Fleximix Cubes |
These Fleximix plugs come in a specially designed tray and reservoir with a lid making them ready for use in any propagator.They are a 90% organic comprising of Peat and Bark elements bonded together with plant derived polymers. This material acts as a binding agent giving it a sponge like texture providing a perfect air to water ratio. They are pH stable and the medium will not compress like Rockwool cubes. They are also 100% bio degradable. These cubes have a double aperture to accommodate either seeds or cuttings. The first hole allows you to plant your seeds at the correct depth. The second hole is longer and thinner to take cuttings; this provides a nice snug fit which in turn help cuttings to root easier. |

Rockwool Growcubes |
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. |

| Rockwool Slabs | |
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. |

Clay Pebbles |
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. Comes in 50L bags. [Heavy Item] |

Perlite |
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. Comes in 100L bags. |

Vermiculite |
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. Comes in 100L bags. |

Worm Humus |
Plagron natural Worm Castings have a very high organic level and offer your crop an abundance of natural trace elements, enzymes, minerals, bacteria and fungi. Using worm castings has many advantages. It promotes faster and better germination of seeds, powerful root development, higher nutrient absorption in the plant and, ultimate, a better and higher yield. It also promotes general resistance. Plagron worm castings can be used at all times. It never burns, even with the most delicate plants. Plagron worm castings is not only highly fertile and natural, but is also economical and extremely user-friendly. Usage in full soil: You can fertilise 3 to 4 square metres with 1 litre of worm castings. Usage in potting soil: 10 to 20% worm castings: mix well. |

Vintage Bat Guano |
Bat Guano has long been known as a fantastic source of nutrition for soil-grown plants, offering a potent mixture of elements for enhanced plant health, root development and flowering. To use Bat Guano, you simply sprinkle it around the top of your pots and water it through - this obviously delays the immediate impact that you may expect from a flowering booster, but believe us when we say that the wait is worth it! The high organic phosphorous content of the Guano creates a huge increase in flower and fruit production both in terms of yield and quality and without having to resort to a mineral based booster. Highly recommended when growing in soil. |
