Is this setup right?

i still havent started growin yet, b/c im still buying some supplies and i need a few more questions answered cuz i dont my circumstances to fck it up, itll be my first time growi indoors so... ok, im either going to use this setup, which ive already assembled, where i have a stack of boxes in the back of my walk in closet, the boxes cover the whole wall side to side 5 feet up. this is gonna be hard to explain so bear with me. i hollowed the boxes out (the top and bottom walls of cardboard) and stacked em all up and so it looks like jst a stack of boxes for storage but it has much more space inside. Esentialy, 1 1/2 foot by 1 1/2 foot by 5 feet tall box disguised as a stack of boxes. problem is its tall enough, but i dont know if its a wide enough grow box. ??
hope this isnt too long which it is but o well, my other setup idea i got from bloodshot, showing a table stand with lights mounted under it and some sort of drab, tabestry, black vinyl, or paper anying light proof draped over it, my big problem is, MY MOM, she likes to go in my room and rearrange stuff and hang my clothes up for me u know being nice which i would usually be fine with except when i have a garden of doobage 3 feet away from where shes standing. i will be buyin a air purifier or negative ions things that takes smell away too. but i badly need this post answered, so if theres anything about it u dont understand then ask me and ill simplify it for u so that u can help me out cuz thats wut GC is all aout. thanx

 

i like ur setup better than any of the ones other people have given me, i think if i dont get more creative tonight ill definatly start puttin it all together and gettin ready to grow in the next 24 hrs
