Amount: single
Sale price£8.95


Introducing Grodan Big Mama Rockwool blocks! Indoor growers have waited a long time for these impressive Rockwool cubes to become available to the UK market. The huge 8-inch cubes have twice the volume of the ever-popular Grodan Hugo Blocks and are extensively used in the USA to bring medium-sized plants to full maturity.

Benefits of Big Mama Rockwool Cubes

  • Large enough for a plant to complete its full lifecycle
  • Lets you transfer a smaller Rockwool cube on top
  • No pre-cut hole means plants can sit on top easily
  • Suitable for Wilma and drip-based feeding systems

Also available by the box of 18 blocks at a discounted rate!

How to Use the Big Mama Growing Cubes

Big Mama growing cubes are made of Rockwool - the ideal substrate for growing your plants. This is because Rockwool has a perfect air to water ratio and nutrient-holding capabilities, meaning growth is fast and strong.

Arriving at a whopping 8” square, Big Mama blocks are the largest made by Grodan and contain double the amount of wool in the Hugo Block. And the lack of a pre-cut hole means you can place a young plant on top once it’s outgrown its current block.

Using Big Mama Cubes with Hydroponics

Big Mama growing blocks are ideal to use with a top-fed drip system on a run-to-waste or recirculating set-up. But can be incorporated into flood and drain systems and even be hand-fed with small plants.

You can fit four of the Big Mama Rockwool blocks perfectly into a Wilma 4 Pot System or use 8 in the larger Wilma 8 Pot System
