I use this shorter wire shelf on a covered porch to protect seedling trays from direct sunlight. That works great! I line the shelves with nylon fabric sold at hardware stores. I have about 9 of these shelves that are used exclusively outdoors and in the greenhouse. They are strong, durable, quick and easy to assemble and hold up great!
