A plastic light diffuser sheet, like the IRAC 6‑mil greenhouse film from GreenHouseFilm, is hugely beneficial because it spreads light evenly across your plants — the film offers 55% light diffusion, ensuring there are no harsh hot spots. This even light distribution promotes balanced growth by helping all parts of the plant get sufficient sunlight. The IRAC film also contains infrared additives to retain heat at night, and anti‑drip technology to minimize condensation. Plus, being a heavy-duty, UV-stabilized 6‑mil sheet, it’s durable and built to last for up to four years.
