Coco Product


One of the most stable COCO 100% pith substrates on the market today, with Active Trichoderma
Well suited for growing short cycle and
fast-growing plants in pots.

Peat Free

PRO7 COCO is one of the most stable coco substrates on the market today. 100% pith manufactured from the mature coconut husk and never compressed to retain its structure. Mature coconuts mean the pith will decay slower, thus giving a more stable media over the growing cycle.

RHP certified. Washed and buffered with calcium and magnesium to RHP standards - extracting unwanted elements such as potassium, sodium and chlorides. Providing a clean substrate with a stable pH value, perfect for growers who want ultimate control over their fast-growing plant's fertigation. PRO7 COCO has excellent water retention and airing properties, well suited for growing short cycle and fast-growing plants in pots. Develops vigorous root systems and strong growth. PRO7 COCO produces high yields with all nutrients on the market, however some of the highest yields in our trials have been achieved in combination with VitaLink Coco Max with the addition of the additives VitaLink CalMag and VitaLink Turbo+.

How to use:

Firstly, we recommend having the optimum start by propagating your seedlings/cuttings in Jiffy 7C plugs or ROOT!T, fed with VitaLink PlantStart which supplies the perfect ratio of boron to calcium, proven to promote rapid root development and vigorous early growth. Then, transplant into PRO7 COCO and feed from day one with a high-quality professional plant feed, such as VitaLink Coco Coir Max.

Media bags are transported on pallets and can become compacted during storage. Before transferring your substrate into pots, we suggest you ‘fluff up’ your medium to break up any compressed lumps. An easy way to do this is to tap the side of the bag, like you would fluff up a pillow. Pour into your pots and run your fingers through the substrate, checking for any lumps that may still be in it and break them up. Settle the mix by tapping edges and base of pot and plant up.

Ensure the entire medium is completely soaked before planting on to make sure your plants get enough to feed on.

To pre-soak PRR7 COCO substrates, apply a 3/4 to full strength feed until run off appears. Run off is the feed that gathers underneath pots in your saucer or tray after watering.

Hand watering: We recommend using VitaLink Coco Coir nutrients and following the feed schedule. PRO7 COCO prevents over-watering due to its structure, but attention needs to be paid to avoid nutrient reabsorption from pots/container sitting in any runoff.

Dripper systems: PRO7 COCO is best fed little and often. A dripper system is perfect for this. Please note that the particles in COCO can easily block dripper lines, so if using a re-circulating system, we recommend fitting a filter and check it regularly.

Always check the water quality in your area and ensure you are using the correct variant – either hard water or soft water. In very soft water areas, or at the onset of any calcium deficiency, we recommend a half strength CalMag supplement such as Vitalink CalMag (0.5ml/L) during the growth stage.

Frequently asked questions about COCO

No. PRO7 is already fully washed with no salt content and buffered, all to the high quality RHP standard. You simply need to pot your plant and start feeding with a high-quality coco nutrient such as VitaLink Coco Coir.

From day one. Add your chosen nutrient to the coco in line with the nutrient feed chart. Always start with a reduced feed concentration and then build up the amount you feed as the plant grows.

Yes, they are made of the same COCO pith, however they have been dried and compressed - easy to transport but need to be expanded back into a usable form, PRO7 COCO is ready to use out of the bag.

Benefits of PRO7 COCO

  • Completely buffered substrate with stable pH.
  • Guaranteed low EC value.
  • Airy structure.
  • Optimal root development.
  • Peat Free.
  • Premium Quality RHP washed and buffered coco.
  • Low watering frequency needed.

What is the RHP?

RHP certified substrates guarantee an optimal start of your crop. The RHP certificate ensures that the substrate complies with the quality requirements concerning, for instance, air content and water uptake, pH, EC and nutrients. For the production of RHP substrates, only phytosanitary clean raw materials are allowed to be used; the processes and products are regularly checked by independent inspectors. In short, quality of substrates is the basis for a good start of your culture.

Growing media with the RHP quality mark has more benefits:

  • The product and production process meet the RHP standards based on general, chemical, physical and phytosanitary requirements set up by specialists including growers.
  • Products with the RHP Horticulture quality mark are free of contamination with heavy metals, radioactivity, weeds, seeds, insects, plant and human pathogens, according to the RHP standard. Therefore, additional treatments like disinfection, sterilisation and/or fumigation are not necessary and are even undesirable.
  • The chemical and physical specifications of each particular substrate have to be predefined, ensuring that each delivery is consistent in properties.
  • Products with the RHP Horticulture quality mark, that consist of several raw materials, must be mixed in such a way that the properties of the batch are the same throughout the batch.
  • All product samples are analysed at RHP acknowledged laboratories. From each delivery, an RHP certified company has to retain a sample under specified conditions. RHP has developed parameters to measure and specify, like water uptake characteristic (WOK) and structure stability (respiration method).
