I wouldnt worry about it too much at the stages your at now. You've got a way to go with developing your new space first.
I never had to worry about humidity unless it was too humid. Good luck!

I actually have a humidifer just the problem is I cant keep the humidity up and the heat at the right levels in my grow closet.

yah i have the same problem mine stays at less then 30 and even running a humid.. it still only gets up to 45 max and thats about when it goes dry.. its by far my biggest problem

Try a Oil- Filled space heater with a good thermostat. This one is 15". Link: http://www.amazon.com/DeLonghi-TRN0812T-Oil-Filled-Radiator/dp/B000G1CXZI/ref=sr_1_4?ie=UTF8&s=home-garden&qid=1235020873&sr=1-4
