UV-treated greenhouse plastic film have the ability to manipulate the transmission of particular sun wavelengths to boost plant growth. Manufactures have worked hard to provide a material that will give good service, high light transmission and properties that improve plant production.

Moreover, it is highly resistant to high heats and low temperatures. Youd be surprised how effective plastic films are in terms of extending the growing season! If youre considering a greenhouse, you may be wondering whether a plastic one is a good option. Thickness can range from 10mm to 20mm and how many layers of it will be used (commonly twin-wall to tri-wall). Regular greenhouse grade polyethylene film allows 30% to 60% of the IR heat to escape. iPad if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'farmfromhome_com-leader-1','ezslot_7',112,'0','0'])};if(typeof __ez_fad_position!='undefined'){__ez_fad_position('div-gpt-ad-farmfromhome_com-leader-1-0')}; Depending on how much heat you want (for instance, this could be less for those that live in Texas), consider what kind of material you want to build the overall greenhouse with.
