogging; benefit massively from the rapid dry-out cycle.

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

Key Features & Cultivation Benefits:

• Built-In Biological Root Shield (Trichoderma): This mix naturally encourages beneficial Trichoderma fungi, which colonise your plant's root system and help shield against harmful root-rotting pathogens while supercharging nutrient uptake.

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

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

• Boutique Sizes to Commercial Volumes: Available from 1L up to bulk 50L trade sacks.

Technical Specifications:

• Blend: 60% Expanded Clay Pebbles (8–16mm) / 40% Coco Coir

• pH Level: 6.9 ± 0.5 (Buffered and stable)

• EC Value: 1.3 mS/cm

• Organic Matter: 14%

• Dry Matter: 61%

• Media Type: Sterile, inert hydroponic/soilless mix (requires liquid feeding)

How to Use:

Always thoroughly saturate the substrate with a weak nutrient solution before potting up to ensure the coco fibres are fully primed. Because this is an inert, professional medium, it contains no built-in fertilisers — we recommend a high-quality hydro-specific nutrient range such as VitaLink Hydro MAX to feed your plants from day one.
