Developed by Prof. Brent Loy of the Univ. of New Hampshire. Transmits near-infrared radiation to increase soil temperatures up to 8–10°F, while blocking the PAR (photosynthetic active radiation) responsible for vigorous weed growth. Perfect for heat-loving crops like melons and other cucurbits. Apply film soon after bed preparation for maximum weed suppression. 1.0 mil. embossed material is suitable for mechanical mulch layers.
