High-Grade Hydroponic Grow Media Choose from a large selection of different media types: Cultiwool Rooting Plugs Ideal for taking cuttings or for germinating seeds. Choose between small and large versions. One quick tip: you can get more cuttings taken in the same space with the small versions, but the trade-off here is that they can dry out quicker, so be sure to keep a close eye on them. Once they're rooted, you can transfer them to a 3-inch or 4-inch rooting cube (see below). Cultiwool Cubes 3-inch and 4-inch versions are available, with a choice of small and large holes (to suit small or large rooting plugs). There's also a 6-inch version with large hole, which is sometimes refered to as a 'Hugo Block'. Mapito 80 Litre Bag These bags allow you to fill your containers or net pots with Cultiwool, using it in the same way that you might use clay pebbles or coco. Cultiwool Slabs These slabs are typically used in specialist hydroponic grow systems, namely NFTs. Choose between 1000mm x 150mm x 75mm or 1330mm x 150mm x 75mm versions.
