Growing blocks

Not only can you expect the highest quality stone wool in the market, but Cultiwool is also the first to introduce highly appreciated cross grooves to improve water flow under the block, and the black/white foil to prevent algae growth.

Drain grooves 

The Cultiwool substrate blocks are provided with drain grooves at the bottom to improve the waterflow under the block. This is especially useful when the substrate blocks are placed on cultivation tables and concrete floors. Another benefit of the drain grooves under the block is that it will limit the contact surface with the ground. This will avoid bringing diseases in to the plant via weak roots often in combination with too high temperatures.

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.

Cultiwool has the following characteristics:

• Superb air to water ratio
• A fiber structure that holds water longer
• Less resistance for the roots to grow in the block, resulting in better roots for "fragile" crops
• A fiber structure that enhances faster initial rooting
• All products are uniform and comparable with each other
• Guaranteed firmness
