In many hydroponic systems such as NFT, Aeroponics and Deep Water Culture, the growing media is very minimal, with the majority of the root base growing in the growing system and nutrient solution. With other growing methods like Auto pots, Hand feeding or drip irrigation the growing media is more substantial.
We have an extensive range of media available for hydroponic growing, as your choice will be driven by the growing system you have decided to use. Each type of growing media has its benefits and drawbacks. It is about finding what suits your style of growing and which you can use to obtain the best results when growing your prized plants

Directions of Use:

Loosen the CANNA Terra Professional and fill the pots, compressing the medium slightly. Add water until a little begins to drain through and then place the plant in the CANNA Terra Professional.

Watering

Depending on the size of the pot, growing conditions and the plant's growth stage, adjust the amount of water given to the needs of the plant in question. Under normal conditions, adult plants evaporate 4-6 litres of moisture a day, per m2. For larger plants, use 5 litre pots or larger. The larger the pot, the more constant the root environment will be. If you use run-to-waste, make sure that there’s sufficient drainage; you may want to place a thin layer of hydro-granules in the bottom of the pot for air and drainage. CANNA Terra Professional is a product, homogenous in structure, natural and free of harmful viruses and soil diseases. CANNA Terra Professional has a complex water/air system that creates conditions ideal for virtually every form of cultivation. After use, CANNA Terra Professional makes an excellent potting mix improver. CANNA Terra Professional's plastic packaging material is 100% recyclable.

£14.00 incl. Vat

Ecothrive Coco Lite 50L

The perfect mix of 70% Coco Coir and 30% Perlite for optimum aeration, pre-blended with Ecothrive Charge for an unbeatable biological boost.

Why blend coco with perlite?

Perlite increases the amount of air within the mix and reduces the water holding capacity. This creates a lighter mix with better drainage and improved resistance to compaction.

Plants grown in Ecothrive Coco Lite will show improved root growth, quicker establishment, a faster growth rate and are less prone to the effects of over watering than pure coco coir.

BioBizz All Mix – 50L

£14.00 incl. Vat

What is All·Mix?

All·Mix literally does it all for you – creating the optimum environment for plants to flourish throughout the year. This heavily pre-fertilized substrate mixture emulates a rich outdoor soil with a full micro active ecosystem. It’s been designed to have enough nutrient-fuelled power to sustain lush growth for a couple of weeks, without any need to add any extra fertilizer.

The pH and EC values

Biobizz products only contain natural organic elements rather than mineral salts such as magnesium or sulfates that you might find in synthetic fertilizers. This gives All·Mix a high Electrical Conductivity (EC) value. And while its organic elements are impossible to measure, they do have a self-regulating system, which helps maintain the pH values at the correct level.

How to use it?

When using All·Mix for the first time, moisten it with water and leave to stand for 36 hours. This gives the Pre·Mix active fertilizer and microorganisms inside the substrate a chance to start working their magic before the plants goes in. Keep the soil slightly warm at all times – if it’s too cool, the microbial activity slows down, which makes it more difficult for the plants to grow. You also want to allow the soil to dry out between each watering. Because, as the All·Mix substrate dries out, fresh air gets in, which helps the soil to breathe.
