Grodan Pargro QD Biggie Block, 6" x 6" x 6" with Hole, Case of 64

Value-priced stonewool without the quality compromise. Pargro Quick Drain blocks are made in the Grodan factory but formulated to run drier than standard rockwool, up to 14% drier than comparable comfort blocks, giving fast-draining root zones that are forgiving of heavy watering.

Why growers choose Pargro QD Biggie

• Quick Drain formulation: holds water where roots need it while shedding the excess, so blocks are up to 14% drier than Cultilene Comfort blocks.
• Big 6 x 6 x 6 block: plenty of root zone for large plants through a full cycle, with a pre-formed hole for direct plug transplanting.
• Made for flood tables: a great big-block choice for ebb and flow systems, since capillary rise generally won't reach above 4 inches, keeping the top drier.
• Grodan quality, value price: manufactured in the Grodan factory for dependable uniformity at an affordable price.
• Bulk case: 64 blocks per case for high-volume production.

How to use

Condition the block, transplant a rooted plug into the pre-formed hole, and grow on your flood table or in your preferred system. Water to your usual schedule and let the Quick Drain formulation manage the excess.
