A small oil filled electric heater would work, they’re pretty safe, but, if you don’t have a smoke detector in the tent, you should.How do I heat a 3x3 closet for growing. It's in my garage. Night temps will reach maybe 40 degrees.
How many watts does it consume?You might look into the heater from AC Infinity.
I use a lot of AC Infinity gear and am pleased with the results. You can put the heater in a tent and set it and forget it. It's can be set to run in different time on/time off cycles or to keep temperature in range or VPD in range, etc.
In my set up, the heater is outside the tent with a hose coming into the tent via one of the ports. The heater, along with the rest of the equipment, is controlled by the Controller 69 which has a tiny probe in the tent.
I used a oil filled heater and then a "panel" heater but went with the AC Infinity heater because it's a forced air heater so it heats up very quickly, delivering warm air wherever I aim the hose.

That's the max. The nice thing about having a "smart device" is that it will vary based on the settings. I think it varies both the fan speed and the temp of the warm air.How many watts does it consume?
I see 530 watts max on their website.
