You know what, this may look like an inverted storage bin, BUT what it is when it's upside down and resting on it's lid, AND you put it outside in the back yard with a couple of lines cris-crossed over it to keep it from blowing away...., it will act as a tiny greenhouse IF you are unsure if the frosts and snow have ended. Put your seedling veg plants inside, on the inner surface of the lid that's resting on the ground, and replace the bin over top...add something to hold it against the wind and voila....

Wife has been doing this for years

Lol, we don't dare plant anything outside 'till after Memorial Day.....We can cheat a little bit with our small greenhouse......
