Grow Bags are used to protect oyster and clam seed from predators. Place 100 oyster seeds or 250 clam seeds per bag. When growing clams in grow bags, you must secure the bag down with rebar stakes. If using multiple bags, you will rope, cable ties and rebar to secure the bags to the ground. One end of the grow bags will be closed. 

Grow Bag Dimensions: 20.5" X 39.5"
