House & Garden Nitrogen Boost

Nitrogen Boost is a highly concentrated nitrogen additive from House & Garden. It's perfect for large, high-nutrient plants. Compatible with all soil and hydroponic applications, this powerful dose of nitrogen ensures your plants have vigorous leaf growth and stronger stems for higher yields later in the flowering period. This product should be used throughout the vegetative phase and during the first half of the flowering period. Disclaimer: Nitrogen Boost works in all growing media and contains no dyes, synthetic PGRs, or detectable heavy metals. To maximize activity and shelf life, sealed bottles and containers should be stored between 45 and 85 degrees Fahrenheit (7 to 29 degrees Celsius) and used within one year of breaking the seal.
