temps and general questions on pc grow

hey guys im new to growing, ive always bought, thought id try this and see how it goes. ive been doin research and was wondering what are good temps for a pc grow and do i really need an exhaust fan, i have an intake but i wasnt sure ive i really needed an exhaust one. thanks for the help guys.

in small grows an exhaust is generally used over an intake fan. Pull the hot air out, sucking air in from bottom, negative inside pressure. temps 95 MAX and they start to get angry. try to keep high 80s or so.

ok thanks, also ive done alot of research on how to grow inside but i havnt really got a good idea, like what all do i do, how do i care for the plant and all. sorry man ima new at this. my dad grew when he was my age but he wont tell me how he says to igure it out on my own, lol. can i get some help?

UPDATE::
got smart, had a friend that was sellin a sub box for 2 15s and took it. this will def give me more room for a good grow. i just need a lil help on the setup and what kinda soil should i use and nutrients and so on. give me some comments guys. i need it
