Buying Guide: Key considerations for plastic row covers
Choosing the right plastic row covers depends on climate, crop type, and garden layout. Notable factors include:
- Size and coverage: Larger spans reduce the need for frequent adjustments but may require hoops or stakes for support. Check if your beds fit common dimensions (e.g., 10 x 20 ft or 12 x 25 ft).
- Material and density: Higher-density polyethylene offers better heat retention and durability, while lighter fabrics provide more airflow for delicate transplants.
- Light transmission: Some frost blankets block significant light, while others offer 70–85% transmission. For leafy greens, consistent light is important; for fruiting crops, a balance helps.
- Ventilation and humidity: Breathable fabrics reduce mold risk. Look for fabrics that maintain air exchange without sacrificing warmth.
- Durability and weather resistance: UV stabilization, tear resistance, and wind tolerance determine season-long performance in varied climates.
- Accessories: Clips, stakes, hoops, and ground stakes add installation ease and provide a sturdy frame. Kits with hoops simplify setup for winter protection.
- Reusability and storage: Foldable or roll-up designs save space and extend product life across seasons.
- Replacement parts and repairability: Availability of replacement clips or hoops is helpful for long-term use.
Overall, for colder American regions, larger kits with included hoops and sturdy poly fabric tend to offer the best balance of protection and ease of setup. If you prioritize sunlight, select clear or semi-clear films with high light transmission. For maximum frost protection, thicker or higher-density fabrics paired with a frame system are advantageous.
