Grodan Pargro QD Wrapped Block, 4" x 4" x 4" - Case of 72

Pargro Quick Drain Stonewool

Grodan 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.

What is Rockwool?

Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.

Benefits

• Better grooves, better drainage, less risk of root rot.
• Uniform fiber structure ensures optimum nutrient and pH control.
• Produced at the Grodan factory, but is a little firmer than Grodan.
• Used worldwide by commercial growers for over 14 years.

Why did the GRODAN company create Pargro Quick Drain?

We made Pargro because we recognized the need for an affordably priced, quality rockwool with rapid drainage. There are lower-priced brands in the market that do not live up to what they promise. Most claim a uniform product that drains well but does not fall apart but Pargro QD delivers. Give us a try and you will see the difference.

What is the difference between Pargro and GRODAN?

• Pargro uses only one basic type of wool for propagation, one for blocks and another type for slabs.
• The wool used in GRODAN is configured specifically with Delta® Technology for each GRODAN product that is made.
• The GRODAN line includes a larger variety of products and sizes.
• Pargro marketing and product support is limited, unlike GRODAN.
