how much can you get??

i was jsut wondering if its really evn worth my time, some people are telling me i will only get an ounce or two off each plant after about 2-3 months of growing, and others are telling me at least 4 ounces each. when i start my set up im going to be using either a 1000w hps/mh light and a 400w mh for veg. or 3-4 400w hps/mh lights.

how much do you think each plant will be able to yield after about 2-3 months of growing? i dont want to necessarily grow them huge cuz as i understand that just takes longer though yields more, im leaning more to the method of growing smaller and faster harvest, harvesting when i will be able to get about a qp off each plant if possible without taking forever.

what strain?
what medium?
what lights?
what nutes?
how many plants?
how much veg time?
how big of space?
have you grown before?
will you use co2 and other atmosphere enhancements?

im using early pearl i know its more of an outdoor plant but its supposed to have a good yield. this will be my first grow and im definately using soil to start with before i get into the more advanced growing techniques. i dont know what kind of soil yet, something dark and rich but but not too thick so air can penetrate a bit. i'll be suing mh for veg and hps fro budding for sure. i dont even really know what nutes are? i'll veg until their about 2-3 feet tall cuz i hear they will grow about another foot from bud and the bigger they are the longer it takes, i want to use many smaller plants that i can harvest regularly at a fast rate and have the next batch ready to bud when ready to harvest. i have an entire basement to work with but i don't want to use too much power so i dont attract attention. how much power do you think would be the most i could use if you have an idea? and yes i will definately be using co2 since it increases photosynthesis, probably the co2 pucks, maybe one of those big co2 tanks but not rright now. what toher enhancements could i use i have about $5000 i can spend on a set up

so many factors but a small indoor grow with one 1000 hps/mh could easily yield close to or over a pound.

2 to 4 oz per plant
