House & Garden Algen Extract is a premium blend of Norwegian Sea Kelp, containing high levels of active anzymes and cytokins, as well as amino acids. Our algen extract is cold water extracted ensuring the biological life remains intact. The extract is therefore rich in both macro nutrients (such as N, P, K, Ca, Mg & S) and micro nutrients (Mn, Cu, Fe & Zn). Algen Extract also contains seaweed which contains very high levels of natural hormones, polysaccharides, amino acids and proteins. These substances stimulate healthy root growth, which makes Algen Extract an important supplement to the base nutrients of the plant. Algen Extract plays a significant role in the health of your plant’s immune system, providing superior resistance to disease and pests. The Norwegian Kelp is very unique and its benefits will be evident within a couple of days. Spoil your plants with Algen Extract, and reap the rewards through faster, healthier growth.
