Light Dep Blackout Film - 6 mil - UV Protected - 40 x 100 ft

Block Light for Controlled Flowering Cycles - 40 x 100 ft Roll

Controlling day length in a greenhouse means keeping outside light out on schedule. This film does that with a solid black side that blocks light and an ultra-white side that faces outward. It is 6 mil polyethylene with ultraviolet protection, so it is built to hold up to sun and weather through the season.

At 40 x 100 ft, this roll suits growers covering a full greenhouse bay or several smaller structures. It is a practical choice for commercial operations and for serious home growers with a large structure.

Frequently Asked Questions

A: The film has one black side and one white side. Growers typically place the white side outward and the black side inward. Confirm the layout against your own structure and goals.
