Did you use 4x4's for the "floor joists" What size wood did you use on the floor??? Is it pressure treated??? I was worrried about loose corn falling through when the pressure treated shrinks.
Just FYI I used 4 x 8 x 16' Hemlock for my main beams and 4 x 4 oak for the joists. I decked mine with 1" thick oak boards...those shrunk and left gaps as well. If you are looking to make a floor that will not let kernals of corn fall through I think you'd have to shiplap the edges. I wouldn't think you'd want plywood because water would pool up when it rained...
