The PRO7 COCO BLOCK produced by Jiffy is the perfect choice for growers that use a lot of coco and want it to be easy and discreet to transport and store, but more cost effective than buying multiple COCO BRICKS. How to use: Place your PRO7 COCO BLOCK into a large wide container such as a Garland 1m tray or wheelbarrow, premix your water and nutrient in a bucket then add to your block and watch it swell. We recommend 30L of lukewarm water for a mix that is not quiet fully wetted up, ideal for if you then wish to water in your freshly potted on plants, and 35 litres if you are not going to water in your plants. Break it up within the bucket as it swells and fluff it up to produce a uniform product with your hands or a hand fork. This can take 15 to 20 mins. 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 Grow, a vega nutrient proven to promote rapid root development and vigorous early 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, we recommend a half strength CalMag supplement such as Vitalink CalMag (0.5ml/L) during the growth stage.
