Rock Wool Growing Slab 4 Openings 1200×200×100mm Maximum Yield Per Unit Area

This rock wool growing slab measures 1200×200×100mm with 4 planting openings on top. It combines the triple advantages of 100mm height (deep root), 200mm width (wide root zone), and 4 holes (dense planting), making it the top choice for commercial greenhouses pursuing maximum yield per unit area.

Suitable for crops that tolerate dense planting and require deep roots, such as cherry tomatoes and peppers. With a total volume of 20 liters shared by 4 plants, each plant's root zone of approximately 5 liters.

• Ultra-high density planting of cherry tomatoes and cocktail tomatoes
• Single-row dense planting of peppers and chilies
• High-density cultivation of greenhouse cut flowers (snapdragon, delphinium)
• Fruit vegetable production in plant factories

• 4 holes + deep and wide design, higher yield per slab, suitable for greenhouses with high land costs
• Hydrophilic agents added to rock wool ensure uniform moisture in deep root zones
• After use, compressed and baled for recycling into insulation materials, closed-loop utilization
