Rockwool Blocks White Label

These culture blocks measuring 4x4x4 cm are ideal for plants that have a short lifespan of less than 6 months. These blocks are particularly suitable for cultivation on rockwool mats or in an NFT irrigation system with a root fleece.

Stone wool or mineral wool is a hydro substrate that does not contain soil or other organic substances. Rockwool is very absorbent because you can fertilize it in a targeted manner and add as much water as your plants need at the moment.
