Propagate your seeds indoors early in the season to give your flowers, herbs and vegetables a head start. With a handy propagator, every seed can begin life in its own little cell in the seed tray. Growing the seeds in their own little plugs makes it easier to prick the seedlings out for potting. The transparent lids covering the seed trays not only function as a greenhouse to create the perfect environment to promote growth, they also allow you to follow the daily progress of your seedlings. Should you need to leave your plants unattended for a few days, simply lay a watering mat in the bottom of the propagator.
