Now that I determined that I have about 6 hours of sunlight I would like to increase the amount with reflective light. My sfg space in within a space that is made up of railroad ties that bring the space up off the original yard. The north side of the sfg comes up to the railroad ties so I have a large maybe 8" tie that I can use to place something that can reflect the sun from that side. I would like some thoughts of what some of you think would be a good material to use and if you think I am only spinning my wheels. I will try and give you a pic of the garden if I can figure it out. I guess I also need help in sending a pic.
