Walmart has nice and simple Accurite ones for around $10 and soldering irons are a little less than that. My tub was showing around 75-80%, so I added another row of ventilation holes. Now it is perfect like my other racks. If it is in fact really that high I would purchase a soldering iron and make some more ventilation.
Thank you! I will definitely look into getting a Soldering Pen. I didn't have any condensation :S Maybe my Hygrometer is off? I even felt the substrate and it was still pretty dry. I do plan on getting some Thermo/Hygrometers from Acu-Rite also.
