no disrespect but why u hatin' on tha man hes probly just got height or stealth issues maybe he needs a more horizontal box i know i do but im doing a micro-grow for stealth reasons but im just using plasitc tupperware get one thats big enough and it ll work
P.S it will probly rip the shoe box becuz when u water the plant the shoe box will get wet and rip easy or if the humidity is right and he box is left wet u could get mold even and then shock ur plant by transplanting it
ya man layer it with plastic that ll work and since ur using a shoe box im guessing ur going with a cheap budget so just use a garbage bag and fold it until it fits inside the shoe box and then either have it too big so it sticks out so no water can get around it or tape it OVER the tip of the top of the box so its over the WHOLE box and no water can seep threw
