Bloom City Professional Cal-Mag Fertilizer, 1/2 Pint

From the brand Grow The Love, we're a small team of botanists and plant chemists dedicated to creating healthy, sustainable nutrients for your garden. Bloom City's formulations are better for plants, people, and the planet, offering conscientious growers a clean and simple alternative to Big Ag fertilizers.

We created a line of Plant Nutrients supplements that provide essential nutrients and organic compounds plants need to grow strong. Big fertilizer firms use harmful, outdated chemicals that are bad for people and the planet, but Bloom City's nutrient systems offer craft growers a safe solution for large, clean blooms.

Bloom City's unique formulas and probiotics generate high-quality yields without the low-quality, filler ingredients of other brands. Our sustainable fertilizers use many organic ingredients like wild Atlantic kelp, fish bone meal from the Pacific Northwest, and solar-evaporated potassium rather than industrially mined, all sourced in the USA.

From houseplants to hydroponics, our nutrient systems have what you need for beautiful, healthy growing. Our products offer multiple applications for pots, garden beds, and foliar spray, with precise nutrition for every stage of growth.

Our Cal-Mag, pH Up, pH Down, Organic CleanKelp, Silica Boost, and Organic Foliar Spray products are all highly rated by customers, with an average of 4.6 out of 5 stars across over 14,000 reviews. These products are designed to improve plant health, optimize mineral intake, promote root and shoot growth, strengthen cell walls, and enhance nutrient absorption.

Bloom City gives the power of clean, regenerative gardening to the home grower with full-spectrum plant nutrition for bountiful yields in any growing environment. Our emphasis on environmentally responsible production methods with natural and sustainable input sourcing makes for more bio-available nutrient outputs and safer, cleaner gardens. Bloom City's nutrient systems are everything you need to grow lush, beautiful gardens without harsh chemical fertilizers.
