Our CEA Farm

Stover Shop Greenhouses is a USDA GAP (Good Agriculture Practices) certified CEA (Controlled Environment Agriculture) farm.

CEA is a technology-based approach towards food production. The aim of CEA is to provide crop protection and maintain optimal growing conditions throughout the development of the crop. Production takes place in an enclosed growing structure, such as greenhouses, and plants are grown using hydroponic methods in order to supply the proper corrected amount of water and nutrients to the root zone. CEA optimizes the use of resources such as water, energy, space, capital and labor.

Controlled variables include: 

  • Temperature (Air, nutrient solution, root zone)
  • Humidity (%RH)
  • Carbon Dioxide levels (CO₂)
  • Light (Intensity, spectrum, interval)
  • Nutrient concentration (PPM, EG)
  • Nutrient pH (Acidity)


Less water needed


Less fertilizer used

Grow year-round

Happier planet

Through our vertical growing practices, we are able to grow and harvest thousands of heads of lettuce per week on a substantially smaller footprint. Through technology, today’s growers can produce more by using less.

Less land by growing vertically

 Less water and nutrients by using an Automated Fertigation Controls

 Less stress on plants by using computer controlled environmental curtains and evaporative cooling pads for optimal growing conditions

Less labor by automating as much of the process as technology allows
