Floppy disk planters are a great way to use old floppy disks that you may have lying around. They are made simply from floppies glued together to form a cube and adding a liner on the inside.
It's one of those common-knowledge things, like how playing classical music makes plants grow better. If a plant is reassured that there are no bad sectors in it's planter, it thrives.
So...if you splash water around when watering the plants, I assume the diskettes will grow all the way up to 8" floppys? And the file sizes will also expand?
