First Time Growing Help plz

Tell me if this is a good idea and tell me what i need to change thanks

i buying a grow tent 76x76x76

I dont know what lights i should buy?

and im just going to buy realgar fans

and im going to buy Acu Rite Indoor Humidity
Monitor

and im not home every day so what kind of automatic water system should i buy? thanks and add tip if you want!

400 or 600w would be good. i would buy a inline fan & filter as well for odor control and heat control as well. get a air cooled hood.

I am a noob.... But I think if it was me I would buy a light with a vented hood to help control the heat if I wasnt going to be there everyday to monitor it.
Also before putting plants in there I would do a dry run with the lights on and fans going to test it out and monitor the heat.
Also I would probably go with at least a 600w to maximize the space available.

grab a book by Jorge Cervantes or Ed Rosenthal before you buy anything and learn and educate yourself as to what you are planning on doing.
