Items around the home can be used for starting your seeds. Items like plastic cups from smoothies, or just plain plastic cups work great. Plastic cups with lids are even better. You can keep the lids on until you see your seedlings, then just pop off the lid and leave it off.
Using the plastic in this way is great, theres no waste left behind after drinking from the plastic cut.
What I do first, is get some stones or pebbles and place them in the bottom of my cup, before adding my soil. This is a great way to start your fruit seeds as well as your veggie seeds.
