You don't have to have an additional area for starting seeds with these trays. Loaded with plugs they sink 1/4" into the water to wick up nutrients and water. Since germaination does not require light, you can place them in your fish tank to help insulate the tank. They don't use valueable growing space, yet have access to the same nutrients and water your plants need. 

 

They can also be placed a one end of your media beds. Whenever the media bed floods the seedling plugs are automatically watered.

 

When seeds germinate just remove them from the tray with tweezers and drop them in the raft.
