🌱 Why Ascophyllum Nodosum?
Ascophyllum nodosum is a cold-water seaweed sustainably harvested from the North Atlantic — and it’s one of the most powerful natural tools in any grower’s arsenal.
At Seeweed Collective, we use a fine, water-soluble powder made from dried Ascophyllum nodosum to support healthy plant growth from root to canopy — whether you’re tending vegetables, flowers, or a few legal cannabis plants at home.
✅ Natural Benefits for Soil and Plants:
🧬 Root Support
Packed with natural plant hormones like cytokinins and auxins, Ascophyllum helps encourage strong, healthy root systems — ideal for young plants and transplant recovery.
💧 Improved Nutrient Uptake
This seaweed contains organic compounds like mannitol and alginates that help your plants better absorb essential nutrients, including nitrogen, magnesium, and phosphorus.
🛡️ Stress Resistance
Supports plant resilience against environmental stress like heat, drought, and transplant shock. Many growers notice better recovery and stronger growth under variable conditions.
🌿 Soil Structure & Microbial Activity
Alginic acid helps retain moisture in the root zone and supports a thriving soil microbiome — especially useful in organic or living soil systems.
🌸 All-Stage Growth Support
Ascophyllum is suitable for both vegetative and flowering stages. When used alongside our veg and bloom blends, it helps create a complete, soil-friendly feeding system.
