Rock wool blocks provide the space and uniform water and nutrient distribution they need to continue thriving in their second stage of life.
Rock wool blocks are intelligently designed to deliver healthy, even root zones and consistent crop performance. Mineral wool growing media helps to give more steerability to the grower and eliminates the messy, time-consuming processes of other growing media, like filling pots and mixing materials.
Key Points of Rock wool blocks
Rapid rooting into plug
Supports Healthy Root Growth
Great for transplanting
Fiber structure with a lower density and no loss of firmness
Vertical fiber structure
How to use Rock wool Blocks
Soak in pH-adjusted water (5.5–6.0) for at least 30 minutes.
Place seedling or starter cube into the hole in the block.
Place block in tray, hydro system, or on a slab.
Ensure proper drainage and avoid waterlogging.
