Buying Guide: Key Purchase Considerations
- Thickness and durability: Choose 4–6 mil for typical gardens; 10 mil is better for high-traffic or long-term moisture barriers.
- UV resistance: If the sheet will stay outdoors year-round, look for UV protection to extend life.
- Size and coverage: Match sheet dimensions to bed size; longer rolls reduce seams but may be harder to maneuver.
- Weed suppression strength: Dark, opaque films maximize weed growth suppression by blocking light.
- Moisture control: Consider vapor barrier properties if you need soil or ground moisture management.
- Ease of handling: Lighter thickness sheets are easier to cut and lay; thicker sheets resist tearing but require more effort to handle.
- Cost vs. coverage: Compare price per square foot to select the most economical option for your project scale.
