Nitrogen Boost is House & Garden’s nitrogen supplement. It is perfect for large, heavy feeding plants. It's compatible with ALL soil and hydroponic applications -- this powerful dose of nitrogen ensures that your plants will have vigorous leafy growth and stronger stems to support a heavier yield later in flower. This product should be utilized throughout the vegetative stage as well as the first half of flowering.

In order to maximize activity and shelf life, sealed bottles and containers should be stored between 45 to 85 degrees Fahrenheit (7 to 29 degrees Celsius) and should be used within one year of opening the seal.
