## Description

Made by experienced cannabis growers and lobster trappers on an island off the coast of Maine, this Cold-Water Extracted Kelp is a multipurpose biostimulant, plant food, and soil conditioner that is a staple in any organic living soil or hydroponic garden throughout all stages of growth.

## Features

- Extend the Freshness and Life of Your Christmas Tree! Needles Stay Longer and Smell is Preserved. Great for: seed soaking, cloning, transplants, compost teas. For use in soil and hydroponic gardens in all stages of growth.
- WHY KELP? Norweigan Kelp (Ascophyllum nodosum, or seaweed) is one of the fastest growing plants in the world and contains a vast array of naturally-occurring: macro and micro nutrients, antioxidants, vitamins, minerals, hormones, enzymes, and microbes that will benefit any plant. Kelp Extracts are Generally Approved for Organic Farming by the NOP.
- HOW IT’S MADE: Kelp is sustainably harvested by our friends in Stonington, Maine. This remote island is surrounded by some of the purest water on the Atlantic coast and is home to a diverse community of marine life and dense kelp forests. The kelp is submerged in fresh water and aerated to assist in the extraction process.
- WHY COLD-WATER EXTRACTED? The aerated cold-water extraction process allows us to craft a truly all-natural, pH neutral, potent extract that is shelf-stable with only two ingredients: kelp and water. Other kelp extracts rely on chemicals such as potassium hydroxide to accelerate the extraction process or phosphoric acid for shelf stability and to adjust pH.
- WHAT’S A BIOSTIMULANT? A substance or micro-organism that, when applied to seeds, plants, or the rhizosphere, stimulates natural processes to enhance or benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, or crop quality and yield.
