Cultiwool Mini-Blocks 1.5" x 1.5" x 1.5"

Description For a successful crop production Cultiwool starter plugs are known for their uniformity and firmness, and are ideal for growing crops in a hydroponic system. Our high quality stone wool is a clean and inert product. Therefore, it provides a sterile environment and does not contain any harmful bacteria or pollutants which can affect root- and shoot development. It does not lock up or release any substances, ensuring all water and nutrients are available to the plant.   Use the starter plugs for your start prior to transplanting into our larger growing blocks. Our starter plugs come in different dimensions and packaging units.   Uniformity A homogeneous stone wool product is essential for unrestricted and regular root growth. Cultiwool stonewool produced in Europe is the highest quality stonewool in the market for hydroponic systems. Stonewool used in Cultiwool is certified by RHP. Therefor Cultiwool offers maximum uniformity to optimally control water and nutrient application. The result is a uniform crop that will result in higher yields, better quality, and less energy usage.   Fast uptake of water Reliable initial saturation is key to avoid dry spots in the substrate. Dry spots will create salt build up which results in an unbalanced block and should be avoided at all times. Cultiwool substrates have a faster and easier water uptake due to the high quality of stonewool.This explains why stonewool used in Cultiwool is the only stonewool board in the highest category of RHP related to initial wetting-up.   Total control Water, EC and pH distribution can be very well controlled with Cultiwool rock wool substrates, both vegetative and generative, depending on the needs of the crop and at different moments during the cultivation.   Unique water distribution Cultiwool is the first to introduce – as quality leader – the donut ring on big blocks to improve the water distribution. Already for many years Cultiwool has the highly appreciated drain grooves under the big blocks to improve the waterflow under the block, specially on tables or small gutters.
