Pargro Rockwool Strips | 4in x 4in x 2.6in with Hole - Carton

Shallow-Profile Value-Tier Rockwool Strip for Propagation Rows, 4x4x2.6in

Growers running a high-density propagation row don't always want a premium block engineered for one plant at a time when a lower-profile strip will do the job at a lower price. Grodan's Pargro Rockwool Strips ship dry and value-priced, sized at 4in x 4in x 2.6in with a factory-cut hole already in place, and re-wet quickly once soaked so a row of strips is ready for transplants in one pass.

This carton of 216 strips is sized for restocking a propagation row in a single order rather than buying loose or small-batch quantities.

Key Features & Benefits

• 4in x 4in x 2.6in Shallow Format — a lower-profile strip suited to a tighter footprint than a full-depth block.
• Pre-Cut Hole — ready to receive a rooted plug without an extra on-site cutting step.
• Dry-Shipped, Value-Tier Rockwool — ships dry to keep freight weight and cost down, then re-wets quickly once soaked.
• Carton of 216 — packaged for growers restocking a propagation row in one order.

About Pargro Rockwool

Pargro is Grodan's value-tier stone wool line, sized for a range of growing setups and built to re-saturate quickly after a dry shipping cycle, a different price point from Grodan's premium Improved Gro-Block series.

Frequently Asked Questions

What does 'value-tier' mean for Pargro compared to Grodan's other rockwool lines?

Pargro ships dry rather than pre-moistened, which keeps freight weight and cost lower than a wet-shipped premium block. Growers rehydrate it on-site before transplanting, trading a small prep step for a lower per-unit price.

How do I prepare a Pargro Strip before use?

Soak the strip in pH-adjusted water until it's fully saturated, since it ships dry rather than pre-wetted. Once rehydrated, set a rooted plug into the pre-cut hole and keep the strip consistently moist.

Why choose a shallow 2.6in strip instead of a full-depth block?

A shallow strip suits growers running a high-density propagation row where footprint and re-wetting speed matter more than vertical block depth. Full-depth blocks suit plants that need more root volume before their next transplant.

How many strips come in one carton?

This carton contains 216 strips, sized for restocking a propagation row in a single order. That volume suits commercial propagation operations running through strips on a regular cycle.
