I found one of those car dashboard-sunlight reflectors that I am going to stand up around the plant and have the lights hanging down, hopefully within a few inches of the plant. Will it be okay to not have any type of reflector directly vertical of the plant, as the lights will be hanging from above with the reflectiveness all around the sides, with the reflector definitely a foot or so taller than the top of the plant. thnx in advance. peace
