Know before you buy
Yes, MaxiGro is designed to be versatile and performs effectively in both soil-based environments and hydroponic setups.
MaxiGro has an NPK ratio of 10-5-14. This formula is specifically balanced to support vigorous vegetative growth, providing a higher concentration of nitrogen and potassium to encourage strong stems and healthy foliage.
MaxiGro is pH buffered, which helps maintain the nutrient solution within an optimal range for plant uptake. However, it is always good practice to monitor your water's pH levels periodically to ensure they stay within your specific plant's requirements.
MaxiGro is a stand-alone, complete nutrient formula. It contains a full spectrum of primary, secondary, and essential micronutrients, meaning it can support your plants throughout the vegetative stage without the need for additional additives.
Because it is a water-soluble dry concentrate, it is essential to keep the bag tightly sealed in a cool, dry place. Moisture exposure can cause the powder to clump and potentially degrade the nutrient quality over time.
