If you are going to do vegging and flowering at the same time you will need two different lighting locations plus lighting setups. Another thought.....more for hydro than soil is that the type of water you use can be an issue. Many folks' tap water does not allow for a stable ph in hydro applications---with ph being an extremely necessary factor for success. In that case (and better to know sooner than after the fact) you may need to invest in an RO water filter.

Research is your best friend here. There's nothing worse than only being half prepared for trying to grow. Good luck.
