I see (I think) so your valuing ventilation in so far as it allows you to establish an appropriate tempature gradient.No, only because temperatures in the tank are usually going to be more important. So, ventilation is usually considered adequate if the temperatures are proper.
Inadequate ventilation would not allow enough heat to escape to keep your cool side. Or cause temperature to drift up constantly over the course of the day. Is that correct?
By the same token would you say an enclosure where heat drops off quickly as you move away from the basking lamp is over ventilated? My enclosure may fall into this category as the warm end of the enclosure falls pretty quickly towards the cool end of the spectrum, leaving me with more of a warm quarter than a warm side.
This would mean the appropriate amount of ventilation would change as the R-value of your enclosure changes, as well as the heat output by your lights.
I was under the impression that ventilation was desired to move fresh air into the enclosure rather than just a tool to facilitate the transfer of heat. Is the theory that any ventilation sufficient to establish your temperature gradient will also be enough to remove "stale" air from the enclosure?
I would think that would lead to a very wide range in airflow depending on enclosure design, leaving me wishing there was a way to measure it properly.
Ah, I knew the high/low placement increased airflow. I did not realize it would do so to such an extent it could overcome the huge difference in surface area. I imagine this could potentially allow air to flow more evenly as well, or conversely lead to more dead pockets if the placement is not precise. Again I find myself wishing there was an "airflow meter". As usual I am vexed by things I can't measure.A normal tank with a mesh top is going to have plenty of ventilation. A DIY enclosure is typically going to be equal to better in ventilation even with smaller vent holes due to placement of them. A convection will
occur, and is usually what is attempted by placing vents low and high.
A link would be great. Or I can look it up if you feel it's a derailment of the thread. I would imagine testing your ability to measure humidity is germane to the topic of lowering humidity but alas derailment is another quantity I am unable to measureIt would be easy to test, you'd really only need to test one of your hygrometers if the other two agree. I've posted the "Salt Test" a few times over the years for testing hygrometers. If you're unfamiliar with it I can post a guide or a link to another guide on it.
