Cultiwool Block 6"x 6"x 4" (64/Case)

The Cultiwool Block 6"x 6"x 4" is a professional-grade stone wool growing block designed for hydroponic, greenhouse, and soilless cultivation. Its larger format provides generous rooting volume while maintaining an effective balance between water retention and aeration, helping growers create a consistent root-zone environment throughout the crop cycle. The 6"x 6"x 4" format contains 64 blocks per case.

Designed for transplanting established seedlings, rooted plugs, cuttings, and clones, these Cultiwool blocks provide developing plants with additional space for vigorous root expansion. Their uniform fibre structure helps promote consistent moisture distribution while allowing oxygen to remain available within the root zone.

Excellent Air-to-Water Balance

Cultiwool stone wool features a specialized fibre structure designed to provide a strong air-to-water ratio while retaining moisture efficiently. This makes it easier to manage irrigation schedules and nutrient delivery while supporting healthy root development in hydroponic and controlled-environment growing systems.

Larger Rooting Volume

Measuring approximately 6"x 6"x 4" (15 x 15 x 9.8 cm), each block provides substantially more rooting space than smaller propagation blocks. This makes the format especially useful as plants progress beyond the early propagation stage and require greater root-zone capacity.

Improved Drainage

Cultiwool growing blocks feature drainage grooves on the bottom to improve water movement beneath the block and reduce direct contact with cultivation tables or other growing surfaces. This design supports more effective drainage and better moisture management.
