Grodan Rockwool Vital Slabs

The Grodan Rockwool Vital Slab represents the finest Dutch growing technology.

• These slabs are wrapped in a co-extruded white/black plastic film designed to keep light away from the slab.
• DIY systems using aquatrays to hold slabs can easily be built to any size grow room.
• Slabs fibres are aligned in a vertical direction helping to promote the rapid initiation of vegetative growing at the beginning of cultivation.
