Bigger is not always better.
Jumbo is a particular good choice when you want to use a big block in an ebb/flood system. When you use rockwool in ebb/flood system that is over 4”:tall the upper part of the block tends to get drier and you see more salt build up. By using The 4” Jumbo for ebb/flood you will have great water distribution throughout the block—and great results.

Why did the Grodan® company create Pargro®?

We believe Grodan rockwool to be the best in the world using the most advanced technology for each product. But we also recognized the need for a quality rockwool able to compete in the market with the lower-priced brands that do not deliver consistency, uniformity or high yields. Pargro delivers Quality. Performance and Price. Try the new generation of Pargro and you will see the difference.

What is the difference between Pargro and Grodan?

  • Pargro uses only one basic type of wool for propagation, one for blocks and another type for slabs. The wool used in Grodan is configured specifically with Delta® Technology for each Grodan product that is made.
  • Pargro slabs are wet slabs only (same wetness type as the Grodan Classic slab)
  • The Grodan line includes a larger variety of products and sizes.
  • Pargro marketing and product support is limited, unlike for Grodan.
