H+G NitroGEN 1L

Nitrogen Boost is carefully formulated to provide plants with optimal levels of nitrogen during their vegetative cycle. Nitrogen plays a key role in many processes and is used by the plant to form proteins, hormones, vitamins, enzymes, and chlorophyll. Chlorophyll is the green plant pigment that captures light energy for use in photosynthesis. Increasing the availability of nitrogen can produce bigger yields, tastier vegetables, and a crop that is more resistant to pests, diseases, and adverse conditions.

Symptoms of a nitrogen deficiency include a dramatic reduction in size and quality of the overall yield.  Older leaves become pale green or yellow, beginning in the tips of the lower leaves and eventually spreading throughout the plant. Plants become spindly and overall growth slows.  In extreme deficiencies, the affected leaves will become brownish, wither, die and hang down around the lower stem.

To provide your plants with the nitrogen they require, add Nitrogen Boost to your feeding schedule today. Nitrogen Boost promotes vigorous plant growth, increasing seed and fruit production and improving the size and quality of the overall harvest.  Your garden will immediately look greener and healthier with the additional levels of nitrogen available to the plant.



Nitrogen Boost can be applied up to the third week of flowering, starting with 1 ml per gallon on younger plants and progressing upwards to 2 ml per gallon.  For aggressive plants, these amounts can be doubled (starting with 2 ml and ending with 4 ml).  Rates needed to achieve different yields with different crops may vary. Refer to the feeding chart for detailed usage instructions.


Nitrogen Boost is extremely concentrated and overuse can “burn” plants and damage leaves.  Immediately flush plants with clean water at the first sign of nutrient burn.
