There are methods for horticulture producers to boost the efficiency and productivity of low-tech greenhouse systems and unlock new market opportunities.
Low-tech greenhouses are more affordable and based on simple technology. Temperature control and ventilation are crucial to productivity. Saw-tooth multi-span or flat arch structures are used in hot, dry climates.
By covering the ground with a clay loam, overlain with a layer of manure, and capping it with river sand, growers have created an ideal environment for preserving precious water. The clay loam has high water retention properties, and the manure boosts microbial activity. At the same time, the river acts as a mulch. It holds the water within the soil, reducing evaporation and unwanted humidity.
