Glad this tip is helping you guys. Keep in mind, you can get PVC pipe cheap or even FREE, if you just keep your eyes open!

The portable mini-greenhouse does not have a floor to it. The frame is set over wherever you set your seedlings trays. If you want to, I suppose you could redesign it to have a floor so you could carry your seedling trays - but, keep in mind, picking up trays of seedlings will add to the overall weight. And, if you don't glue the couplers together before you move any trays sitting on a bottom, you run the risk of the bottom falling out.
Just be mindful!
