Hi Ernie, I would like to know if you really need to have your system inside under lights, or could you set one up outside? Having done both, I would say that you might have a lot more freedom to build and operate a system outside. Growing inside under lights will be much more complicated to do, and unless you have a whole room to devote to it, the system will probably not produce a whole lot. If you were growing some exotic flower or plant that requires a special environment, then unless you set up a green house, growing inside under lights may be the answer. When you know for sure that your only option is to grow inside, then you might want to evaluate the size of the growing area. If it is really confined, you will need to use a light source that does not generate a lot of heat. On the other hand, if you do have a rome for growing that is atleast 6 ft X 6 ft, you could invest in a good metal halide or high pressure sodium lighting system. The system I purchased has a switch on the transformer that allows you to use either type of bulb. If you use the 1000 watt size light, you can use the whole 6X6 area. Another alternative is to build a grow box. There are several current postings now that have pictures of systems using florescent lighting in them to get good results. One is showing an aeroponic system, and in another posting some boc choy. My suggestion though is, if possible, you should start outside. I have just set up a simple to build system for testing out some ideas for emergency use. Look for my postings here about a siphon system and emergency systems, or use the link below. chuck
