In the summer, high light intensity is a major concern for growing vegetables. Whether it's solanaceous crops like tomatoes or peppers, or melon vegetables such as cucumbers and watermelons, excessive sunlight can exceed their physiological limits, leading to various physiological disorders. These issues often result in lower yields and poor quality. To address this, shade nets have become widely used in summer vegetable farming, offering effective cooling. However, in some cases, the heat inside greenhouses remains difficult to control. Additionally, the built-in shade nets may restrict farm operations due to limitations in the structure of the greenhouse. They also come with drawbacks like high costs and complicated installation.
Now, there’s a simple and practical alternative that vegetable farmers can easily try. Instead of using traditional shade nets, they can apply a mixture of sandy soil or sandy loam, mixed with water to create a diluted mud-like consistency. Using a tool or even by hand, the mixture can be evenly sprayed onto the roof of the greenhouse during sunny mornings or afternoons. The area covered should match the original shade net's coverage. This method provides a similar shading effect as the shade net but without any cost and is very easy to implement. The only downside is that the coating needs to be reapplied after heavy rain. Despite this, it’s a cost-effective and user-friendly solution that offers great value for small-scale farmers looking for an affordable way to manage sunlight exposure during the hot summer months.
