Average about 600g wet per plant I have gotten 800g and more from some bigger plants. This is under 1000w of HPS light in an aeroponic set up. I got about the same with a SOG PVC aeroponic set up with 600w HPS.
way to many variables to give you an estimate, it depends on plant size, genetics, amount of light given, nutrients, hydro or soil, indoor or outdoor, and many more variables
