Greenhouse Film Clear — 4 Mil, 1-Year UV, 90% Light Transmission

The economical way to cover a seasonal tunnel. This 4 mil clear film gives you the same 90% light transmission as our 6 mil films at a lower cost per square foot — the right choice for one-season structures, overwintering covers, caterpillar tunnels and budget builds where a 4-year film would be overkill.

Why growers choose it

• 90% light transmission, 18% diffused — full, even light for seedlings and crops
