I bought this couple of times. A year ago I used it for the potting soils and was very happy. I am using it since then. Great product.

Have been using this as a staple with my coco-coir potting mix, (sometimes with added perlite or sand depending on plant). It's been absolutely essential to maintaining a healthy and alive potting mix when using coco-coir, whether it be in 50mm plugs, small pots or larger containers for almost any plant, it is the must-have kickstarter and I couldn't recommend it more, especially if you want to maintain a soilless mix and minimise the risk of harmful bacteria and fungi, as well as gnats and other pests often introduced through other organic additions to soilless mixes.
