250 Watt HPS lamp ok for 2x4 closet?

First Time grower dont know much but im doing my research. any help here and there would be great. Thanks

if u have a fan u should be ok

that is something else im looking at. do you think i should use a circulating fan or a enhaust fan

I would use both, 1 to suck out all that hot air and the other to circulate fresh air and make the stems strong
