Algen Extract plays a significant role in the health of your plant’s immune system, providing superior resistance to disease and pests.

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 color 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 an important supplement to the base nutrients of the plant. 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.


Algen Extract stimulates the growth of the root system enabling the plant to absorb more nutrients. It also increases the resistance of the plant and stimulates the production of chlorophyll. A larger root system guarantees improved growth during the entire season

Algen Extract Application

Prepare your nutrient container by first adding your base nutrient (e.g Cocos, Hydro or Soil) to the water container. Add your Algen Extract and other H&G additives. Adjust the pH value and EC according to the stage of plant growth.

Note: Algen extract may congeal or harden in your bottles. Due to it being such a concentrated and powerful product, packed with so many different compounds this may occur. Don’t worry, simply mix the Algen extract with water and mix vigorously. This should ensure further use for older bottles.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.

Nice cozy sweater, but handwashing is recommended

Great sweater for winters in the Midwest
Color: Black, Size: X-Large
Love this sweater! I went back and got another color! The fit is true to size and very comfy. The button detail on the sleeves just adds a little pizazz. The weight of the sweater is perfect for winters in the Midwest.

Flattering fit
Color: Dark Green, Size: XX-Large
This sweater is thick and stretchy but holds a nice shape, and is flattering on the body. The sleeves are nice and long too, which I really appreciate, being a tall person... the button detail is a great addition. True to size. I haven't washed it yet, and I imagine, based on the kind of woolly knit it is, that this sweater will eventually pill... but for now I'm enjoying being cozy and stylish. The deep green color is almost black green. I LOVE IT.

Love it
Color: Dark Green, Size: Small
I got the dark green. Love the sweater and it's warm. I do layer the sweater as well. It is as pictured. Size is perfect to me. I like sweaters to be longer and a bit wider in case it is freezing and I need to layer it. This sweater is perfect for layering. It comes closer to my backside, it is a little wide and not snug, and I like that the sleeves come over my wrists
