How to raise soil temps

I am having a problem keeping my soil warm in a 5 gal fabric pot inside grow tent. Temp inside tent is 72F and humidity is steady at 48-50% but the soil inside pot is 60F or lower sometimes. My heater sits next to the pot but does not heat the soil. Tent is 32x32x63

The led will not make it hot enough on it's own.. might not even the heater anymore.. I'd monitor it for a day :).. I hope this helps...

Consider shutting the extraction fan off. Especially if you have an Oscillating fan in the tent. Your grow tent will gain humidity and heat. Just turn the fan back on in a few weeks once the plant is more established..

Tent is sitting on carpet but when I raise the temperature of tent the humidity drops even more. Extraction fan is set on low. I am in Michigan and right now outside temps in high 20's and outside RH is 86%. since my pot is raised off of floor with drip tray underneath I filled drip tray with water to see if that helps. I dont want to waste money on nutes if the roots are too cold to uptake them?

The substrate will always be lower than the room temperature but the 12 degrees in such a small pot is an oddity. Are you on concrete? Insulate the bottom, raise grow tent temp to 78.
