Grodan Hugo Grow Wool Block 150mm x 150mm x 150mm | Full Cycle Rockwool Block

One Block. Full Cycle. Zero Compromises.

Most growing media are built for one stage. The Grodan Hugo Grow Wool Block is built for the whole journey — from transplant through to harvest. At 150mm x 150mm x 150mm, this large-format grow wool block gives your plant's root system the space it needs to develop fully, while Grodan's precision-engineered mineral wool structure maintains the air-to-water balance that drives consistent, vigorous growth.

If you're running a run-to-waste or high-frequency fertigation system, this is the block it was designed for.

Why Growers Choose the Grodan Hugo Block

• Full plant life-cycle support — large enough to take a plant from transplant to harvest without switching media mid-grow.
• Engineered for high-frequency fertigation — the Hugo's structure handles frequent watering cycles without waterlogging, keeping oxygen available at the root zone.
• Run-to-waste system ready — designed to work with run-off tray setups in grow rooms and propagation tents.
• Compatible with Netafim Netbow feeding rings — drop straight into your existing drip irrigation setup.
• Consistent Grodan quality — uniform density and fibre structure cube to cube, so every plant gets the same environment.
• Simple setup — pre-soak, plant, connect your timer and nutrient solution. That's it.

How to Prepare Your Hugo Block

Always pre-soak the block in a pH-buffered nutrient solution (target pH 5.5–6.0, EC matched to your crop stage) before planting. This conditions the block to the correct EC and pH, ensuring the root zone is stable and ready to support strong early root development from day one.
