House & Garden Algen Extract - 1 Litre

House & Garden Algen Extract is a sea kelp extract additive designed to support a stronger root zone and vigorous vegetative growth for container-grown plants. This concentrated kelp solution is a plant supplement that brings the natural benefits of Norwegian sea kelp into an easy, consistent format.

Built around cold-pressed Norwegian sea kelp, Algen Extract focuses on root hair growth and overall root zone performance. By encouraging finer root hair biomass, it helps improve trace element uptake, so plants can make better use of what’s already present in your feeding program. The result is steadier, more confident growth when plants are building structure and foliage.

Algen Extract is made from Norwegian sea kelp (Ascophyllum nodosum) and is produced using cold water extraction to help preserve its naturally occurring compounds. It’s described as containing active enzymes and cytokinin, plus amino acids, alongside a broad spectrum of macro nutrients and micro nutrients. Those seaweed-derived components are often sought out as a kelp additive for growers who want more complete, plant-supportive nutrition beyond a basic base nutrient alone.

In the garden, the benefits show up in visible plant vitality rather than complicated features. Algen Extract is positioned to support vigorous vegetative growth, promote a vigorous root zone, and improve trace element uptake through stronger root hair development. It’s also noted for helping maintain better leaf colour, which is a practical sign that plants are staying on track during key growth periods.

For clean, no-nonsense use in modern setups, Algen Extract is formulated without dyes or synthetic growth regulators. It’s also presented as a good fit for soil and coco substrates, making it a straightforward seaweed supplement option for growers who run either of those media and want a kelp-based root zone supplement that aligns with vegetative and early bloom timing.

This is a good fit for growers who want a kelp-focused additive that supports root development, nutrient uptake efficiency, and healthy vegetative growth in soil or coco, without turning the routine into a science project.
