is the #1 requested light deprivation greenhouse cover in the nation because it is light blocking, with no pinholes or perforations! Our black out light deprivation tarp is an 8 mil Black/White string reinforced polyethylene film manufactured with a mix of virgin polyethylene resins. The white outer layer contains UV inhibitors and thermal stabilizers to reduce heat build-up as well as condensation and the black outer layer contains carbon black to enhance outdoor life and ensure total light deprivation.
BOLD® Black Out Light Deprivation greenhouse tarp is strong and durable because it consists of two sheets of high strength virgin polyethylene film laminated together with a third layer of molten polyethylene. A heavy scrim reinforcement placed between these plies greatly enhances tear resistance and increases service life. The diamond reinforcement instantly responds to rips and tears by surrounding and stopping it.
