If you are looking for cash crop, I would forget fluorescent lights. The fastest I have ever gotten done, 47 days on a 56 day grow. To do this I use a room with great ac (no need to vent out co2), a co2 generater, 1000w light/w cooltube, and aero in a single cola grow.
That being said, my father which grew for 27 years got a Omega a couple of years before he passed away. It was still really new tech. He had one 1000w bulb in it, and he averaged 2 and a half pounds a grow. The reason it isn't higher is because the plants stay short so less room for bud, and because it is a circle the plant tops grow close together so light has a hard time reaching the bottom leaves and bud. If you do get it only put in 150 plants, not the full 300. It is way too over crowded and your yield drops. My dad found out the hard way. Also do some testing before you buy. My dad had to send his first one back because the wheel stopped turning when the two wheels that meet get wet and all his plants died at day 42 of flowering on his first grow. It has been a while so I am sure they have worked out the problem by now that made his stop.
I get about 2.75 ponds in my aeroponic system. It is 5ftx5ft with mylar stands so I can move them to get to the plants and put them back around my system so it is like it is in a 5ftx5ft room in a bigger room. Otherwise 1000w light wouldn't cover a 5ftx5ft system very well. I use 4 in PVC tubes that hold 65 plants all together. I grow single cola 9in apart. The how to is in the GrowFAQ. Now for the bad of the system. If you lose power for 30 min's and you can't get the plants in water, they will probably die because there is no water or medium to hold water (the Omega uses rockwool). You need a back up Generater.
