2x4 or 4x4 tent for 8 bulb T5?

Which one would be better? It seems the 2x4 would be perfect, but was unsure if it would be a little hot... This will be used as a veg/clone tent only

With decent air flow and exhaust, heat shouldn't be a problem. 2x4 would get the job done if its just gonna be for veg and clones

personally I run a 4x4 allows for more room when it's time to feed and rotate the girls. I veg in my tent then drop into my room. makes life easier for sure.
