This legendary guano, sourced from uninhabited ancient fossilized deposits, is the "king" of bloom guanos, and considered by the ancients as a "gift from the gods." No other phosphate guano, pound for pound, provides as much "flowering dynamics." Naturally formulated with no nitrogen and high phosphorous to focus the plant's energy on the production of flowers, fruit, and veggies, not on excessive green growth. To experience awesome yields, feed your plants the legendary, Primal Harvest. Available in a uniform 100 mesh powder or 2-4mm pellets for easy, dust free use.
