Reuse your old Nespresso capsules as tiny pots for growing seedlings.
Remove the top of the capsule and clean the capsule. Add some nice soil and your seeds. Place the capsules in the tray on a small plate. Water all of the pots at the same time by pouring some water on the plate.
The tray fits inside a cut off PET bottle that can be used to create a mini greenhouse.
The used capsules already have holes in the bottom to let water in and some sort of filter material that keeps the soil in place.
