Crafted from high-quality European stonewool, these premium
Cultiwool blocks are engineered for growers who demand reliability and performance.

The design incorporates cross grooves on the bottom to enhance drainage and minimize contact with the ground, significantly reducing the risk of root pathogens. Additionally, each block is wrapped in black and white foil to prevent algae growth and manage light exposure, ensuring your focus remains on plant health, not pest control.
