got help

hay everyone! i have assembled a grow room in the bathroom i have the setup in the tub. i have the reservoir running to the veg try and plane to just change trays and lights to flip it into the flowering room both are covered by black plastic (like a shower curtin lol) and mylar all over. i also have a carbon scrubber right over the tub and and connect to the fan/vent in the bathroom.my bathroom is 11ft x 5ft x 8ft. the tube is 3ft x 5ft x 8ft.
im planning on growing 60 seeds of feminized white widow.

my questions are:
how long do i need to veg the plants?
how long do the plants need to flower?
VERY IMPORTENT will the smell be detected by neighbors (i live in an apartment complex)?
how many watt of light do i need for florescent and for HPS?
what kind of nutrients do i need (names please)?

will a 1 carbon scrubber kill the oder of the plants when im pulling it and pushing it in to the bathroom vent?

i live in an apartment complex my apt is right on the street right over the side walk so i didnt want to do the grow in the closet cause of the smell also beacause i cant cut and holes in the apartment then it will be real noticable. my only concern as far as smell goes is the naighbers no 1 is going to come to my house during that time.

also how much electicity will be used in a month if anybody has any idea about that question.

i lost my job 4 months ago im on unemployment and now my wife lost hers my son's birthday is coming up and we spent half of our money on rent and almost all whats left over on this project. i have been reading on the internet and ppl been doin this for years. i just want my first harvest and im goin to cut it down to just my personal use. Right now we need the money too. i just hope i dont get caught and lose my family.

all advice is extremely appreciated thanks in advance.

Veg depend on how big you want them to be when they are done. You also have to judge my characteristics of the strain
Vegging for at least a month is recommended for a decent harvest. Soome plants double in size during flowering, some triple It depends on conditions genetics and lighting.

The plants need to flower as long as the breeder says so, if not more. You plant will basically tell you when its done, its fan leaves will yellow off and eventually the bud leaves to if you let it go that far. Fast finishing indicas can be quick at 50ish days of flowering, providing you get the right pheonotype.

send the smell out the bathroom window with a carbon filter, dont let air from your growroom go anywhere but out the window passing thru a carbon filter.

DO NOT skimp on your carbon scrubber if you are actually growing in an apartment. make cheap home made ones AND buy good ones. Use a bunch of Gonzo air deodorizers, too. Any and Everything you can - or you are going to go to get caught.
