Obturo
Obturo® is a plant plug that can be adjusted to meet customer requirements. This way, Obturo® offers all the flexibility needed to perfect the cultivation process. Obturo® has been specifically developed to facilitate easy rooting. The plants’ roots will really quickly penetrate the entire plug. The unique composition of the substrate combined with a binder makes it easy to rewet the Obturo®. Obturo® plugs can be processed by hand, but the plugs are also suitable for automatic handling.
Fibre-Neth plugs
Fibre-Neth® plugs mainly consist of coco peat and a binder. Fibre-Neth® plugs retain their compact form which, combined with the unique characteristics of coco peat, ensures a high air content. Due to their unique properties, Fibre-Neth® plugs can be controlled well, ensure fast rooting, optimal root development, and can be planted quickly.
Forteco Substrate Slabs
Forteco coco slabs are completely 'ready to use'. Drainage slits and plant holes are pre-cut and dripper holes are drilled. Coco slabs have a high air-holding capacity, which affords good drainage capacity and excellent crop management. Plants root very easily in coco slabs due to their unique air/water ratio and the roots are distributed throughout the entire substrate.
Custom Substrates
Not all potting soil mixtures are suitable for all crops. That is why we consider our customers' wishes and the growing requirements of the crop when composing a potting soil mixture. We do this in consultation with the grower and by using our expertise as a potting soil manufacturer. This process always involves custom solutions.
When composing a mixture we consider aspects including crop, pot size, potting method, (starter) fertiliser, dripper system and growing conditions.
