You may want more, conventional wisdom says a higher RH is good for vegging. Myself, I have a somewhat low RH in my grows too (I'm at around 30 - 40%) and I just water more as I prefer that to worrying about mold. I wouldn't try and raise it during flowering unless low RH is giving you problems of some kind, low RH prevents bud rot.
If you do want to raise your RH, you can (in order of increasing complexity and expense):
-set out a small container of water and let it evaporate (for a very modest effect)
-set out a larger container of water with a fan over it (better effect)
-buy a humidifier and put it on a timer to run intermittently. Running it all the time typically isn't an option because the reservoirs in the things aren't that large.
-set up some kind of fogging system with an external res, maybe even hooked up to an RH sensor.
Other folks may have niftier ideas. I'd love to see some!

I've also read that a low RH is ideal for spider mites.....
