    I built this thing and used it for 2 years. On one shelf. Now I added another. It is heated from the bottom. So it heats quicker at the bottom and cools off quicker. But my temps are going from 98 to a little over 102 on the bottom and 99 to 101 .8 on the top any ideals of what I can do to gt them closer together? I have a water bottle in the bottom to help with the temp.

    Do you have a fan in it? If not that is what I would try.. Adding a fan

    Yes I have a fan. It is not a PC fan. But a small desktop fan so plenty of air flow. Thanks

    One shelf works with just a fan but 2 is an issue. The shelves work to block air movement. The best fix is a false back with a fan in it pulling air from the top to the bottom. You can do the same with an external air duct too.

    You could try moving your fan to blow around the shelves or just add more fans.

    My floors are open. They are made of metal cubes. So that is not a problem.

    I just had the same experience with my mini fridge that I made. I added another shelf and the temperature was similar to yours. I experimented with adding another fan. My main heat and fan are on the top shelf. I added another pc fan set on med. and that equalized my temperatures on all three levels. I had to experiment before I found the best spot. Oh, my water is on the bottom. Hope this helps.

    I assumed you built the shelves out of something air could go threw. Getting good air movement an no thermal layering in a multilevel incubator is hard. Its going to take duct work or more than one fan.
