Hey and welcome.

If you wanna raise humidity a bit more hang a towel or a cloth of some sort in the water and then let that fan of yours blow on it as it sucks up water. Works quite well.

What lights are you planning to use later on? Stack more cfl's or something bigger?
I am always glad to see new grows here and especially WW's. Feel free to drop in on my WW log if you want and whatever I can help out with just ask.
Good luck m8.
