Quick Answer
Collecting dew late morning may result in reduced water collection due to increased evaporation rates as the sun rises. However, the exact impact depends on the ambient temperature and humidity levels. Generally, the best time to collect dew is during the early morning hours when the air is cooler.
When to Collect Dew
Collecting dew late morning is still possible, but the process requires careful consideration of the environment. The optimal time for dew collection is typically between 2 and 6 am, when the air temperature is around 40°F (4°C) and the relative humidity is above 80%. At this time, the plants release moisture into the air, forming dew droplets on the surface. If collecting late morning, aim for temperatures below 60°F (15°C) and relative humidity above 60%.
Techniques for Collecting Dew Late Morning
To collect dew effectively late in the morning, use a variety of techniques to minimize evaporation. One approach is to place a clear plastic sheet or tarp on the ground, weighing down the edges with rocks. As the dew forms, it will condense on the underside of the plastic, allowing you to collect the water by tilting the sheet or by using a siphon to extract the water. Another technique is to use a mesh cloth or a mesh bag, which allows the dew to collect while keeping insects and debris out. The mesh can be hung from a tree branch or a fence post, with the mesh facing downward to collect the dew.
