Humboldt Nutrients Bloom formula was designed in Humboldt County to be used with our Grow and Micro to be a complete growing nutrient system for hydroponics as well as other growing mediums.
Bloom is specifically formulated to improve plant photosynthesis, metabolism, genetics and eventually crop quality and yield. Plant growth, flowering and fruiting depend on the correct balance of Phosphorus and Potassium.
Through extensive research and development, the Humboldt Nutrients team of chemists has formulated an easy to use fertilizing program for use on a variety of vegetables, flowers or herbs. If you want to maximize your results, this is the 3-part base system for you.
Our premium three-part nutrient system leaves nothing to chance and produces excellent high yield crops. When used in conjunction with our high powered additives, Humboldt Nutrients three-part fertilizer program will produce fantastic yields and premium quality crops.
Available Phosphate (P2O5)
Soluble Potash (K2O)
Derived From: Magnesium Phosphate, Phosphoric Acid, Potassium Phosphate and Magnesium Carbonate.
Fill your reservoir with clean water before administering any nutrient or additive. Make sure that the water level in your reservoir is sufficient to effectively flood your desired area or table. Potential nutrient lock-up can be avoided by adding the Micro before the Bloom and Grow.
Always wash your measuring cup immediately after adding and stirring in each nutrient. Never mix any of these nutrients together in their concentrated form. After adding and stirring in each nutrient, check and adjust the pH to between 5.0 and 6.5.
Always check a small sample of water, not the whole reservoir. Not all meters will read identically, Humboldt Nutrients tests are conducted with a Hanna HI9813-0 meter. Keep the water temperature in your reservoir between 66 and 75 °F. Drain your reservoir and pumps at least once a week to prevent any salt build-up. Please avoid storing in direct sunlight and protect from freezing.
