Egg Carton Greenhouse
What you’ll need:
bottom of egg carton
flower or vegetable seeds
Fill carton with potting soil and add flower or vegetable seeds to each cup.
Water the soil well, and then put them in an individual plastic bag.
Keep the cartons in the bag, on a windowsill until flowers start sprouting up (you won’t have to water that whole time!). Once there’s some green, take the carton out of the bag and keep the soil moist. Then you can plant the entire carton in a window box/rectangular planter!
(*You could also add half an eggshell in each cup before filling with soil – for added nutrients! Don’t forget to poke a hole at the bottom.)[Photos from grdnbklyn]
