Get the same trusted blend with added bulk savings in convenient 5 lb and 20 lb options. Prime2Bud™ 4-6-4 draws its power from the amino acid Arginine, a precursor to Polyamines. Polyamines have a vast array of beneficial effects within the plant such as bud induction, flower and fruit development.

Polyamines are important messengers involved in almost all physiological and biochemical processes, growth & development, and adaptation of plants to stress.
