hmm actually i think the question is what plants do you want to get and get lighting to support that plant, or vice versa you have to start with something but if your going to go for a planted tank look for those special plant bulbs with the right kelvin and also the right spectrum And also read around the forums for threads on people talking about watts per gallon and see what suits you
planted tanks are great but require greater maintenance i hope in the long run you get to create a nice tank
thats IMO but im only a newbie who reads a lot so somebody correct me if im wrong
