Nothing is more frustrating than when a gardener starts seeds and despite their best care efforts, they never sprout. The makeup of Aerogarden Grow Sponges can help avoid this painful event. The Canadian Peat Moss that the sponges are made of helps the seeds germinate quickly and grow healthily. It helps to provide the nutrients that the seeds need to come to life and helps to support the growth of strong, healthy roots. Many gardeners would even say that using peat moss can be more beneficial to seeds than typical garden soil.

The sponges can be used in Aerogarden products like the Grow Baskets or Seed Starter Systems but could be creatively used in other systems and set ups as well. They come in a pack of 50 for an affordable price.

They take away the messy and time consuming step of scooping soil. They are, however, still made of soil. These seed starters are simply compacted dirt. They can be used by placing the starter into a seed starting tray or cup and adding water. When the water soaks into the disk, the soil will expand and create a perfect seed starting environment.

Even though these disks are made of soil, they still help to create healthy seedlings. The soil is compacted so it able to hold onto extra water. This gives the plants more water and nutrients than they would get if they were planted in typical soil. It also has fibers similar to tubes in its soil which allow water to circulate and helps to prevent root rot, a common killer of well-planted seedlings.
