The Grodan ParGro Quick Drain Block 4 x 4 x 4in w/ Hole is the ultimate choice for value-priced Rockwool with unmatched dryness. As part of the renowned Pargro line, these blocks have been specially modified to provide exceptional quality and performance while maintaining an affordable price point.
When it comes to horticultural Rockwool, Pargro stands out as the leader in affordability. While other brands may offer similar low prices, they often compromise on quality. With Pargro, that is not the case. Being manufactured directly in the Grodan factory ensures that you receive a product of the highest quality at a great value.
The Pargro Quick Drain (QD) blocks offer remarkable dryness, outperforming Cultilene Comfort blocks by up to 14%. For those using slabs, Pargro QD slabs are up to 10% drier than the previous Neptune slabs. This exceptional dryness is crucial for maintaining optimal moisture levels in your growing system, promoting healthy root development and preventing issues associated with excess water.
The Jumbo size of the ParGro Quick Drain Block is an excellent choice when utilizing a big block in an ebb and flow system. The larger size allows for more water retention, providing ample moisture for your plants' needs. The capillary movement within the block ensures efficient distribution of water and nutrients, supporting robust growth.
If you prefer a drier top layer in your block, the Biggie size is the ideal option. In most flood tables, capillary movement typically does not reach above 4 inches within a block. By opting for the Biggie size, you can ensure that the upper layer remains drier, preventing over-saturation and potential issues caused by excessive moisture.
Experience the reliability and performance of Grodan ParGro Quick Drain Blocks. These blocks have been designed and manufactured with the utmost precision and attention to detail, allowing you to achieve exceptional results in your hydroponic or soilless growing system. Benefit from the driest value-priced Rockwool on the market and witness the difference in your plant's growth and overall productivity.
