Frequently Asked Questions
Are these clear tarps breathable enough for seedlings?
The 20 mil PVC vinyl tarps are not inherently breathable. They transmit light well and keep out rain, but you should plan for ventilation (roll-up sides, vents, or timed openings) to prevent overheating and condensation around seedlings.
How do I handle wrinkles and creases after unpacking?
Wrinkles are common from folding in shipping. Lay the tarp flat in the sun for a few hours or gently warm with low heat while stretching and fastening at the grommets to help relax creases. Over time exposure and tension will smooth the surface.
What installation features matter most for greenhouse use?
Look for reinforced edges and rustproof grommets spaced for secure fastening, plus generous dimensions that reduce seams. These features make it easier to tension the tarp, limit flapping in wind, and create roll-up or venting sections for airflow.
