    Concentrates is my go-to for seed starting supplies and organic amendments of every kind. As a small-scale grower of cut flowers, veg, and fruit, i am always super pleased with the quality of customer service, as well as my purchases. in addition, the prices always seem to be better than competitors. Concentrates is a one stop shop to get the season started off right!

    Great product for establishing trace minerals in inert substrate such as coir or peat. Also boosts water retention a bit. Great product.
