Eggplants thrive under warm microclimates and high solar radiation, featuring extensive leaf areas that transpire heavily. Maintaining sufficient root-zone temperature (≥19°C) and tight biological control against spider mites and thrips ensures continuous fruit setting without blossom drops.
Maintaining a DIF of +4 to +6°C (Day Temperature minus Night Temperature) regulates internode length and crop balance. When vegetative vigor is excessive, reducing DIF steers the plant toward reproductive flowering; increasing DIF restores leaf expansion and canopy Light Extinction (Beer-Lambert k-factor).
Target root-zone drain fraction: 25 - 35% to avoid substrate EC accumulation and root hypoxia.
Primary Pathological Risks: Two-spotted Spider Mite (Tetranychus urticae), Verticillium Wilt, Thrips, Low Light Fruit Deformity.
Biological Predator Sizing & Release Strategy: Phytoseiulus persimilis (3–6 mites/m²), Amblyseius swirskii, Macrolophus pygmaeus.

Eggplant root systems are highly sensitive to cold substrates. Keep rockwool/cocopeat slab temperatures at 19–22°C. Below 16°C, phosphorus and water uptake plummet, causing stunting and flower abortion.
