  • SolaWrap Greenhouse Film vs. 6 Mil Poly: A Breakdown

6 mil greenhouse plastic- Does it Hold Up

Choosing the right greenhouse film can significantly impact your plants' growth and overall success. Here's a comparison of SolaWrap and 6 mil poly to help you decide:


  • SolaWrap: Made from polyethylene plastic with encapsulated air bubbles, creating a thicker and more durable film (usually around 334 mil).
  • 6 Mil Poly: Standard polyethylene plastic film, typically 6 millimeters (mil) thick.


  • SolaWrap:
    • Durability: Significantly more durable than 6 mil poly, lasting for up to 10 years with a UV guarantee. It can withstand heavy snow, wind, and hail.
    • Insulation: The air bubbles act as an insulator, retaining heat better and extending the growing season.
    • Light Transmission: Allows sufficient light for plant growth while offering UV protection.
  • 6 Mil Poly:
    • Affordability: Significantly cheaper than SolaWrap, making it a good option for temporary greenhouses or tight budgets.
    • Lightweight: Easier to handle and install due to its lower weight.
    • Availability: Widely available and readily accessible from various retailers.


  • SolaWrap:
    • Cost: More expensive than 6 mil poly, with a higher initial investment.
    • Weight: Heavier than 6 mil poly, potentially requiring a sturdier greenhouse frame for support.
  • 6 Mil Poly:
    • Durability: Less durable than SolaWrap, prone to tearing, ripping, and needing frequent replacement.
    • Insulation: Offers minimal insulation, potentially limiting your growing season in colder climates.
    • UV Protection: May degrade faster due to sun exposure, potentially requiring more frequent replacement.

Who Should Use Each?

  • SolaWrap: Ideal for serious gardeners, professional growers, or those in regions with harsh weather conditions. The longer lifespan and better insulation justify the higher cost in the long run.
  • 6 Mil Poly: A good option for hobbyists, those with temporary greenhouses, or tight budgets. It's suitable for mild climates where you don't need extended growing seasons or superior insulation.

Additional Considerations:

  • Greenhouse Size: For larger greenhouses, SolaWrap's durability might be more crucial to withstand potential wind and snow loads.
  • Plant Needs: If you're growing heat-loving plants or want to extend your growing season, SolaWrap's insulation benefits might be essential.

Ultimately, the best choice depends on your specific needs, budget, and climate. If you prioritize affordability and ease of use, 6 mil poly might suffice. But for long-term durability, better insulation, and a potentially higher crop yield, SOlaWrap could be a worthwhile investment.
