Blanket protection for your seedlings from the damaging effects of heat and sun! Tested and approved by reforestation biologists, silviculturists, and tree planting contractors, the “Heat Shield” Tarp is your best insurance for seedling survival. The Terra Tech “Heat Shield” Tarp is made from a durable, white vinyl fabric that is coated on one side with a special highly reflective metallic finish. Placed over the seedling bags with the white side up and metallic side down, the “Heat Shield” will effectively protect your seedlings during lifting, en route to packing, and at the planting site. Do not use as a pickup cover-prolonged flapping at highway speeds will cause the laminated surfaces to separate. Made in the U.S.A.
