Im thinking the fact you spray and bathe your torts most days is overiding any true outcome of your coconut experiment. You are in effect keeping them humid as well as using coconut oil, so we will never know if they are growing smooth because of the oil or the constant spray/bathing. The only way to prove this is to only put oil on one tort. Can you do this? The fact is that some of the more experienced tort keepers on here are growing smooth torts without coconutting them.
BTW. I'm glad you did this experiment because it highlighted the impact of hot spots to me. Most probably already new. Anyway my way to combat hot spots will be to create a smoother heat source. One way is to use a closed chamber with more of an ambient temp rather than a harsh hot area, and don't have the heat source too close to the torts. This said I have redfoots and i dont intend to have a specific basking area, just a heat gradient.
No, I will not su
OK, I went back and read a few pages. Glitch, I know you are very interested in the lighting aspect but it seems like you are not paying much attention to other aspects. You say you agree that the Hewwood method is effective but you don't do it. And your lights seem extremely close to your tortoises, at least that's what it looks like in the pictures. You said you don't plan on getting your tortoises outside for natural sunlight. Your enclosure seem a little small. It seems you are looking for a lighting system that along with the use of coconut oil, will make up for Bad husbandry in other areas. You say you want a lighting system that is foolproof. You are almost hostile towards suggestions to use different fixtures or different types and spacing of bulbs to spread out the UV and the heat over a wider area. You don't like the idea of a temperature gradient for adult tortoises. I stand by my previous statement, I feel you are creating the problems that you were trying to solve. You are rejecting what is basically considered proper husbandry and trying to find a quick fix all. Have you even considered the needs of different species of tortoises?
When this thread started I thought you might be onto something. Maybe you were but now I'm not sure what direction you're going.
I have been paying attention to all the aspects. My lamps are about 12 to 13 inches from the top of the tortoises shell and skin. Which is the recommended heights for the lamps i am using. it may look like they are close but they are all about 13 inches away from the top of the shell. My tortoises get outside about 2x to 3x times a week for about 20 to 30 minutes or so. My habitats are as big as i can allow inside my home. My habitats are 4.3 x 2.8. I also allow them running around time outside the habitat, as they have a pretty empty room that is safe for them to run around in. i try to take them out every single day for atleast 2 to 3 hours each of their habitats.
Until i am able to procure funds for new habitats this is what i am going to be working with.. I am able to properly hit the temp gradients needed in the habitats i am working with. My ambient temps are 85f. My basking is 96f. My cool zones which are my 5x humid hides go down to about 75f - 77f during the day time. At night my temps drop between 67 F. to 70F.
I am not against temp gradients... I just feel 90% of people think one heat bulb and UVb lamp is effective at creating a gradient temp properly. I see it all the time on facebook groups in their habitat pics. The most widely used set up is the 2x bulb set up. 1x Mercury vapor bulb on one side of the habitat. And 1x uvb bulb close by to the heat lamp. Then they think the rest of the habitat must be the "cool" zone. So its left pretty dark and cool.
That is arrogant and wrong. So pretty much your limiting the tortoise to the basking lamp and uvb lamp for heating and seeing light and keeping the rest of the habitat cool and dark. This right here is the common set up around the world when housing tortoises indoors. I have probably told over 300 people to add a second heating element and spread out the Uvb light so the tortoise can roam the table and be warm and see all over.Instead of being confined to a corner of the habitat. My tortoises like to be warm. And through observation when i keep my ambient temps at 85 f. He will fall asleep anywhere. Whereas, before when only giving him a single basking lamp (very early on in his care before i knew better). He was confined to the basking lamp section almost all day.
I feel the whole gradient guideline is being done incorrectly all over. People are offering incorrect temp gradients. I see it all the time on facebook groups. And i have a picture to show you all that shows exactly what i am talking about.
Also about my lamps. The lamp holders i have can be upgraded to the wider dome lamp holders. So i can get a tiny bit more spread in the bulbs themselves. But otherwise, i dont see where my issue is in my lighting scheme. I hit the gradients i need even in my smaller habitat. And being an open table top i need more powerful lamps to heat my area up, as its constantly being equalized by the surrounding air.
