Know before you buy
The vertical fiber orientation is designed to improve water distribution and re-saturation. This structure allows nutrient solution to move evenly through the slab, preventing dry spots and ensuring roots have consistent access to moisture.
These slabs are ready to use right out of the box. They feature pre-cut holes for planting, which simplifies the setup process and saves time during transplanting.
Because the stone wool is inert, it contains no nutrients of its own. You will need to provide all necessary nutrients through your irrigation system, which gives you complete control over the plant's feeding regimen.
These slabs are intended for single-use applications. Reusing stone wool can lead to root rot, pathogen buildup, and structural degradation, which may compromise the health and consistency of your next crop.
Yes, the PARGRO slabs are versatile and work well for a wide range of crops, including both vegetables and flowers. Their uniform density provides a stable environment for various root systems.
