I usually do not use trays for my outdoor plants. Just to carry them indoors at winter and then back outdoors in spring and unloading them from the trays.
Last year I was lazy and kept many of my pots in the Sterilite 27 Quart Storage Box / trays.

It was nicer in the trays as I did not have to water the plants every other day because when it rained it filled the trays up. I ended up going through less gallons of water this way.
But there is a problem. The suns UV rays destroy the plastic making them very brittle and done after a season.
So I'm looking for UV trays about the same size as the Sterilite 27 Quart Storage Box item 1956 - 23"L x 16 3/4"W x 5 7/8"H. Anyone have any idea where to find something like that?
