I recently got a new hygro it has probes as where my old hygro did not it was a dial. The probe is smack dab in the middle.Apparently my humidity had been in the mid to low 40's even with the top covered in towels and misting the humidity seems to lower back down with in the hour. I have a 40g tank A uth and a lamp on the cool end keeping th ambient air in the 80's. Is there any other tricks any 1 has for humidity?
