Cultilene Rockwool Block

Cultilene Blocks have an optimum air/water ratio for healthy root growth and allow for great continued rooting thanks to the extremely even distribution of water and EC. These blocks have an excellent water absorption and (re)saturation rate and feature the exclusive Plant Comfort fiber structure which has a lower density of resistance during rooting with no loss of firmness.

All blocks except the 3x3x3 also have the Optiplus feature, which is a unique design on the underside of the block allowing for excess water to drain away easily.


Ask a Question
  • I’m new at this. When your produce start sprouting do you put the block in the pot or do I have to remove it.

    Good question, leave it in the block, the roots will continue to grow out of the block and into the surrounding soil or other growing medium.
