As I have been researching and reading some threads here, I have been thinking bout the first light I bought, my sf4000 450 watt spider farmer light and when I got it I thought this will do for the moment and down the track I'll get something else, as I had gone the spider farmer tent and exh fan as well. In the near future was considering to leave the spider farm just as a veg tent and get a better set up for flower, and staying with LED. Maybe a gorilla 5x5 tent, I get want to get a better quality light for it. When I got the sf4000 I hadn't researched enough, and I want to get some feedback about what I should be looking for as far as quality and efficiency, and will work in a 5x5 area. I also had some concerns about the quality of the spider farmer light after reading a post about fire concern
