Seramis Clay Granules (200g)
Seramis is a fine clay granule which retains more water than any other clay substrate. It is capable of holding 100% of its own weight in water, therefore beating soil and coco too. Only the highest quality clay used in its production where a special clay extraction process and low temperature firing produces an incredibly porous surface. It’s very stable and completely inert, with a natural pH of 5.2 to 6.0 and a very low natural salt content Can be mixed into soil, coco or soilless mediums to improve drainage and increase humidity. Does not disintegrate - can be cleaned and re-used many times Ideal for leaf cutter setups and sub base in bio setups. Contains: 1 x 200g bag genuine Seramis Clay Granules
