harshbucket, read the beginning of the thread. there are links i posted earlier i think.
Scranny420 even knowing all the factors im not going to be able to tell you what i think your yield will be. read up on what people yield per sq ft with a given wattage. im not fully fo shures, just try something and record what happens and how much you yield. try something different on multiple plants at the same time (different nutes, different flower and veg times, different watering times) with enough plants you could make some general observations and use other factors such as temperature, distance of light to canopy, humidity later on to learn even more. i think you could swing 16 plants. just let yield be yield and learn from it. if you want to make some serious money with this stuff your going to need more lights. btw, im not too familiar with hydroponics read alot on it but never experienced it first handed.
