Seaweed Seed

The Seaweed Seed is a seed added by Pam's HarvestCraft, which grows into an Seaweed Plant on Farmland. When broken, it will drop nothing. However, when right-clicked, it will drop 1 Seaweed (or 1-2 Seaweeds before version 1.8.9a) and the crop's growth will go back to its pre-mature form. Bone Meal may cause the crop to grow one stage, just like regular Vanilla crops.

Recipe
Seaweed Seeds can also be obtained from the Soggy Garden (or from the Water Garden before version 1.8.9a) or from breaking Grass if configured.
