One point five inch rockwool cubes

This set consists of 196 rockwool cubes, each measuring 1.5 inches. This slightly larger size provides more room for root development compared to standard 1 inch plugs. The cubes come in a sheet format, which makes it easier to organize and water a large number of seedlings at once.

The 1.5 inch dimension is a common standard for many commercial hydroponic systems, allowing these cubes to fit into many pre-made grow holes. The rockwool fibers are oriented to encourage downward root growth, which helps plants establish themselves more quickly after they are moved to their final location.

These listings are suitable for growers who want a more substantial starting medium for larger seeds or more vigorous cuttings. The material is durable enough to hold its shape throughout the propagation phase. It is an effective choice for those looking to maintain a clean and efficient indoor garden environment.
