Pargro is the leader among affordable horticultural rockwool.

Made right in the Grodan factory, you can be assured of a high quality product at a great price. Pargro Quick Drain (QD) blocks are up to 14% drier than Cultilene Comfort blocks. Pargro QD slabs are up to 10% drier than our previous Neptune slabs. Jumbo is a particularly good choice when you want to use a big block in an ebb and flow system. If you want a drier top, then opt for the Biggie in your system, since capillary movement will generally not reach above 4 in a block on most flood tables.

  • Value priced - no frills saves you money
  • Half case sizes in plain boxes
