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.

Not indestructible
Color: Blue, Color: Blue
I bought & gave this toy to the dog 9/2/25 and this is what she did to it by 9/3/25. She is a stray pit lab mix, big dog, and I didn't think she was an aggressive chewer. Other people have said this toy lasted when others didn't, well this toy didn't last at all! At least she spit the pieces out. The same day I gave it to her she actually was starting to pull the little bumps off. Not sure if I will keep letting her play with it but she obviously needs something to chew on. It is pretty hard and well made, a little flexible in the middle.

Pineapple sunshine
Size: 7" XL-Large
Reviewing this after nearly 4 years. I got this for my dog (sadly has passed away), and this was one of her favorite toys. It didn't squeak but the shape and size was what she loved. Big enough she could chomp on in it and I didn't need to worry about her choking. Small enough she could carry it in her mouth when she wanted to play. This is a durable rubber/rubber-like material, I'd compare it to Kong toys, excellent for a dog who loves to chew and needs a toy that can endure their bite.
