Plants are not People

Controlled environment agriculture (CEA) requires a fundamentally different approach than typical comfort cooling. Plant health, and in turn owner profits, depends on a stable environment that facilitates optimal nutrient uptake through controlled transpiration rates. Effectively managing both sensible and high latent loads to maintain an optimal vapor pressure deficit is essential. Hesnor Engineering Associates (HEA) is experienced with the systems and equipment required for owners to achieve significant returns on their investments.
