- Is clear PVC better than a blue poly tarp for a greenhouse?
- Yes, if you need light. Clear PVC transmits daylight while blocking rain, which poly tarps cannot do. Poly tarps are lighter and cheaper to replace, but they block light completely.
- Will it hold up outdoors through winter?
- PVC vinyl handles rain and snow well and resists rot. Cold makes it stiff and brittle, though, so avoid sharp folds and tie it down loosely enough to flex.
- Does it let heat escape or trap it?
- It traps heat like a greenhouse panel, which helps in cool weather. In summer sun, an enclosed space behind it can get very hot, so plan for ventilation.
- How do I stop condensation under it?
- You cannot fully. PVC does not breathe, so leave gaps or vents at the edges and avoid sealing it tight against surfaces that sweat.
- Can I cut it to size?
- Yes. PVC vinyl can be cut with heavy shears or a utility knife. Cut inside the hemmed edge if you want to keep the reinforced grommet strip intact.
- What is included with the tarp?
- The tarp itself. Grommets are set along the edges for rope or bungee tie-downs; rope, bungees and fasteners are not included.
- Where is the Clear 8' x 20' PVC Vinyl Heavy Duty Waterproof Tarp cheapest?
- At Walmart, for $182.31, as of our latest check.
