Seawater Greenhouse technology enables high-yield, restorative agriculture in the world's hottest and driest coastal environments by utilising the cooling power of seawater.

The problem in most hot and arid regions is that plant transpiration exceeds precipitation severalfold. By using water vapour generated by evaporating seawater and providing a protected environment for crops to grow, a Seawater Greenhouse is able reduce transpiration by up to 90% and offer ideal growing conditions for horticultural crops. An additional benefit is that boosted humidity extends beyond the greenhouse and creates an oasis effect that allows heartier perennial crops to thrive outside the protected environment.

Climate modeling allows us optimize greenhouse design to maximize the cooling effect of seawater evaporation.

The Business

Seawater Greenhouse is an expert in tailor-making greenhouse solution to hot and dry coastal regions where agriculture is otherwise impossible. Using our in-house greenhouse modeling software, we can optimize a greenhouse design to maximize the cooling and humidifying benefits of seawater evaporative cooling. Together with clients and partners, we then custom-design the particular Seawater Greenhouse solution to fit both the socio-economic and climate conditions of the particular region.
