Im a beginner needing some info before i start. Please help out

Hello,
 
this is my first post, hope I don't get banned seeing as how many accounts are banned on this forum but before I ask questions let me tell you about what I want to accomplish.
 
I live in a ghetto town where every colored person smokes weed. I have helped friends sell weed that they got cheap elsewhere before but, me and my friend were thinking about growing. We were going to do outdoor last season but it was too late to buy seeds. So now, until next outdoor season, I will be making pc grows. I don't expect too much weed but, ill be selling about 3-5 ounces as a goal. Maybe smoke the leftovers lol. 
 
So my first question, I will be making a pc case and I have already figured out the insulation and carbon filtering but, if anyone has any tips they would be greatly appreciated. And also, I have 1 led chip that I got off ebay a while ago, it is cool white and extremely bright about 3000 lm is what the seller said. It runs about 50w. Do you think I could use this and if so for veg or flowering state.
 
My second question is about the seed supplier. Has anyone ever heard of ilovegrowingmarijuana.com They have good reviews and seem legit but, just a review would be great. Also, if you have bought from them, how discreet were they? what did they ship in??Wrapped in shirt, DVD case, etc...? I need to know because if they are in dvd case I will buy another dvd off ebay or something so that the others in the house don't get suspicious why I bought 1 specific no brand item.
 
Also, considering the size of an average full size desktop case, how many ounces do you think I could get off 4 plants. 2 in each pc.?
Thank you very much in advance.
 
PS. I plan on buying 5 white widows and putting 2 in each pc and saving 1 seed for the new season. Il make a grow journal with photos when I start growing. Thanks
 

 

Btw, could you please explain to me what the light cycles are and how I can achieve them with my led if possible.
 
edit: heres a vid to show you my light. Its not my vid btw

thanks, now I think ill order fish gravel online also, so that my parents don't suspect anything. I still live with them for another year.
 
Ive been reading about some of the pc grows gc members have done, but still have 1 question, If I use a carbon filter can someone smell it if they put their nose up to the fan?
 
Thanks

 

isn't it like 4 inches wide? I saw this tut where the guy just attached 2 fans put on some chicken wire and a sock and filled it with active carbon. Plus I researched and I think my led will work well so Il have a shitload of extra space in the top.

 

thank you so much. youre pc looks so professional. I hope mine is like that. Im getting the case in a few days. How much bud do you think you could pull from each plant?

 

thanks. Its my first grow ever too! Hopefully itll only take a week or 2 before I get started. I have learned all the info I need and am ready for the growers life.lol
