Colossal Expanded Clay 8 mm – 16 mm 50 L Bag – Premium LECA for Vigorous Growth
Give your plants the ideal balance of moisture, oxygen and support with Colossal Expanded Clay. Sourced from high-quality natural clay and kiln-fired into 8 mm – 16 mm pebbles, this inert, pH-stable media delivers consistent performance across hydroponic, aquaponic and soil-based systems.
Consistent Particle Size: Uniform 8 mm – 16 mm pebbles prevent blockages, simplify dosing and ensure even root penetration.
Superior Porosity (70 % – 80 %): The micro-porous structure soaks up water and nutrients, then releases them directly at the root zone as needed.
Exceptional Aeration & Drainage: Non-compacting ceramic shell creates air pockets around roots, preventing waterlogging and reducing root-rot risk.
Inert & Low Electrical Conductivity: Completely mineral and free from fibres or solvents, Colossal Expanded Clay won’t alter pH or raise EC in your nutrient solution.
Lightweight, Durable & Reusable: Easy to rinse, clean and reuse indefinitely—this eco-friendly media offers long-term value for any grower
