and your girlfriend is too hot, your dick is too long, AND has too much girth. Your erections last for hours, and your diamond shoes are too tight.
let em sprawl. if the kids, the dog, and the old lady dont like having sticky hash covered clothes every time they walk by the kitchen, they should have let you build a growroom in the basement AMIRITE?
seriously though, unless your space is dinky they shouldnt be too crowded. i doubt they will get over 6 feet if you flower them indoors. Try growing a pineapple in your living room... shit gets REAL.
