MJ and les,
Thanks for the suggestions. It is my understanding that for tomatoes, the more general spectrum light as I have, will cover all phases of the tomato plant's growth cycle. The HydroFarm guy may be correct when it comes to
other types of plants (which I am not interested in growing). I really don't want to have to fool around with two different bulb systems. This is supposed to be an educational (for me) and fun project.
