Cultiwool 6 in Wide Stonewool Slab - 36 x 6 x 3-in - Fully Sealed - 16 Count

Consistent Root-Zone Substrate for Hydroponic Systems - 16 Slabs

Uneven substrate makes watering and feeding harder to manage from one plant to the next. Cultiwool stonewool slabs give you a uniform, fully sealed medium with vertical fibre orientation, so you can run a steadier root zone through vegetative growth and flowering.

This unit holds 16 slabs, each 36 x 6 x 3 in. That quantity suits growers who run a regular indoor hydroponic setup, or small commercial rooms that need a repeatable substrate across a bench or gutter line.

Key Features & Benefits

• Stonewool construction — a widely used hydroponic medium that supports controlled irrigation.
• Fully sealed slabs — a wrapped slab keeps the medium contained and easy to handle.
• Vertical fibre orientation — fibres run vertically as standard.
• 6 in wide format — a narrow slab that fits many hydroponic layouts.
• 16 slabs per unit — one purchase covers a full run.

Who Should Use Cultiwool 6 in Wide Slabs
