    Re: Bee-shed idea ...

    Thanks LJ, Nice to hear of a good experience and a "just do it" attitutde. I am very interested in the temperature you defined as "around 25 -26 C" . Where and how did you measure that value? Did...
  2. Re: How do bees ventilate in the winter?

    What do you mean by "ventilate"? What is the intended function you are asking about? Water vapor, CO2 or temperature control?

    Use Titebond III and do not end grain nail - I uses an airgun, 5/8" braids and nailed-down-plywood rectangular-square jig for my frames while nailing/gunning - never broke or pulled out a fraem's...

    Poll: Re: Engineering Project

    I recycle or re-purpose old fence boards, especially from my fences. 2nd choice is local rough sawn lumber, milled one side, rough in, dovetail and Titebond III glue - no nails or screws. I also...

    Re: Bee-shed idea ...

    Lighting LJ, I believe Seeley uses infrared lights in his studies to avoid disturbing the bees. I am running a crude, warmed closet test with a weak nuc ( helps generate questions). A short...
  6. Sticky: Re: Hive designs and their advantages and disadvantages

    Juhani Linden,
    I wonder if the low relative humidity (RH) - cold air can cause a dyhration problem if allowed to vent vertically through a hive. Similar to trying to keep the RH up when running...

    Re: OAV in the winter?

    I had searched for awhile to find a basis for the 37F number. It seems to be rooted in a European statistical study that showed efficacy falling off cliff at 37F. Knowing my bees are still raising...
  8. Sticky: Re: treating vs. not treating for mites: opinion thread

    "As mite drift from affected to unaffected hives is now documented by the Peck and Seeley paper, " : I live in an suburban-ocean-farming area. Apparently the area contains no-treat or unknowing...
  9. Re: How much honey could one expect from one hive? Spring

    Let's do the math but wait a minute the weather is about to change......................snow today! :)
  10. Sticky: Re: Hive designs and their advantages and disadvantages

    Thanks JoushaW more reinforcement,

    Early hive expansion was also reported by Owen in his massive thermocouple study in the 1950s ( I shall reread and study his isotherms this winter as I am more...
  11. Sticky: Re: Hive designs and their advantages and disadvantages

    Thanks for the reinforcing information clong,

    We have similar experiences in different environments with a small time shift. I am at the 8 to 11 hive apiary stage and do not intend to grow. My...
  12. Sticky: Re: Hive designs and their advantages and disadvantages

    Think about the impact or airflow / boundary layer around the body when flying, heat and moisture loses, sensors etc. The electrostatic buildup and discharge question is a good one as when we did...
  13. Sticky: Re: Hive designs and their advantages and disadvantages

    Who drew "first blood" LJ ? I pay pretty close attention to this particular subject, top vents and humidity. In particular "Derek Mitchell's research indicates that top ventilation in heavily...
  14. Sticky: Re: Hive designs and their advantages and disadvantages

    I have not had the mold problem after two winters. In fact i had more mold with the standard no insulation, top vent approach. But the bees were dead when I saw mold so free water may have...
  15. Sticky: Re: Hive designs and their advantages and disadvantages

    Thanks for adding a word to my vocabulary, "poikilothermic ". I am aware of the concept but simply defined it (to myself) as a honey bee life and death system requirement with a wide temperature...
  16. Sticky: Re: Hive designs and their advantages and disadvantages

    I live on the north eastern seaboard and also have lots of connected days of high humidity, fog, mist and light rain. I have moved a few miles away form the ocean to avoid having mold grow in my...
  17. Sticky: Re: Hive designs and their advantages and disadvantages

    Congratulations on the "treatment free" hives! I'm 50 years into applied engineering going into 5th years of beekeeping. I raise my own bees and some queens but have to treat in the Fall winter.

  18. Sticky: Re: Hive designs and their advantages and disadvantages

    Ventilation or moisture controll is a difficult issue to discuss. Dereck Mitchell has done a nice job of critiquing E.B. Wedmore's conclusions which are based on one thermometer reading that a hive...
  19. Sticky: Re: Hive designs and their advantages and disadvantages

    I have read and saw a pic showing a PVC pipe vent from the bottom of the hive up to provide a vent to the void that normally forms under the snow. I would guess it was a CO2 issue as it is heavier...

    Re: Lowest observed foraging temperature

    I have watched bees on a sunny day but near freezing temperatures, foraging for water, I think. Right at the edge of melting snow and long grass. I was very surprised that they would take something...

    Re: Global Warming

    " It was changed because global warming just was not happening." Well it's one heck of a long heating up cycle - at least 76 years. Actually, I like it warmer here - now :) . Every action has...

    Sticky: Re: Anatomy of a mite crash.

    I like your "freezing brood frames" approach and agree with watching phoretic mite drop as an indicator. I also do brood removal and varroa -capped cell inspections. I have been thinking of doing...
  23. Re: new beehive designed to stop bees from dying over winter, and to have 24/7 monito

    "how to tell" what is good and working? This is the same question I asked of Dennis vanEngelsdorp when he was speaking in Ma. about BIP statistical data collection. He did not quite understand me...

    Hive Enclosure Design: I am fifth year beekeeper who has done a lot of simple experimentation on hive design while learning to maintain a sustainable apiary. I have been successful in over-wintering...

    Re: Band heater vaporizer.

    I would be very careful with the increased dosage logic. There are issues and limits. One of Dr. Ellis's reports showed redistribution or "spreading" of OA by bees in a short period of time. One...
