Yo Slip.. I think what these guys/gals are telling you is that... you should just get a book and read it.. really.. you will learn so much... I will pretend that I know some answers and give you what you want .. but don't get mad when I'm wrong.... 'cause they already told you to look in a book.. : )

questions
1. see to harvest... plant seed.. water seed.. seed grows under 18-24 hour light for 5-20 weeks then light cycle is switched to 12/12 and then 7-10 weeks later you harvest ... then you dry for 1-3 weeks.... total from seed to joint is 13-33 weeks. this all depends on how big you want your plants... and if they don;t get sick.. blah blah blah

2. You can expect 1/8 ounce to 10lbs of bud... yep I SAID IT... 1/8 ounce to 10lbs..
If you are growing outside and you're name is hemheadjack expect 10lbs if you're growing inside and your name is slipknotpsycho, expect 1/4 ounce...hhahahha
no just joking... sorry that was just a bad joke.. anyway... weight depends on two main factors size of plant and light.... other factors are... strain (what kind of bud), health of plant, nutrient levels, type of pruning etc..

question 3.. I think I already answered it above... good luck.. most people just talk, you are actually growing.. good for you : )
