Grodan Pargro QD Jumbo Block 6 in x 6 in x 4 in w/ Hole (64/Cs)
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.
