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.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!
