Hi, John.
This is a very long and confusing thread, with a lot of heavy info I'm afraid... but I think you'll find the answer to your question in post number 5 in the thread, here:

and in the three or...
Hi, TortsNTurtles.
No, I've never been sent the samples, unfortunately.
Bob MacCargar at ReptileUV has promised to send me a box of them on several occasions now but nothing has arrived.... :(
If you want to try something a bit different, have a look at the new T5-HO fluorescent tubes - either...
Hi, Bouaboua.
Good questions!
The UV Index of sunlight is a scale from zero to 11 or more. It can have a decimal point for readings between whole numbers, so for example UVI 3.1 is just above 3.0, then you'd get 3.2, 3.3 and so on... 3.5 is halfway between UVI 3.0 and 4.0...
On the UV...
Hi, folks.
I'm "cross posting" this from another thread in this forum, because this is a really good question on the MegaRay and I'm hoping some of you will be able to comment more on it.... :)
Bettinge asked me:
BobMac was one of the first - no, he WAS the first - person to send me a...

Hi, Bettinge.
Ooo... I've just noticed that there is already a thread on this product going, in this forum section.... This is a really good question, Bettinge - so I'm going to copy this post across to there, I hope that's okay... :D
So please go...
Hi, Bouaboua.
Yes and no... :(
I'm sorry, guys. This is going to be a long post. But I honestly don't know any really simple way of explaining this, so I'm going to work through it as carefully as I can, although I know it's a :tort::tort::tort: sort of thing to do to anyone so late at...
Hi, GTC and Tom.
No problems.... :D
Tom has explained this perfectly.
ZooMed are now selling the Solarmeter 6.5 UV Index Meter (still available direct from Solartech, purchase online or by phone for mail order, see www.solarmeter.com
The only difference is that the ZooMed meters...
I think it will become increasingly important to state this, because if an owner is using an infrared non-contact thermometer to check temperatures, they will never be reading air temperatures in areas receiving infrared radiation. I think there could be a big risk of people not providing enough...
This is very much how I see the use of a multi-T5 fixture set-up, too. I am very impressed by their possibilities.
I have a query about basking temperatures, though.
Are we talking about air temperatures or substrate temperatures?
I'm sure no self-respecting tortoise would be out basking in...
Kelly, my instinctive response to reading your description is "Yes! That totally sounds right!"
Do you have a data logger that records these parameters?
If so, then your recordings for the different habitats, for the species you keep, would be absolutely invaluable. Have you already published...
:D MikeH - this is a really great piece of research!
For species that don't need high basking temperatures (I guess that includes most tortoises?) this looks really worth pursuing!!
I'm not sure that one Reptisun 5.0 tube in a reflector at 14" distance is giving sufficient UVB. I'll need to...
I'll second that, Sandy.
I propose that someone with a humidity meter does some serious humidity measurements, with gradients across the WHOLE cage/tank/tub/tortoise table, across a huge range of substrate types, heater/lamp types and spraying routines.
This info ought to be out there!
A lot...
Tom, I had a friend (sadly we lost touch about 5 years ago and I never got a forwarding address) who was an absolute genius with frog husbandry. He was a pioneer with the use of both vitamin D3 and UVB with a whole range of reptiles - he was a devoted and skilled zookeeper - but with frogs he...
Hi, Erich.
Indeed. But green iguanas don't wear clothes.
And how many humans get 45 minutes exposure to the sun a week? In temperate climates, modern humans typically expose no more than 10% of their skin to daylight (head and bare arms and hands) and as for sunlight - how often do people...
But that's dreadful! A "prison cell".
That's exactly what these "tortoise starter kits" I see in so many pet stores are... prison cells.
At the risk of offending hundreds of people, which I do not intend to do deliberately... Why on earth are we improving methods of growing tortoises in prison...
Tom, Paludarium and Andy, I'd really value your thoughts on this. And others too, of course...

1. I'm sure most people, including all protagonists in this thread, would agree with me that tortoises are...
Hi, MikeH
That sounds a very nice fixture....
I don't suppose you're in the UK, anywhere near London? If you visit ZSL London Zoo, and go to the Galapagos Tortoise House you'll see what they've just installed in there - a massive array of four 4ft long Arcadia "SuperZoo" T5-HO units, each...
Mikeh, are you saying that the air throughout your entire enclosure is reaching 85 - 90F/ 30 - 35C ?
This is very strange - how do you achieve a temperature gradient? What is the air temperature in their hide?
If you are using buried heat cable then it will be heating the walls by conduction...
I have read the Weisner and Iben paper again, carefully, several times today, and I agree with Sulcata_Sandy.
There is nothing wrong with looking at just two variables at all - if you look at them carefully while taking appropriate measurements; control other variables properly; and have...
