Every cross section of pyramided bone I've seen has been porous. Have you seen one that wasn't?

Ansh said:This thread is taking an interesting turn. EJ, could you point me to any specific references suggesting that bone porosity is absent in pyramided bone? I would really like to study this aspect as it fascinates me. As a practicing rheumatologist I have lots of experience with MBD in humans. In humans osteoporotic bone is less dense. But a number of other metabolic bone diseases have completely normal bone density, and yet have bone that is brittle and of poor quality. Most importantly, the quality of bone often has very little impact on the general state of health in such patients. And so the question is, does pyramided bone fall into this spectrum of bone disease where the usual parameters for assessing bone quality are not useful.

I apologise if this is the wrong place for this discussion. Please move this post to a different section if appropriate.

I can't believe how much they have grown and how quick 3 years passed by. Needless to say, they are beautiful. This thread inspired me to raise my star in a humid environment (well semi-humid anyways with a humid box, frequent baths and direct-shell spraying), although I was afraid she'd get RI, but she never did. Keep up the good work, Tom. I love these experiment threads - also because of the regular growth updates and pictures.

I would cover the vents to prevent the heat exchange to the room. My closed chambers have no vents. It stays constant temperature and constant humidity inside. I open my tortoise cage always
2-3 time each day, so they always have fresh air.
Tom said:Yep. I agree with Ken. If you are losing warmth and humidity, there is too much ventilation. With what you were describing, I was expecting your enclosure to have an open top. Then I read a little further.
Can you post a pic?
Cowboy_Ken said:So in my opinion, if you are opening your enclosure to feed once a day, you are providing e good air exchange. As far as how many/much to plug you need to experiment. I have zero vents.
Tom said:I would close them off and see what happens with your heat and humidity. Every enclosure is different and everyone must make adjustments based on the readings from their thermometers and hygrometers.
My closed chambers have no vents at all, but they are not air tight either. And as Ken mentioned, opening the doors a few times a day for soaking feeding, water bowl cleaning, etc., allows for a decent amount of air exchange.
I predict things will get a little better with each one of those vent you close.
