Product description


It should be used on soil-based media, rather than on soilless media, primarily during warmer months, indoors or in warm-climate regions. These environments allow the roots to take up the nitrogen sources most effectively. Long-term use of high Phosphorus formulas can lead to plant stretch in some plant varieties. Therefore, it is recommended when using this formula over long periods (greater than 3-4 months) of plant growth, alternate with a lower Phosphorous source such as rainwater, calcium nitrate or other lower phosphorus fertilizers.


Can be used as a root drench or foliar spray. 

How to Use

Dissolve the following amounts in 1 gallon of water. An injector should not be used.
1/2 tsp.  =  125 ppm

1 tbsp.   =  750 ppm
