Carefully designed with relatively high density, low drainage, and just the right amount of starter nutrients, ROOTCUBES® Plus is ideal for propagating cuttings that are slow to root. Water uptake is made quicker and easier by a fine-cell design that improves contact between the media and the end of the cutting. Plus, its higher density grips the cuttings tightly to keep them securely in place. Best of all, cuttings are rooted significantly faster compared to other hydroponic substrates.
