What I'm getting is completely irrelevant honestly. Take a look at the link in my sig and youll see why. Plus, your answer is somewhere in there. Unless you plan on replicating that exactly, its useless to know. I'm still dialing in my setups and jsut getting my consistent strains in order, so I've had improving harvests with each run and you shouldnt gauge your possible results off my current ones. I'm now in my own version of Happy Frog and using my own schedule of mixed-company nutrients that I've come to develop, in a very uniquely set up grow area and training style. My scrog is an experiment more than anything.
I know everyone hates getting the generic-sounding responses, but focus on getting your environment stable with the right conditions to eliminate outside stress: temps, RH(read up on VPD real quick, youll see how important it is), airflow/circulation, co2 if you choose. From there, just keep the plant green and youll get consistently solid harvests. How much exactly is going to depend on lighting, environment, training, setup, medium, health/vigor, strain. Anywhere close to 1gpw is a great harvest, as long as youre not vegging for 6 months to get it. People like to say 1gpw is the average and should pretty much be expected, but not many people are actually pulling over 2lbs from 1 light no matter what training method they use. Those that are have usually either been growing awhile or spent at least a couple grows dialing in their specific setup and routine. I'd hope for .5gpw your first couple times, itll go up from there as you tweak and improve things.
