CEA is the practice of growing plants under fully controlled conditions inside buildings.

Unlike greenhouse growing, which relies on sunlight, CEA uses full-spectrum LED lighting to provide different wavelengths specific to each different crop and growth stage. Nutrients, water, temperature, humidity and acidity are also all carefully calibrated to optimise growth.

Crops grow all year round in sheltered mini-ecosystems, with UV lighting to remove bacteria and no risk of contamination by pests and diseases. This means there is no need for harsh chemical pesticides or herbicides.

CEA growing usually produces stronger, healthier crops at a much faster rate than conventional farming methods. It also offers tangible solutions to the many threats posed to the natural environment by conventional agriculture practices.
