Rockwool Lifespan
How long does rockwool last? An important question for professional growers who want to maximize their investment.
Quick Answers
📅
Standard rockwool
6-12 months
⭐
FP 12+ rockwool
12+ months
🌱
For propagation
1 growing cycle
♻️
When reused
2-3 cycles
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:
- 1Remove old roots and plant residues
- 2Sterilize with steam or chemical treatment
- 3Rinse thoroughly with clean water
- 4Re-buffer to correct pH
- 5Check for structural damage
- 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
♻️ Recycling
Rockwool can be recycled into new material
♻️ Reuse
Suitable for less critical applications
♻️ Composting
Only for untreated rockwool
♻️ Waste Processing
Via certified waste processor
