Grodan Improved Block Big Mama without hole 20×20×20cm, 18 pcs.

Grodan Improved Block Big Mama 20×20×20 without hole (Pack of 18)

The Grodan Improved Big Mama is the upgraded version of Grodan’s largest available rockwool block. With more than twice the substrate volume of a Hugo block, it provides strong support for large plants throughout the entire grow cycle. Its improved technology delivers better re-wetting and even water distribution over the full block height - helping roots penetrate and utilize the entire substrate volume effectively. The No hole design also keeps it flexible for stacking smaller blocks on top.

Use & application

• Use as a final block for large plants and long cycles
• Ideal when you need uniform moisture distribution and stable water management
• No hole: great for placing rooted starter blocks on top
