...i've got an ulster observation hive on order with plans to add a mic/amplifier (i've done this before in regluar lang hive), and a "sniffer tube" (hopefully with a one way valve so the bees can't be breathed on)....observation isn't only done with the eyes :) i'd be suprised if the levels of any mold/fungi in hive air would be enough to cause any discomfort...they do tend to keep a clean house with lots of ventilation afterall. deknow ****************************************************** * Full guidelines for BEE-L posting are at: * * http://www.honeybeeworld.com/bee-l/guidelines.htm * ******************************************************
