FAQ
Q1: How do you prepare Rockwool Growth Matrix cubes for planting?
A: Begin by soaking the cubes in water with a pH of 5.5–6.0 for 20–30 minutes. Allow them to drain until moist but not dripping. Insert seeds or cuttings into the pre-drilled holes and place the cubes into trays or systems. Maintain steady moisture with proper irrigation. This ensures balanced conditions for germination and root establishment.
Q2: How do you prepare Rockwool Growth Matrix cubes for planting if using them for hydroponics?
A: For hydroponic systems, it is critical to pre-soak the cubes with water that matches the nutrient solution pH. After draining, position the cubes directly on the hydroponic setup such as NFT channels or slabs. Ensure nutrient-rich water flows consistently around the cube without causing saturation. Following these steps helps achieve uniform root penetration and healthier plant growth.
