I am getting ready to build a fairly permanent wood Crib. I am taking the pallet approach a step further. Landscape timber bottom rails with 5/4 decking on top of them, 5' tall 2x4 ends with decking across those. My question is this; i was planning on going 6' wide (overall dimensions would be 32' Long X5' Tall X 6' Wide) Is 6' too wide for adequate airflow. The pallet setup i used last year was a standard pallet width and worked great but the pallets are rotting.
