Hello, Been reading up on coco for a while now and decided to get some plants started. I got 2 different types of coco-peat brick, one with a slow release fertiliser one without. Slow-fert: http://www.brunnings.com.au/products/factsheets/NitroPeatBrick.pdf Normal: http://www.brunnings.com.au/products/factsheets/easywetta CoirPeatBrick.pdf Planning to do a tub of each, with 30% perlite mixed in. Is the slow release fertiliser appropriate for growing ? The NPK ratio is 16:3:1.
