Pros:
1. The V-shape design of the starter plug discourages the tangling of roots, and easy to separate the plug and transplant.2. The shape and firmness of the rock wool plugs are of a quality that makes processing significantly easier, whether that processing is mechanical or manual.
3. Can be used without a seedling tray or fits a standard 10 X 20 tray (flat).
4. Does not contains any pathogenic bacteria, which can reduce the risk of virus infection in seedlings.
5. It ensures optimal growth conditions for roots growing, and cooperating with reasonable irrigation strategies can improve the quality of seedlings.
6. Stable pH and EC can reduce the risk of propagation and increase the germination rate of seeds.
7. The substrate is produced automatically and uniformly with consistent performance, which can unify the ratio of water to fertilizer and water vapour, achieve precise control, and save cutting propagation management
costs.
8. No scattering phenomenon (No slaking), which saves cleaning costs.
9. Work with bigger hole-diameter UPuper® CB series growing cubes, and put them inside the hole of this.
10. A tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth.
11.Can also be transplanted into more traditional planters and growing mediums.
