Frequently Asked Questions
Will a clear 10mil tarp let enough light through for plants?
Yes — clear 10mil woven polyethylene tarps generally transmit ample visible light for late-season growth while blocking a portion of UV. They’re a common, practical choice for keeping frost off plants and warming a small greenhouse without severely restricting photosynthesis.
How do I attach the tarp without tearing grommets?
Use bungee cords, tarp clips or straps that distribute load rather than thin rope pulled tight through a single grommet. Reinforce stress points with extra rope or a webbing strip under the hem and avoid over-tightening; allow slight give so wind gusts don’t concentrate force on one anchor point.
How long will a 10mil tarp last outdoors?
Lifespan depends on exposure, installation quality and weather. With careful installation, regular checks of seams and grommets, and taking them down during prolonged harsh weather, a 10mil tarp can last multiple seasons. Constant UV and wind exposure will shorten life, so expect more frequent replacement in harsh climates.
