Maintaining Optimal Temperature in Small Tent

The 2x2 part will be fine... It's the 3ft of height that will be an issue. Think about the height of the container the plant will be in, the amount of distance you need to leave between the light and the top of the plant, plus the amount of height the light itself occupies and there really isn't much vertical space left for the plant.

The colder night is compared to day, the more stretch you will have. Run a simple ceramic wall heater, I think they have a built-in 25C thermostat. They are sized by room, but generally only pull a few hundred Watts.

Controlling temperature and humidity day and night is the key to growing good weed.

Be careful with Northern Lights.... the Autos can get quite large. I've seen them 4 feet tall.... for an Auto.

True story. I only ran autos twice and one of them was a NL auto from nirvana. Plant finished at about 3.5ft tall.
