8 oz. liquid bloom-boosting fertilizer from Superthrive (formerly Dyna-Gro). 3-12-6 formula (3% nitrogen, 12% phosphorus, 6% potassium). Includes micronutrients and trace elements. Contains no urea. Use when extra blooms are desired, before exhibition or a special event, for example. Though very effective when used when needed, we don't recommended for continual use (the all purpose 7-9-5 formula better for this). Use at rate of 1/4 to 1/2 tsp. per every gallon of water. Sorry, we cannot ship fertilizer on international orders.
