Ok this is going to be a basic setup and a review of the mars hydro sp150. I no it's discontinued but I was sponsored this light a few years ago before my brake on growing. So I want to keep my word. Also I'm growing in a 2x1.5 ft spot in closet. Freebie from mephisto. Some old kings mix soil and gaia green I had sitting around. I pre amended soil 3 tbls a gallon since it contains very little nutrients with 10 percent worm casting in a 2 gallon pot.
