I got tired of fussing with big jars and plastic boxes, puching holes, using tape and string to keep covers on. My favorite part is being able to see all the activity more easily. It's no fun if you can't watch them grow. I didn't order the floor tray so I cut some cardboard and covered it with foil. Made it stable so I could move it. Love that it's fine netting on three sides and the top, and a clear plastic side for viewing.
