Seaweed has evolved to thrive in extreme ocean environments, and when applied to your crops it helps build plant health and tolerance to a wider range of growing conditions. Growing in salty water, one of its particularly popular uses is helping plants efficiently regulate their hydration, resulting in greener, happier plants if water is not perfectly available. ALGA liquid seaweed contains vitamins, natural chelating agents and amino acids.
