Cycleman, I do not keep my sticks at any particular levels. I keep within a range. Humidity in the house maintains 55%-65%, temp in the house is kept at 65'. They are keep in tupperdors they hover at 60' sitting on the floor under bed, through out the year humidity wavers (in the bin) between 62-72% (depending on temp). When I have the heat of summer, when temp of tubs gets over 70', the tubs go in the basement, this knocks temp down to roughly 63'. They come back upstairs mid sept. This year however ther was a spike in humidity when I brought the lots upstairs 62' @ 72%. They have settled down to 62'@ 67% a wee bit high than I like. If the readings go under 65% I'll use a shot of water for the bin of boxes and water pillows and use till it gets back up to 72%. I then, for the most part, do not use any humidification until the humidity drops back below 65%.
But I think the real key is, as most will tell you, just buy'um faster than you smoke.
