DIY Seed Raising Mix

I make my own seed raising mix to ensure that my seed trays have every chance of success whilst germinating. As our summers get very hot, moisture seems to be the problem with seedlings. By adding coconut fibre (coir peat) bigger healthier roots grow and require less water, as the product has a higher water holding capacity. The addition of vermiculite also enhances moisture retention. This recipe makes up to 15 litres depending on what coir product you use.
