The greenhouses are designed by Penn State HESE.
GRO Greenhouses help foster food security through reductions in water usage and faster growing times, allowing customers to grow produce all year round.
GRO Greenhouses are the collaborative work of World Hope International and the Humanitarian Engineering and Social Entrepreneurship Program at Penn State. They are usable year-round, provide a controlled environment, reduce water consumption, and ensure crop production despite seasonal weather changes. The GRO Greenhouses lead to a 30% reduced growing time, 300% increased yield and 60% reduction in water usage. Locally sourced materials (except the plastic glazing) and simple construction design allow for construction in two days.

The GRO Greenhouse is constructed using wood and plastic glazing as the key materials. The wood is treated before it is used (treating the wood will help prevent pest damage). The dimensions of the GRO Greenhouse are 6m length, 6m width and a height of 3m. However, due to the modularity of the Gro Greenhouse, the addition of supplemental greenhouse sections can be added when the need to increase the food production space arises. Simple construction design allows for construction of the GRO Greenhouse in two days’ time by two carpenters. A construction manual is provided by Gro Greenhouse, thus providing a procedure and best practices for the construction of the greenhouse. The greenhouse comes with an irrigation system that utilizes drip irrigation.
Technical Support is provided by GRO Greenhouse workers/agents.
The materials used in construction are locally available.
The greenhouse has an average lifespan of 5+ years.
The GRO Greenhouses performance targets are: 30% reduced growing time, 300% increased yield, 60% reduction in water usage and 6 months return on investment.
Penn State HESE tested the GRO Greenhouses in Kenya, Tanzania, and Rwanda.
