Ideal for all types of hydroponic growing, these products offer you ideal air/water balance, simple controllability of water and nutrients and strong root growth throughout the entire block. Grodan rockwool blocks can support small to medium sized plants from start to finish, but are most often used in combination with cubes and slabs for longer term crops such as tomatoes.

Growcubes are small, separate, equally sized cubes with dimensions of 1 x 1 x 1 cm. These have excellent water-retentive properties with a shape and solidity that ensure that there is a high percentage of air in the container. The ideal air/water ratio provides the foundation for the efficient control of the crop throughout the production cycle.  These characteristics result in large pores between the cubes that ensure a minimum air content of 30%, guaranteeing sufficient availability of air for healthy, active roots – even at higher water contents.

Available in 20 or 90L.

These slabs come in clearly marked UV resistant poly sleeves for ease of use. Recommended for larger, long term crops with extensive roots like peppers, tomatoes, or cucumbers. Typically, seedlings in blocks are placed onto slabs. Grodan Expert is the slab that drains the fastest because of its vertical fibers. By far the most popular slab for the hydroponic hobbyist market.

Growing in B’cuzz coco means growing in 100% natural soil made from coco dust and fibres. B’cuzz coco substrate is washed and buffered. The coco medium has good retention and direction qualities for water with nutrients so that an optimal absorption of the liquid nutrients may be realised. The B’cuzz coco is lightly fertilised.

Comes in 50L bags.

Clay pebbles are a popular hydroponic medium around the world. Manufactured in Germany. They are used both for commercial production and for decorative purposes such as a top layer for pot plants. Hydroton pebbles are light in weight, do not compact and are completely reusable - they can be cleaned and sterilised after use. They are also inert, pH neutral and contain no nutrients. Because the pellets drain freely and don't hold excessive water, they provide good oxygen levels around the root zone and are particularly suitable for flood and drain systems. In drip irrigation, the pellets can be mixed with a medium with better capillary action, so the feed is dissipated broadly through, to prevent salt build-up.

Perlite is produced from a volcanic alumino-silicate rock, which is first crushed and then heated to a temperature slightly below 1000°C. At this temperature the water and gas (which is trapped) vaporises to expand the particles rather like popcorn, producing very light aerated white mineral foam.

The rough external surface of the granules is mainly responsible for the considerable capillary attraction which perlite has for water. This makes perlite ideal for wick or pot systems provided a reservoir of nutrient solution is maintained at all times. Great for aerating soil mixtures.

Vermiculite, like perlite is an alumino-silicate material. Vermiculite has a high cation exchange capacity. This means that even after over-watering (which will cause many mediums to lose nearly all their nutrient content) vermiculite will, when drained, hold onto some nutrient that will be released back into solution with the next watering. It is normally added at between 5-50% by volume.

The other use of vermiculite is as a seed covering. This practice utilises the material’s extreme light weight and its capacity for providing a high humidity around the seed. At the same time it is not so dense as to cut out all light to the seeds.
