Stonewool Cube Slab

Stonewool is a nice clean media which has a perfect air:water ratio and comes in a ready to use cube format.

Stonewool is a natural media made from a volcanic rock (basalt).  The rock is liquefied under extreme heat in special furnaces and then spun into threads and re-solidified into cube format. The production process guarantees sterility in the final product.

When hydrated, each cube has a consistent 80% Water 20% Air ratio which makes it an ideal media for hydroponics as it is difficult to over water the cubes. This prevents seedling problems such as damping off.

To use this media simply unpack it from the box, fully saturate the cubes and then drain them off, place the cubes onto your propagating table, place the seed in the pre-punched hole provided on top of the cube, shower the cubes with water to wet the seeds and leave to germinate, watering when required. Once the seedlings reach a reasonable size for transplanting simply separate the cubes, place in cups with media mix and plant into your growing system.

1 Stonewool slab = 100 cubes, enough for x2 growing seasons
