Grodan Stonewool Mini-blocks

The starter Mini-blocks from Grodan are popular for seed and plant cutting propagation. The fibrous structure of the Starter Mini-blocks creates an ideal air-to-water ratio that encourages robust root development. 

The advantage of Mini-blocks is that they can independently sit in a tray without any support, plus they keep their shape! Each block is wrapped in white plastic on all sides for individual use.

As your plants grow, remove the wrapper and easily transplant into GrowCubes, Hydroton or soil, or transfer to larger stonewool slabs once roots have been established.

Stonewool (rockwool) is recognized the world over as the ideal hydroponics growing substrate. Grodan stonewool is known for its quality, consistency and performance.
