I had intended that promotional idea to go to Roger Wheelock at Dampp-Chaser. As I head for 60 years, these little goofs seem to be happening more often than I'm able to remember. But, whilst I'm here, I may recall that humidistats are meant to switch over at from 42 to 48% RH, thus maintaining an average RH environment. If, as you said previously, humidity levels rarely fall below 45% there, you need nothing more than 50w bars run off the humidistat. While I have your attention, what's this about loose bridge pins. Do they not come in larger (or longer) sizes? Sorry for the goof. John Lillico,
