i want to start growing indoors, and id like to build my own grow box but i have a few questions first though. Biggest one is if i do start growing a plant is it always gonna be in the box or am i messing uo the concept, and prefferably id like the box to be about 5' high max. but id heard that they grow up to 5, 6 feet tall or taller. or are there plants that are short? im really "green" at this stuff ha no pun intended so thanks for the patience yall
