The most popular rockwool (aka stone wool) for indoor growing, hydroponics and greenhouse speciality crops! Grodan GRO-BLOCK Improved, with Advanced Wetting Technology, has the optimal fiber structure and physical properties needed to grow more uniform and high-quality crops while using less water and nutrients.
Developed specifically for seed and cutting propagation, the Improved MINI-BLOCKS, 2″ allow for even water distribution throughout the height of the substrate which is the basis for a robust root system with greater capacities for water and nutrient uptake. Indoor growers will experience improved plant growth, including larger plant size, greater stem thickness, and bigger fruits and flowers.
Benefits:
• Even water distribution maximizes plant growth and development
• Rooting occurs several days faster, speeding up the time to harvest
• Ideal aeration at the root zone — prevents overwatering and root suffocation
• Contains no weed seeds, disease pathogens or insect pests
