Growing Media

What is Hydroponics Growth Media.

Growth Media can be made of anything that holds a plants root structure. Remember growing cress in cotton wool at school. In Hydroponics, we use all sorts of different growth media for different growing applications.
When to use Hydroponic Growth Media in your Grow room.
Growth Media is used throughout a plants life cycle. from seedlings to cuttings and through adulthood – Plants need a growth media to establish their root structure.
Benefits of Hydroponic Growth Media in your Grow room.
Different growth medias have different benefits. Some growth media come with essential nutrients and minerals already in them, reducing the need for use of nutrients and nutrient additives. Other growth medias are completely inert, meaning they have no nutrient value, hence you add the nutrients your plant requires using a selection of nutrients and nutrients additives, giving you more control. Some growth medias come with water holding porous rock, which means if the growth media starts to run dry their is some water retention stored with it.
Applications for different Hydroponics and Grow room Growth Media.
Growth Media is used throughout a plants life cycle, from seedlings to cuttings and through to adulthood – Plants need growth media.
Hydroponics Rockwool.
Rockwool is a inert medium, completely free of nutrients and is usually available in a pH balanced form (although some Rockwool may be slightly alkali). Rockwool can be purchased in a wide variety of forms for variety uses including : cubes for propagation, shredding mixes (with coco or polyurethane foam) known as ‘mapito’, horizontal slabs for trough systems (‘Exact’ slabs), slabs for use in vertical growing systems such as the Agrowtent (‘Maxxima’ slabs) and blocks for use in NFT or flood and drain systems (available in a variety of sizes). Nutrients that are formulated for Hydroponics are usually recommended for use with Rockwool.
Hydroponics Vermiculite, Diahydro, Perlite.
All of these products are made from from porous rock material meaning they have excellent water retention qualities. These products can be used on their own as a Hydroponics Growth media. They can also be used with soil or coco to give a extra water retention and air capacity: simply mix them in with the soil or coco. Usually a 50/50 mix works well, but it depends on your requirements. Diahydro has the added benefit of being rich in silica, which improves cell wall structure and defence against pest. If used on their own, all of these products require nutrients adding to your water throughout the plant’s life cycle
Hydroponic Coco Fibre / Coco Coir.
Coco is made using the outer husk of the coconut shell. It’s naturally rich in potassium and sodium, so most coco products are pre-treated by the manufactures so that they are ready to use. make sure to check when you purchase coco whether it has been pH buffered and washed: some kinds of coco may need to be flushed through a couple of times with water at pH 6.0 before plants can be put in. Coco is a relatively light medium thats has good water retention without becoming soggy: it is much harder to over water coco than soil. It has a excellent air capacity of around 30% which aids root growth and nutrient uptake. Coco contains a naturally occurring fungus called Trichoderma that helps prevent disease and aids root development. Due to gradual leaching of potassium from the coco. It is strongly advised to use a coco-specific nutrient.
Hydroponics Clay Pebbles.
Baked clay pellets are suitable for Hydroponics systems in which all nutrients are carefully controlled in water solution. The clay pellets are inert, pH neutral and do not contain any nutrient value. We consider expanding clay to be an ecologically sustainable and re-usable growing medium because of its ability to be cleaned and sterilized. Hydroton clay pebbles come pre-washed but its recommended that they are rinsed before use to remove and dust produced during transport.
Hydroponic Soil Mixes and Organic Soil.
The soil stocked at Holland Hydroponics are made up from different substances to achieve certain properties. Some soils will be fertilized so that minimal additions are needed during the growing stage. others will contain little nutrition, giving you greater control of what your plants receive.
Soil Mix Ingredients – Explained.
Sphagnum Peat Moss : Increases the soil’s capacity to hold water and nutrients.
Garden Peat Moss : Increases acidity and the soils capacity to hold water and nutrients.
Worm Manure / Worm Humus / Worm Castings : Natural fertiliser to enrich poor or depleted soil.
Vermiculite : (See Vermiculite, Perlite, Diahydro).
Perlite: (See Vermiculite, Perlite, Diahydro).
Coco Coir : (See Coco Fibre).
Diahydro: (See Vermiculite, Perlite, Diahydro/0.
Bone Meal : A slow-release fertilizer, bone meal is primarily used as a source of phoshorous.
Beneficial Microbes : Bacteria and fungus that prevents diseases and increase nutrient uptake.
Lime : Raises the pH of the medium.
Bat Guano : Contains high levels of phosphorus and nitrogen. Also know as a natural flavour enhancer.
