Pure Protein Dry (PPD) is a powerful organic fish fertilizer containing amino acids and beneficial enzymes. It is a complete nutrient for plants and microbes with 15-1-1 (15% nitrogen content), high PPM (parts per million) of iron and zinc, rich macro- and micro-nutrients and beneficial microorganisms, and the highest amino acid profile (> 80%) of any organic fertilizer on the market. The codfish hydrolysate is cold processed and freeze-dried into 100% water-soluble powder that can be used with any aeroponic, hydroponic, or drip irrigation system. With the addition of PPD to your current feeding regimen, you can achieve high yields and rapid results without compromising the health of your plants, soil, or customers. Application: For quickest results, apply PPD as a foliar feed (spray the underside of leaves) at sunset or sunrise 2-3 times/week throughout entire growth cycle (vegetative and flowering/fruiting) up until 2 weeks before harvest. For a healthy root system and rhizosphere, apply as a root drench 1-2 times/week throughout entire growth cycle. For an insane compost tea, add 1-2 scoops of PPD to tea during the beginning of the brewing process. For more information and application instructions, see http://www.organicagproducts.com/15-1-1.html
