Sea kelp is perhaps the oldest known agricultural supplement. Its benefits are well documented over the centuries, across cultures and nations.

Sea kelp can benefit your plants no matter what stage of life the plant is in. Studies have found that soaking seeds in seaweed extract reduces transplant shock, and benefits the roots to grow at a more rapid rate and with more mass, and the plant’s overall survival rate becomes higher.
