"Zamnesia Coco Bricks give you a clean, stable growing medium with full control over moisture and nutrient delivery. Each brick is pre-washed and buffered, so you know exactly what your plants are getting from day one. Just drop one brick into a bucket with 4 to 5 litres of water, leave it for around 30 minutes, then break it apart to get roughly 10 litres of ready-to-use substrate. Simple, no mess.
The coco fibres are 100% organic and come with a pH of around 6.0, which keeps things stable without much fiddling. The light, airy structure supports strong root development and holds moisture well while still letting plenty of oxygen reach the roots. Use it as a straight coco grow medium or blend it into soil to improve drainage and conditioning. Each brick weighs 650 g and expands to approximately 10 litres. Store any unused bricks somewhere cool and dry, and keep hydrated coco out of direct sunlight."
