Product Description

The manufacturer has many years of experience developing Rockwool products in the Netherlands and is preferred by some of the largest industrial propagators in the world. The quality of their newest Rockwool cubes, plugs, and starter sheets is by far the best on the market with superb air to water ratio and a fiber structure that holds water longer and has less resistance for the roots to grow in, resulting in stronger roots. Rockwool also encourages faster initial rooting and its firmness is guaranteed. Blocks measure 1.5” x 1.5” x 1.5”

Not what I was expecting
Typically what you get when you buy rock wool is a sheet or two in shrink plastic. Instead, I got some loose rock wool scraps. This doesn’t look anything like the picture and I’m honestly not comfortable using this product in a food application.
