lighthouse hydro grow tents.?

is anybody currently using or has recently used a lighthouse hydro tent, was wondering about buying one because i heard it has the set up for air cooled hoods, i was looking to buy either the 4x4 or 5x5 but if anybody is using a size bigger or lil smaller with same kind of port set up let me know please?

guess no one uses them..?

Never Used it but if that's the case then that's awesome and could be a serious reason to buy it if you intend to have a sealed room for co2 and air conditioning or just want to separate yourself from the environment you would otherwise be in.
