Morning,

I am a noob in the Tarantula enviroment.

I need some info regarding a stable heating and keeping the humidity constant?

Does anybody have any suggestions?

Depends mainly on where you stay to be honest. I live in a rather cold area during winter and hot are during summer. So i just put my cages on heating pads during the night from around 6pm till 8am or perhaps even throughout the whole day.

You only need to heat half or rather 35% of your cage, the tarantula will move around if she gets too hot or too cold. I would avoid using heating lamps but that's just me

There are many options, but knowing you have 1 T at the moment and will grow a bit over time, I suggest you do what I do.

Now since direct heat on the enclosure is not advised, I have big 1.2mx35cmx35cm show case (I build mine myself). You can take one like they use for the bigger reptiles.

I then have 3 heating pads inside the case to keep the air in there nice and cozy. I then have my Ts in the case, the ambient temp of the inside will keep the enclosure nice and warm. Good idea to have a thermometer or two in there to find your hot and cold spots. The heating pads is more kind to provide a nice even temp, where a light will give you hotspots. If the room is cold, you might need more heating pads.

Hope this helps.

I insulated my house with isotherm , and put seals around all my doors and windows...

Leave a heater on half way and the room is around 23 degrees...and the tanks show 25...

They seem to 100% .

Just get your self a heating pad, put it against the wall or a cupboard and push the tank up against it!
Your heating pad will give your spider enough warmth!

You can turn the heating pad off in the morning depending how cold it gets or going to be during the day!

You don't have to worry about humidity as long as the substrate is a bit moist the tank will make its own.
Just make sure your tarantulas gets fresh water! depending how small or big the tarantula is you can give him a water bowl. just make sure the spider can't drown so give it a small rock or something that it can hold onto.

How big is the tarantulas in Question?

Morning,

Thank you for all the replies. I have a heat wire but it does not seem to be that effective. The T is about 4 - 5cm.
