Grodan ParGro Quick Drain Biggie 6 inch x 6 inch x 6 inch Block

Pargro line has been modified to be the driest value-priced Rockwool on the market. Pargro is the leader among affordable horticultural Rockwool. There are other brands that offer the same low price, but you end up sacrificing quality. Not with Pargro! Since it is 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.
