Big Mama Delta cube

Grodan Big Mama Rockwool blocks are finally available to the UK market! 

The huge 8-inch cubes are extensively used to bring medium-sized plants to full maturity and have twice the volume of the Grodan Hugo Blocks.

Benefits of Big Mama Rockwool Cubes

• Big enough for the entire lifecycle of a plant to complete
• Smaller Rockwool cubes can just be placed on top
• No pre-cut hole means plants can sit on top
• Ideal for drip-based and Wilma hydroponics systems
• They come in a box of 18 eight-inch growing blocks
