Red Mulch Film Sheets (3′ X 3′)

3 foot by 3 foot sheets, 8 per package. Boost tomato crops 10 to 20 percent with this bright red, thin plastic film. Like black mulch, it warms the soil, retains moisture, deters pests and controls weeds, but the red film also reflects far-red wavelengths up into the plant, stimulating development. Results are earlier and increased yields. Not recommended for use in warmer southern states.
