Well the most expensive piece was the 400 Watt HPS w/Metal Halide Converter Bulb + Timer.. that was $205.00.. so I will estimate below for you

Roughly $420.00- Consider some of this I can use over and over, some of this I could have gottten cheaper, an ounce of weed around my parts is between $100.00 - $150.00, which is usuall crap with a bunch of seeds.. probably 5-6% THC.. all off this is supposed to be 15-20% THC (but I doubt it), so I am gonna say this would sell for $150 an ounce and this is all for my personal use (Perhaps even more, I am not an expert on these things maybe $200.00) so I need 3 ounces to basically get my money back and I am hoping to have 4-5 plants.. Of course I will get clones from this grow and next time I am doing HYDRO.. (If there is a next time I am paranoid)
