I bought a Homebox S for a closet grow (dimensions 31.5" x 31.5" x 64"). I am pleased with it! Came quickly and easy to put together. I am running an 8 plant hydro drip system and had a spill but the tent floor is completely sealed. I have a 400 watt MH/HPS that I exhaust with a 424 CFM 6" inline fan that does a good job at keeping my temps down. My temps with lights on range from 74-83 degrees. I exhaust my tent into an attic in my closet ceiling (I live in an apartment) with 6" flexible duct hose.
Well, that is just an idea of what you could do with a similar size area. It really depends on space available and amount of $ you are willing to spend. Many people are DIY types who enjoy building their stuff, but I am not that way so the ready to assemble tents I recommend to those like-minded.
Good luck with your grow (I have heard good things about Sensi Star....a strong indica!). jusbrowsin
