how do u run 4000k to a grow room?

i am setting up a 2600 k grow room or about 35 amps.the room wiil not handle that load,can someone tell me what kind of wire i need to run from the main breaker box to the growroom,and is 35 amps enough for 2600 watts plus fans and pumps and whatnot.what type of breaker do i need for the main box to hook the wire up?do i need to put a subpanel in the grow room,or something else.I CANNOT hire someone nor do i trust anyone to do the work for me,i have to do it myself,thats why i need some real technical support here guys!

best bet is to run the lights as a 220 circuit and add a 115 circuit for the extras. 12/3 romex will work for the lights (10/3 would be better)
12/2 for the extras, a 20amp 220 breaker for the lights and a 20 amp breaker for the extras would do it,u need to know what make your box is as breakers are not 1 size fits all
a sub panel would be the ideal way to go but not a job for someone w/ limited experience but the above will work & would be better for someone w/ limited experience. get a book on basic wiring. the info needed would be to much to spell out here,it will fill a book(picture help to)
