I got 1 of each a few weeks ago for free and I might be getting 1 more mh and 1 more hps. I am currently only growing 1 plant and I have 28,000 more lumens from cfls. the MH lumens is about 6500 and the hps is 4000. how much of a difference will the HID lighting make? my plant is 2 feet tall, but I am growing vertically
