Featuring a 6 mil polyethylene construction this 15 by 40 ft greenhouse film keeps plants warm across a full growing bed. The 0.15 mm gauge resists tears from wind branches and frame edges while Uv inhibitors prevent degradation through season after season. Light transmission stays high so seedlings vegetables and flowers receive diffused glow for steady photosynthesis while heat is trapped to extend spring and fall growing windows. The oversized panel drapes over hoop houses and cold frames.
