Precision horticultural climate engineering parameters, solar Daily Light Integral (DLI) curves, seasonal thermal screen deployment strategy, and heating/cooling load calculations for Lake Naivasha (Rift Valley), Kenya (Highland Equatorial (Cfb, 1,900m)).
In Lake Naivasha (Rift Valley), Kenya, natural solar Daily Light Integral transitions from 38-44 (12h Day) mol/m²/day during winter solstice to 38-44 (12h Day) mol/m²/day at summer peak. For commercial crops like World's Top Cut Rose & St. John's Wort Export, target canopy DLI requires dynamic screen management to avoid photoinhibition during midday radiation spikes exceeding 850 W/m².
Screen Specification: Night Thermal Screen Heated by Direct Geothermal Brine
Primary Cooling Strategy: Passive High-Eave Sawtooth Ventilation
Maintaining positive day-night temperature differential (DIF) and nighttime dehumidification minimizes condensation on cold structural glass surfaces, suppressing Botrytis and powdery mildew spore viability.
Major protected cropping varieties grown at scale in this regional cluster: World's Top Cut Rose & St. John's Wort Export.
