Frequently Asked Questions
How much light do translucent vinyl tarps let through?
Clear PVC/vinyl tarps transmit a high percentage of visible light, often comparable to single-pane acrylic. Look for products described as 'transparent' or 'clear' — these maximize photosynthetic light for seedlings. Thicker tarps may diffuse slightly more light but generally still allow enough for seed starting.
What mil rating is best for a greenhouse tarp?
For seasonal seed-starting and temporary cold frames, 12–15 mil is usually sufficient. For year-round greenhouse walls, heavy weather or large spans, choose 18–20 mil for better durability, less sagging, and improved resistance to wind and snow.
How do I avoid wrinkles and creases when installing a clear tarp?
Unpack and lay the tarp flat in sun or a warm room for a few hours to relax creases. Pull it taut when installing and use frequent tie points (grommets every 20–30 in) so the material sits tight. Heavier 20 mil tarps will settle flatter over time than very thin sheets.
