Misk your big problem is the halogen. TAKE IT DOWN. It is no good for growing it has the wrong sepctrum of light. You want metal halide for vegatation or high pressure sodium for flowering. I think you can make the whole grow with the HPS light. Gnatrol ar neem oil are what you want for bugs, I don't have to use any yet but that is what everyone uses. Do a search on bugs to find out more. Hope this helps. G,Day mate
