hey everyone, i want to start a small grow op. i havent got my plants going yet but i just wanted some opinions on the size of my spot. i found an old, metal locker in my shed it's 2 ft. deep, about 2 ft. wide and about 7 ft. tall. im going to bring it into the house and clean it up, i figure i can get 1 or maybe 2 plants in there (big maybe). does it matter that it's metal? should i cover the inside with plastic or something? i dont have much space in my house so it's an ideal size but is it worth it?any help or opinions would be great!
