House & Garden Algen Extract 5 Liters

House & Garden Algen Extract is a concentrated solution of Norwegian Sea Kelp, (Ascophyllum nodosum). Plants in all phases of growth love kelp for the many benefits it provides. Micro nutrients, beneficial vitamins, and macro-nutrients are all present in Algen Extract. This helps ensure a better leaf colour and Algen Extract also stimulates the formation of fine root hairs, leading to increased uptake of various trace elements.

House & Garden Algen Extract is a premium blend of Norwegian Sea Kelp, containing high levels of active enzymes and cytokinin, as well as amino acids. Our Algen extract is extracted in cold water, which ensures the biological life remains intact and un-denatured. 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 very high levels of natural hormones, polysaccharides 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.

Perfect for soil and coco substrates!
