What fabric weight floating row cover is needed to protect tomato plants from a 32°F frost?
To protect tomato plants from a 32°F frost, agricultural producers must deploy a 0.9 to 1.2 ounce-per-yard thermal weight fabric. This specification yields a 4°F to 6°F temperature differential, ensuring the sub-canopy temperature remains above the critical 33°F threshold. Spunbond polypropylene constructions at this density maintain a mandatory 30% to 50% photosynthetically active radiation (PAR) transmission.Thermodynamics of Plant Tissue ProtectionTomatoes (Solanum lycopersicum) suffer catastPosted : 11:47 am.today | 0 views
