I am looking to buy one lighting system that will work well for both foliage and flowering, if there is such a thing. From reading the lighting posts, it seems that the choices include:

1. Conversion bulbs

2. Dual spectrum ballasts that can run HPS or MH

3. Ceramic metal halide(CMH);

and, maybe more.

I want to keep things simple and purchase a system that will satisfy me over the long haul and be versatile.

Recommendations? Thanks
