FP 12+ Technology: Extended Lifespan

The FP 12+ film makes a big difference in lifespan:

12+ Months Stability

Maintains structure and properties for at least 12 months

Fungal Protection

Reduces degradation from fungal growth

Structure Retention

No crumbling or deterioration

Consistent Quality

Properties remain constant during cultivation

Factors Affecting Lifespan

💧
Water Quality
High EC/pH can accelerate degradation
🌡️
Temperature
High temperatures (>30°C) shorten lifespan
🦠
Microbial Activity
Fungi and algae can cause degradation
☀️
UV Exposure
Direct sunlight can damage material
🧪
Chemicals
Aggressive agents can damage structure

Reusing Rockwool

Rockwool can be reused under the right conditions:

  1. 1Remove old roots and plant residues
  2. 2Sterilize with steam or chemical treatment
  3. 3Rinse thoroughly with clean water
  4. 4Re-buffer to correct pH
  5. 5Check for structural damage
  6. 6Use only for non-sensitive crops

⚠️ Single use is recommended for propagation for optimal hygiene.

Maintenance Tips for Extended Lifespan

✓ Use clean water with correct pH (5.5-6.5)
✓ Prevent algae growth with light-blocking cover
✓ Regular EC monitoring and flushing
✓ Good drainage for oxygen supply
✓ Protect from direct sunlight
✓ Optimal temperature (18-24°C)
✓ Preventive fungal treatment
✓ Regular visual inspection

Responsible Disposal After Use
