more is definitely better. i ran 4 for the most part of my 4 plant gro, and now i regret that i didnt add my extra 3 bulbs at the beginning. the extra bulbs stopped upward growth almost totally and helped branch em.

i go w/ 23w ones if i got enough sockets, since theyre the most price: lumens efficiency
