You can get the same or better-growing results with seed starting tray that you make. all you need is a good container (with good depth of about 3 inches that the plant roots can grow into) with holes at the bottom and seed starting mix or soil.
How to Make self-watering Seed Starting Tray
Get two aluminum trays, of the same size and dept, if they have been used, wash and rinse them.
Make about 9 to 12 holes at the bottom of one tray. put the other tray aside for later
Fill the trays with holes with your seed starter mix. you can save money by making your own seed starter mix. Read my post on how to make your own seed starting mix. Fill the tray up to 80 percent, this will give the seedlings more space for their roots to grow in to.
Get the other tray with no holes and put 2 or 3 pieces of wood or any other material. the wood should be about 1 to 2 inch high. The wood will support the other tray and give you more space to serve as a water reservoir.
Put the tray with seed starter mix inside the tray with the wood, plant your seeds in the seed starter mix (follow the seed package instructions) and thoroughly water the seed starter mix and seeds in the tray.
Cover the seeds with a plastic bag or an other aluminum trays and place the tray or container in a warm area.
within a few days or a week, your seeds will begin to germinate. once they germinate and begin to put down more roots, you can start adding water on the bottom tray.
