    removes the guesswork

    Fast growing annuals typically require high amounts of Calcium, especially during flower production. Most forms of Calcium in typical fertilizers also supply high amounts of Nitrogen, which can inhibit flowering and cause unwanted leafy growth. Commercial Cal combines two forms of soluble Calcium in a precise ration with reduced Nitrogen, resulting in the perfect Calcium additive to produce the flowers you demand.
