Troubleshooting light leaks in a greenhouse requires a systematic approach to identify and rectify any gaps or weaknesses in the covering. Begin by conducting a thorough inspection of the entire greenhouse structure, focusing on seams, edges, and any areas where the blackout materials meet the frame. Use a flashlight at night to highlight any light leaks, making them easier to spot.
Once identified, seal any leaks using high-quality light-blocking tape or specialized adhesives designed for greenhouse materials. If the covering is worn or damaged, consider replacing it with new blackout materials to ensure complete opacity.
