If you want to accelerate that process, make a mini greenhouse from a plastic soda bottle.
This is an easy DIY project.
First, cut the top half of the bottle with a utility knife.
Next, add some soil and seeds to a planter, and be sure to water them.
Finally, take the top half of the plastic bottle, place it over the planter and set the mini greenhouse near a sunny window.
