1st time growing having issues

i just started my grow on friday. i have 4 seeds that germinated within 12 hours. two boke soil on saturday and still hoping the other two will soon. i'm using a 400w mh in a 2x2x6 feet
closet but its actually 2x4x6. im only using that much of it though.i have a
250 cfm fan for the out take and a small fan for th intake, but temps keeps going above 90 so im just wonder if my light is too big for the space im using or do i just need bigger fans

u need a intake and outake fans with a light like that

a 400 w MH will give you great results in vegitative stage.... i would try using more fans and keeping the closet doors cracked open.... good luck
