By the way, I don't think heat will be a factor, so if more lighting is required for the yield I am looking for, it should not be a problem to get set up (though money might be a limiting factor). I've designed lighting systems over reef aquariums in the thousands of watts where the tank had to stay at 78F with no more than 1 or 2 (maximum) degrees variation throughout the day (regardless of whether the lights were on or off). I'm not at all concerned with the hardware set up, but rather with the actual growing of the plants.

I've considered hydroponics but would prefer soil just for the simplicity and lower cost.

Thanks again!
