Need help tweaking heat for Ball

[Sylorna]

So how do I increase the ambient temp without a lamp if the substrate is already too hot and I'm having to decrease the temp on that? The hot end is too hot and the cold end is too cold as it stands. What is the issue with putting a red 40watt bulb over the tank to increase the temp 5-10 degrees?

I'll order the hydrofarm to arrive in a week and a half and am going to adjust the cord in the mean time.

As mentioned, I have covered the lid a week ago.

I understand that people do not appreciate glass tanks, and I get it, however, I am trying to make due with what I have and what is available to me. In the future, when we have a house, perhaps I will take the time to create a build on a wooden unit, however I cannot do that until we have a house.
