A seaweed farming system may include a harvesting unit. The harvesting unit may include a harvest disintegrator. The harvest disintegrator may be configured to receive a plantation substrate having mature seaweed thereon after severing a vegetative portion of seaweed. The harvesting unit may further be configured to disintegrate the mature seaweed to separate the mature seaweed from the plantation substrate, the plantation substrate remaining intact during separation of the mature seaweed.
