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

CANNA Aqua Clay Pebbles

CANNA Aqua Clay Pebbles are baked clay pellets that form an ideal substrate for use by experienced growers. Aqua Clay Pebbles are ideal for growers who want to control the application of nutrients and the humidity level of their plants throughout the entire cultivation process.

Advantages of CANNA Aqua Clay Pebbles

  • CANNA Aqua Clay Pebbles have both high porosity and high air content which stimulate the development of strong roots that grip the substrate well. Strong roots mean bigger yields.
  • Aqua Clay Pebbles are inorganic, have a neutral pH value, are fungus free and do not rot.

Canna Coco Professional Plus 50l Bag

£14.00 £12.00 incl. Vat

CANNA Coco Professional Plus

CANNA Coco Professional Plus is a coco-based growing medium that offers the gardener and his plants many advantages in comparison with other substrates:

  • CANNA Coco Professional Plus is a pure, organic product with a homogeneous structure and has had a full buffering, eliminating the side effects of growing on coir, as coir could consume some of the nutrients.
  • CANNA Coco Professional Plus is free of harmful viruses and soil diseases, thanks to CANNA’s unique production process.
  • CANNA Coco Professional Plus has a complex water/air system that provides the ideal conditions for growing plants.
  • CANNA Coco Professional Plus contains a special mould (Trichoderma) that protects the plants against soil diseases.
  • CANNA Coco Professional Plus can be used a number of times and makes an excellent potting mix improver after use.

CANNA Coco Professional Plus = R.H.P. quality

CANNA Coco Professional Plus consists of 100% coco flakes. Specially selected prime Indian coconuts form the base for CANNA Coco Professional Plus. Not touching the outdoor ground in the complete production process ensures the end product is free of weeds or soil diseases. Washed in fresh water means no salts are present. This makes it the best growing medium of the future.

The production process is subject to strict quality controls so we can vouch for this product’s quality.

CANNA Coco Professional Plus carries the strictest R.H.P. quality mark. Actually, the quality of this product goes well beyond the R.H.P. standard. In short, the R.H.P  quality mark means that the product is free of weeds. The R.H.P. inspection is not limited to the finished product but covers the sourcing and processing of raw materials all the way to the bag.

CANNA’s buffering process allows us to ‘pre-program’ the medium to a certain age. This ensures you get the same consistent, high quality material time after time.

Ecothrive Coco Clay Mix 40L

£14.00 incl. Vat

The ideal mix of 40% coco coir and 60% clay pebbles for optimum water holding in hydroponic systems, pre-blended with Ecothrive Charge for an unbeatable biological boost. 

Ecothrive Charge is comprised of 100% premium organic insect frass. Thousands of production-focused growers across the UK already mix Charge into their coco coir every time they pot up. With Ecothrive Lite Mix you can enjoy all the benefits of Ecothrive Charge straight out of the bag.

Why Clay Pebbles?

Coco coir has a high water holding capacity, which does not make it the best option for use in frequently irrigated hydroponics systems, such as Flood and Drain systems. To tailor the characteristics of our ‘charged’ coco coir and make it perfect for these applications we have blended 60% clay pebbles with 40% coco coir to reduce the water holding, creating a mix with fast drainage and improved air space. Plants grown in Ecothrive Coco Clay Mix will have improved root growth, quicker establishment, faster growth rates in Hydroponic systems and be far less prone to the effects of over-watering, a common problem in Flood and Drain Systems. Coco Clay Mix is ideal for:

  • Flood and Drain Systems 
  • Autopot systems 
  • Drip Irrigation Systems         

Evenly Blended, Ready to Use

Most coco coir mixes contain no nutrients with very low levels of beneficial biological activity.  Now with Charge conveniently pre-blended into your coco mix your plants enjoy a balanced, organic source of primary nutrients along with a boost of beneficial bacteria, chitin derivatives and naturally occurring Trichoderma.

Ecothrive Coco Clay Mix uses RHP certified, buffered coco that has been pre-blended with Charge at 1% by volume. This mixing ratio makes it ideal for almost all applications. However, if you are potting up plants into their final pots you can add more Charge into the mix at the rate of 10ml per L to provide a nutritional kick and ultimately, a bigger boost.

Switch to Coco Clay Mix and enjoy stronger, healthier and more vigorous plants that you are less likely to over-water when compared to ‘uncharged’ 60/40 coco mixes.
