Hmm, hmm, hmm. Mulling over humidity lately for a home made bator. Has anyone tried both the air pump (set inside the bator) + air stone set up to raise humidity as well as tried an ultrasonic fog maker set up? Which one raises humidity more? If I go with the first, I'm thinking of using those weighted bubble wands, a large one. Even if you've only tried one or the other, any input and opinions would be great! What size air pumps/foggers did you use, and what did you get your humidity up to?
