LR, if you've spent anytime reading these threads, you'll find that many variables come into play when growing this wonderful plant, more than just lights and the system, you have genetics, nutrients, environment, plant husbandry skills, and the list goes on.
Any "guess-timate" you'd receive, would be just that, a guess. They only way to truly know what your yield would be is to pick a strain, pick a system, pick some nutes, and run with it. Once you harvest you would then have your answer.
Peace!
