Cultiwools’ stone wool growing slabs provide the final stage for growing crops. With the different dimensions and the possibilities of different plant holes pre-cut in the slabs, we have a solution for almost every growing system and required substrate volume per crop.
Our Cultiwool slabs come standard with a vertical fibre orientation but on request we can also deliver a horizontal fibre in our stone wool slabs. Cultiwool stone wool is used worldwide by professional cultivators. It allows them to grow top quality produce with fewer inputs. The basis of a successful crop for a longer period is a substrate with a superb and consistent homogeneity.
Our growing slabs come in different dimensions and packaging units.Download the Cultiwool product leaflet
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.
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.
