So lumens and light close to plants is very important. The amount of lumens decreases greatly within a short distance from growing plants thus the closer to them the better. That said and aggreed upon, how much can that same growing light really affect hanging cureing plants that are lets say 8 to 12 feet away from them and not at all in a direct path as with the plants that are having the light directed at them for growing. In other words how much degradation in a quality bud will you really get if the hanging plants are not in complete darkness??
