Nothing has wilted as of tonight (about 18-22 hours after it happened) I guess I'll know in a few days...

I've seen a couple of min/max temp alarms in a catalog or two.. but they were all expensive (over $200). Anyone know of an affordable one? I haven't really looked online.. but its a priority now. I've seen some that even CALL you .. that'd be cool.. but really unnecessary since I'm usually home by the time the temps really drop...
