Parameter | Ideal Specification | Benefit |
---|---|---|
Thickness | 0.10–0.15mm | Balance of light transmission & durability |
Light Diffusion | 30–50% | Reduces leaf burn, promotes even growth |
UV Stabilization | 3–5 year lifespan | Extended service in high-sun regions |
Anti-Drip Coating | Hydrophilic additive | Prevents disease-causing water droplets |
✔ Temperature Regulation
Day: Maintains 25–30°C via IR-blocking (≤50% IR transmission)
Night: 3–5°C warmer than outdoor (thermal retention)
✔ Humidity Management
Reduces water consumption 30% vs. open-field
Prevents condensation (≥80% anti-fog efficiency)
Vegetable Type | Film Type | Special Feature |
---|---|---|
Leafy greens | Clear film (92% PAR transmittance) | Maximizes photosynthesis |
Tomatoes | Diffused light film | Prevents fruit sunscald |
Cucumbers | Anti-condensation film | Reduces powdery mildew risk |
Peppers | UV-blocking film | Enhances anthocyanin production |
Structure Preparation
Smooth all sharp edges on framework
Install insect nets prior to film
Film Deployment
Stretch to 10–15% tension (prevents wind damage)
Use EVA-backed clamps for secure attachment
Ventilation Design
Roof vents = 15–20% of floor area
Side vents = 1m height for hot air escape
Factor | Greenhouse Film | Glass Greenhouse |
---|---|---|
Initial Cost | $2–5/m² | $50–100/m² |
Energy Savings | 40% less heating | Baseline |
Payback Period | 1–2 seasons | 5–8 years |
Maintenance Tips:
⚠ Monthly cleaning (maintains 95% light transmission)
⚠ Pre-winter inspection (patch holes >3cm diameter)
⚠ Annual UV coating check (use radiometer)
