Canna Aqua Clay Pebbles
This 20 or 45 litre bag of clay pebbles comes from the makers of one of the most popular nutrient lines out there. Ideal for use in most hydroponic systems - IWS, Wilma, Aquafarm, etc., and also great for improving drainage and aeration in more traditional mediums like soil and coco.
Used in an array of hydroponic systems, clay pebbles have a rough porous texture and are capable of holding onto quite a lot of water. At the same time, because of the air gaps in the substrate, drainage is almost free flowing, which is why it's such a popular choice for recirculating systems, helping to reduce issues caused by water logging. These gaps also help to oxygenate the rootzone, which in turn generates huge gains in terms of plant growth and development.
