I would give yourself at least 3x2, the reason being that I went 2x2 and have to order a specific cooltube just so it would fit, and that only works diagonally. I could fit 2 plants in my 2x2, but the way I did training in my grow I am crunched for space with just one. I am going to 2x4 for my next grow to give me more room for plants and equipment (having a hard time with fan placement).
Here is a 2x2 with one plant in a 3 gallon pot:

As you can see, its pretty cramped and proper airflow is challenging.
btw what is the thing directly above the plants? and are the white pipes just holding it up? is that big as thing a cooling tube?
