The General Hydroponics MaxiGro 16lb is an extremely potent, stand-alone, water-soluble dry concentrate nutrient specifically formulated to encourage rapid vegetative growth from seedling through the end of the veg stage. With a 10-5-14 NPK ratio, General Hydroponics MaxiGro delivers a complete primary, secondary, and micronutrient profile in a pH-buffered formula that stimulates vigorous growth of seedlings, cuttings, and established plants across a wide variety of crops in both hydroponic and soil-based environments.
The 16lb size of General Hydroponics MaxiGro is the ideal mid-volume option for serious home growers and small commercial operations who need more than the 2.2lb can provide but aren’t yet running at the scale of the 50lb bulk bag. Part of the Maxi Series alongside MaxiBloom™ — use General Hydroponics MaxiGro from seedling through the vegetative stage, then transition to MaxiBloom™ at the onset of flowering for a simple, highly effective two-product feeding program.
