- Can I use it as a greenhouse cover?
- Yes, for light-duty use. It passes daylight and blocks rain, but it is not breathable, so open the sides for airflow or condensation will collect. It is thinner protection than twin-wall polycarbonate.
- Will it stay clear outdoors?
- Clear PVC holds up for a season or two but gradually yellows and stiffens in strong sun. Store it out of direct sun when not in use to slow that down.
- How do I secure it?
- Use the grommets with rope, bungee cords or zip ties. Add a batten or extra ties along the middle on windy sites, since the grommets are the weakest point.
- Is it thick enough to block wind?
- It blocks wind and rain, but it is a flexible sheet, not rigid glass or acrylic. It will flap in gusts unless pulled tight on a frame.
- Can it go over plants directly?
- Better on a frame above the plants. Laid directly on leaves it traps moisture and can scorch foliage in sun.
- Where is the Clear Vinyl Tarp 7x10 ft with Grommets cheapest?
- At Walmart, for $73.40, as of our latest check.
