A layer of water droplets often sticks to the plastic film inside greenhouses, which can reduce light transmission by 20% to 30%. This significantly affects the quality and growth of horticultural crops. As the seasons change, condensation on the greenhouse film becomes a major challenge for growers. The buildup of moisture not only reduces light but also increases the risk of plant diseases. So, how can we effectively remove or prevent these water droplets from forming?
One simple and natural solution involves using soybeans. Start by grinding soybeans into a fine powder. For every square meter of the greenhouse, mix 7.5g to 10g of soy flour with 150g of water. Let the mixture soak for about two hours, then strain it through a fine cloth to remove any residue. Once ready, use a sprayer to apply this solution evenly onto the plastic film. This method helps the water droplets slide off more easily and keeps the surface free of condensation for up to 15 to 20 days. It’s an eco-friendly and cost-effective way to maintain better lighting conditions in your greenhouse.
