Why choose rock wool blocks?
- Great Water Retention
- Good Air Permeability
- High Germination Rate
Specification:
- Seedling block has good characteristics of air permeability, water permeability and root penetration.
- Once the seedlings are in the soil, the callus in contact with the soil will immediately absorb water and grow a lot of new roots.
- Widely used for planting and seedling raising, group breeding, cutting seedling raising of fruits, vegetables, flowers, and other crops.
- The bred seedlings have no rolling roots, no slow seedling period, high survival rate, good quality, and strong stress resistance, which greatly improves work efficiency.
- Size: 25*25*40mm
Package List:
8 Sheets seedling rockwool cubes(400pieces mini rockwool blocks in total)
How to Use
- 1. Please cut the rock wool into cubes according to your own needs with a knife before soaking.
- 2. Then adjust the water temperature to 30-35 ?, the EC of the nutrient solution to 1.5-2.0ms, the PH to 5.0-5.5, and thoroughly soak the rockwool cube with the nutrient solution. Use pH paper to make sure that its pH is in the desired range for your seeds. The optimum pH for most plant seeds is around 5.5.. Don't squeeze it!
- 3. Control the suitable moisture, illumination and temperature to improve the germination rate of seeds.
- 4. When the robust roots penetrate through the rock wool about 0.5-1 inches, transplant it into a suitable container.
