Plant Tonic is made from the fast-growing tips of the Giant Pacific Kelp Plant from the cold, pristine and secluded waters of coastal British Columbia. This giant kelp is the fastest growing plant known, growing up to 3 feet per day! Harvesting takes place in late spring and again in early fall (to protect indigenous species). Only the actively growing portion of the plant-the top 2 to 4 metres-is selected.
One bottle makes 20 litres of fertilizer.
