I thought I had it figured out, but now I feel like I am lost again lol. I am trying to avoid a big electric bill from the lighting, so I am re-thinking my choice of doing T5 and now I am looking into LED lighting. Has anyone done this on a standard 55? Or does anyone have any ideas to save $$$ long term from this? I prefer to go high tech. I will do CO2, and I was already figuring on spending 200+ on the light. I want something adjustable if possible, so that I have a big choice from low-high light plants. Thanks!
