Growing Media Information
Hydroponic and Soil Media
In any soiless gardening system that uses a media its purpose is solely to anchor the roots and hold moisture/ nutrient for the plant. The media itself is inert and contains no plant nutrients. Made of various inert materials it will not decompose, nor harbour any soil borne pests or disease.
The plants complete nutritional needs are met by the special nutrient mixes that you add to the individual system.
We offer a range of growing media that have been selected due to their high quality and superior capacity for holding nutrient solutions, while still retaining a good balance of oxygen and moisture.
Typical Hydroponics Media Are:
Hydroton Clay
Hydroton is a special kiln fired clay based aggregate that is super heated and formed into small 'marbles' usually between 4mm to 16mm in diameter. The inner core structure is porous and will absorb and release nutrient and water to the plants as required. Hydroton will not compact; this ensures excellent aeration for the root zone. Hydroton is completely reusable and will last indefinitely, making it real value.
Hydroton is an excellent medium for pot culture, to mix with Canna Coir and for use in Ebb & Flow systems. It is especially popular with Orchid growers. Hydroton will readily accept transplanted seedlings started in Rockwool or any other traditional planting mix.
Canna Coco Coir
Coconut Coir is rapidly becoming the media of choice for both soil-less gardeners and soil based gardeners who are concerned about the depletion of rare peat bogs in the world. Coco Coir is a waste material from coconut production and is 100% renewable.
Canna Coco Coir is the market leader in Hydroponic Coir media, this is due to the high quality and pretreatment necessary for coir to be used in soil-less gardening. Canna Coco Coir has been pretreated or washed to eliminate the high levels of salt often found in the raw material. Other Coconut Coir's on the market are often unsuitable for soil-less gardening due to these high salt contents.
Horticultural Rockwool
Made from molten basalt rock spun into a candy floss like fibre, Grodan Rockwool is a popular medium used by hobby gardeners and commercial growers alike.
The material is available in small starter cubes for propagating seeds or cuttings, through to large slabs in which plants will happily grow for months and months.
Soil Media
Bio-Bizz All Mix
All-Mix was developed especially to be the best potting soil for organic cultivation. It consists of 20% sphagnum peat moss, 35% garden peat, 10% high quality organic worm manure, 30% perlite and 5% Pre-Mix. Watering is sufficient for plant growth, however, Fish-Mix and Alg-A-Mic may be used during the growth phase as added stimulants.
Canna Professional Plus Soil Mix
Contains a range of peats and perlite as well as trace elements and various chelates. This pH neutral media contains sufficient feed for the first growing week. Made using first class organic raw material and is free from viruses and soil diseases.
Other Media
Other media that are often used in Hydroponics include Sand, Gravel, Vermiculite and Perlite. In fact any media that is inert and pH neutral can be used, but other issues such as compaction and air to water ratios are very important to consider.
