I've been doing hydroponics for about 2years now. Hopefully you have some experience already as aeroponics is much less forgiving. I have a 250w mh that just spreads enough to fill the corners on a 24" x44" tray Hung at heights of 4-6ft depending on plant life cycle.
A couple of points:
1. Organic nutrients are a no go for fine mist sprayers, no experience with nebulizers. This includes your fish poo laden used aq water.
2. The lens cover is your friend!! The plants will eventually try to reach into the light, scorching themselves and risking a fire.
3. Use only ventilated reflectors. With the lens and ventilation your plants can grow right up to the light with no damage. Plus you can pipe a good bit of heat directly out of the room.
4. Be prepared for 90+ degree room at 75% humidity...and bugs. You may need a reservoir cooler.
Imho, if the set up doesn't look nice and take more than 4hrs maintenance per week I tend to ignore it and the plants suffer, hence my move toward tanks and away from hydro. Besides, lights are expensive and soil-less is much more touchy. Those tomatoes get expensive!
Oh, chili peppers have been more forgiving than bells for me, and they're a good stout plant to learn how to enduce flower. Good luck!
