Is the tape along the top bit okay? None of it is inside the tank or accessible to the snake. He cannot touch any of it.
It looks like it is needed and as long as the snake cant reach it you should be fine.
We had to make the crappy little makeshift lid because without that the humidity spiked to 80%+ overnight because of poor air flow, even with about 3 dozen holes cut for air. I'll try covering some of the slots with a towel to hold in the heat better.
You are gonna be a bit frustrated but all you needed was a fan in the room moving some air to exchange the humidity a bit. In my snake room I run an oscillating fan to keep the air in the room moving to prevent the air inside my cage to become stagnant and hold to much humidity. When adding fan you don't want to point the fan at the cage and usually placing it on the opposite side in a corner works fine to move just enough air to drop the humidity a bit.
Thank you for the link to the herpstats, I'll look into saving enough to order one asap.
Herpstats are great and I have never seen one person with one not like it.
The lamp we have has a dimmer. Do you think the 100w dimmed would still be too hot? But good to know. I will be very wary when first using the bulb and monitor to make sure it doesn't get too hot. The room he's in is unfortunately rather cold, but still the warmest room in the house. It's an ambient temp of about 65-75 depending on the time of day.
A rheostat(dimmer) will work fine. If it were me Id start as low as I can and slowly go up. Adjust the light and then give it an hour to heat fully and rest. Recheck the temps and then adjust again. Do this slow. The 100watt bulb will really put out some heat at full power and may be able to still melt the plastic at the distance the fixture is from the plastic.
You can get rid of the heating pad you are using and get the get the 100watt bulb and dimmer dialed in to provide a good hotspot while giving you the correctly ambient temps. This will probably work best by raising the fixture some to allow the heat to spill over the lid a bit more to better heat the air and not create such a pin pointed hotspot. Using a lamp stand or setting a lamp up in a manner that keeps you from moving it or banging it will make the bulbs last longer too.
