PRO7 | COCO BRICK

The PRO7 COCO BRICK produced by Jiffy is already a favoured choice for professional cut-flower growers using hydroponic pot systems, thanks to the reliable consistent quality of coco coir, better temperature control and versatility.

The PRO7 COCO BRICK is a 100% RHP Certified brick of pressed and dehydrated premium mixed fibre coconut coir pith. It is washed/buffered making it ideal for an all-round potting substrate that is easy and discrete to transport and store, aids faster rooting and develops stronger plants. Simply rehydrate PRO7 COCO BRICK with 3.5/4 litres of water and watch it expand to 8 litres of exceptional quality Jiffy cocopeat. The perfect, easy to transport growing media for short-term and seasonal, indoor and outdoor crops. PRO7 COCO BRICK works perfectly in combination with Jiffy7c plugs and ROOT!T plugs.

How to use:

Mix water and nutrient in a bucket, place in your PRO7 COCO BRICK and watch it swell.
We recommend 3.5L of lukewarm water for a mix that is not quite fully wetted up, ideal for if you then wish to water in your freshly potted on plants and 4 litres if you are not going to water in your plants.

Break it up within the bucket and fluff it up to produce a uniform product with your hands or a hand fork. Now is the point at which it is best to add any further substrates you require, such as perlite or clay pebbles.
Add your expanded potting mix to a suitable pot and then add your plant. Plants propagated in Jiffy7C plugs or ROOT!T sponge plugs will have a head start, ready to thrive in your PRO7 premium substrate.

Start to feed with a professional fertiliser such as VitaLink Coco Coir nutrient proven to promote rapid root development and vigorous growth. Mix in 1-2 ml/L of each of A and B solutions to your water for seedlings and young plants. Begin to increase the dose rate once you see your seedlings or plants have established and are actively growing. Use at 3-4 ml/L of each of A and B solutions for mature plants.

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 BRICK

3.5L for a drier mix, which is perfect for plants that you wish to ‘water in’, or 4L for a wetter potting mix to plant directly into without ‘watering in’.

Lukewarm water speeds up expansion, however cold water will work just fine.

All PRO7 coco is the highest quality Jiffy mixed fibre coco peat. The difference is that loose fill bags are ready to use right out of the bag; the compressed blocks however, need to be re-hydrated but are cheaper and easier to handle and are more discrete to transport and store.

Yes, PRO7 COCO BRICKS can be blended with soil, perlite, clay pebbles and other such substrates, or use it as a stand-alone growing medium.

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).

Maximise your yield with Vitalink professional feeds and additives

VitaLink Coco Coir Grow contains all the nutrients needed to perfectly partner with PRO7 potting mixes. From the start of cultivation, they are delivered in a form that maximizes rootzone development and nutrient uptake.
Considerable attention has been given to the interactive processes that exist between the feeding and the potting mix, ensuring that optimal intake and growth potential is achieved.

This ‘pairing’ of nutrient and growing medium can be seen in use through healthy, fast growth and strong root development.
The pairing starts with superior propagation and for this we recommend VitaLink Plant Start. It has a unique calcium/boron combination that rapidly sets rooting on cuttings and develops strong seedlings. A strong start in life is the key for achieving top results.
VitaLink Coco Coir Max is a coco nutrient that contains all the nutritional elements that the plants need, when growing in a coco based substrate, from propagation through to the flowering cycle.

As an addition to your base feed, we recommend trying additives such as VitaLink Turbo+ that will optimise the nutrient uptake capabilities of your plant, while also assisting to strengthen it, working as a catalyst to a higher yield and better taste/aroma.
