If you want an all-organic one part liquid grow formula, try Dr. Hornby's Iguana Juice Grow, which has been field tested and proven to give exceptional growth during vegetative cycle. The growth during the vegetative cycles was so impressive it came close to equaling the performance of our legendary synthetic master mix formula. And when we put Iguana up against our competitors' one part products, Dr. Hornby's Iguana Juice was totally superior because its exclusive blend of organic compounds encourages strong, dense branching, a large healthy root system, fast growth, that prepares the plant for a spectacular flowering cycle. Dr. Hornby's Iguana Juice contains a fish base from the super clean ice cold waters of the far North Pacific Ocean, plus over 70 minerals, krill extract, yucca extract, earthworm castings, seabird guano and bat guano and alfalfa. Backed by our supersonic performance guarantee.
