You know, those cell pack things that when you buy a pack of little plants, they come in something like this: http://www.cozycabinnursery.com/buy/images/uploads/Trays-Pots/tray-insert-72-cells-1206.jpg

And also the trays that these fit into to catch water, the ones with no holes.

Maybe some one knows of a local place? I'm in Montgomery Co. MD. Or maybe some one could suggest an online place? I need a lot and different cell sizes but definably not in wholesale amounts. I don't care if they're used.

Thanks for any help!
