Locating Light Leaks Many indoor growers don’t know that their rooms have light leaks until it is too late, and the problem expresses itself by way of hermaphrodites and seeded flowers. As a result, it’s a good idea for cultivators to regularly check their growrooms to make sure they are 100 per cent dark during the nighttime period. To inspect an indoor garden for light leaks, it’s best to enter the grow with a green light when the primary lights are off. Once situated in the garden, turn off the green light and sit still for a while to let your eyes adjust to the blackness. At this point, it should be easy to canvass the walls and ceilings of the room and discern any potential points of light leak trouble. Also, this inspection process should be done during various parts of the day, as different angles of sunlight outside can cause light leaks during isolated time frames. Gardeners should also be advised that control panels on grow equipment, such as atmospheric controllers and AC units, often give off light. This light is usually red or green and is residual from the digital readout. As such, it is recommended that growers cover up these light sources with electrical tape or some sort of removable opaque material. “Most crops PERFORM BEST IN STABLE ENVIRONMENTS.” Compared to any other form of controlled environment agriculture, sealed-room growing provides the most mastery over environmental factors. However, these growrooms present novel challenges of their own, as seen with the issues surrounding light leaks. For the conscientious gardener, regular inspections of one’s garden should alleviate any light leak problems. All things considered, this knowledge will provide a better platform for troubleshooting on the macro- level moving forward. Maximum Yield 53
