Regardless of lack of light, you need to curtail the watering greatly. Succulents can literally go weeks without water, and if mature, they can go a month. Many succulents will "tell you" when they need water because their fat leaves will begin to shrivel. Is there some place in the nursery that gets more light? If so, perhaps you can talk the owner/manager into letting you move the succulents to that area.
