Algen Extract

House & Garden Algen Extract is a seaweed-derived growth stimulator made from Ascophyllum nodosum — one of the most nutrient-dense seaweed species available. Extracted from this fast-growing marine plant, Algen Extract contains large amounts of the micro and macro nutrients needed for vigorous plant growth alongside very high levels of natural plant hormones including cytokinins, gibberellins, and auxins.

Algen Extract is specifically designed for use during the growth phase, starting when root systems are well established. Its natural hormone content stimulates root branching, new shoot development, and overall plant vigor — creating faster vegetative growth and healthier plants heading into flower. Micro nutrients, micro-biology, and macro-nutrients are all present in the formulation.

Apply throughout the growth phase as a root-zone drench or in the nutrient solution. Compatible with all growing media. Part of House & Garden's premium additive lineup, Algen Extract works alongside their Cocos or Aqua Flakes base nutrients for growers building the full H&G system.
