For Hydroponics - Ensures good root aeration and prevents rotting, excess acidity and soil pests. It can replace horticultural soil, filter water quality, and maintain water and nutrients.
Produces negative ions and promotes plant growth
Can be reused after cleaning
11lbs per pack, Two pack total 22 Lbs., about 0.4 cm to1.5cm in diameter, mostly round and oval natural expanded clay.
Inert, pH-neutral, clean & decorative.
This natural clay is mined, formed into pellets, then kiln fired at high temperatures to cause the clay to expand into tough, lightweight balls. Clay naturally has balanced capillary action, with an ideal surface structure. The expanded clay is semi-porous and generally does not float like other products can. For best results, rinse all expanded clay before use. It is reusable as long as it is thoroughly cleaned between uses. Clean and clean, both beautiful and clean horticultural clay pebbles are made from 100% natural clay. They are clean, pH stable, and offer great aeration and drainage in hydroponics, especially in flood and drain, deep water culture, and drip feed systems. Due to their unique structure and ability to cover a large surface area, they offer the ideal environment to foster beneficial bacterial growth around the root zone, leading to naturally healthier plants.
Clay Pebbles benefits: Extremely stable in both pH and EC Made from 100% natural clay Strong structural integrity means that they are less likely to break and compact, which helps to prevent dripper systems from getting blocked
Pre-washed to aid in stability
Drains freely and does not hold any excess water, providing good oxygen levels around the root; suitable for flood and drain systems, multi-pot and drip feed systems
Pebble size 4mm - 16mm
Clay Pebbles can be used for: Aeration of growing media - ideal to mix into coco coir or soil to aid aeration
Drainage - will hold water as well as offering great aeration properties and free draining
