question

do you need a exhaust on a full enclosed grow? well its usually closed it has doors but there closed most of the time

Probably.. depending on how small your room is and what light you have. Just opening the door once or twice a day is usually enough for fresh air. Heat is another thing -- you want to keep your temps in the high 70's / low 80's. A HID light in a closet will easily push temps into the 90-100 range.

my room is 55in. high x 261/2in. long x 141/2in. deep. i lined it in mylar (no ventation as of now). i need small fans to circualte air does anyone have any ideas for a couple fans? i need to get a thermometer/hygrometer but havent looked for one yet. im goin to start with CFLs or floros how many should i have for that size room? and start with the cool blue bulbs for seedlings and vegitation right? i do have a 150w HPS security light but idk if ill use that. if i do get a HID like a MH/HPS system what size would be suitable for that room? im going to start the seedlings in rockwool in a dome and then put them into soil after the reach the top of the dome and last thing what other things might i need inside my room?

bump......

Help me!!!!!!
