Cultiwool blocks - low density rockwool for fast rooting from plugs.


From the melting of the basalt, until the transformation to germination plugs or growing blocks, everything takes place under close supervision. Doing so gives Cultiwool the opportunity to control the entire chain, and that makes our products more uniform, firmer and more productive.

Cultiwool Features:

  • Superb air to water ratio
  • A fibre structure that holds water longer
  • Less resistance for the roots to grow in the block, resulting in better roots for "fragile" crops
  • A fibre structure that enhances faster initial rooting
  • All products are uniform and comparable with each other
  • Guaranteed firmness

Cultiwool's Blocks are ideal transplanting Cultiwool plugs.

Each case contains 216 blocks. Choose by the case or save money with a pallet of 10 cases (2,160 blocks)
