General Hydroponics MaxiGro 10-5-14 - 16lb

Water-Soluble Dry Concentrate for the Vegetative Stage, 16lb

Seedlings, cuttings, and young plants need a complete nutrient base as they establish roots and foliage, and blending one from raw salts adds a variable most growers would rather avoid. General Hydroponics MaxiGro 10-5-14 is a water-soluble, pH-buffered dry concentrate built as a stand-alone vegetative-stage feed for hydroponic and soil-based crops.

The 16lb size gives larger gardens and small commercial grows enough concentrate for an extended vegetative feeding schedule.

Key Features & Benefits

• Complete Nutrient Profile — supplies primary, secondary, and micronutrients in one dry concentrate
• pH-Buffered Formula — supports stable feeding pH once mixed into water
• Water-Soluble Concentrate — works in hydroponic, soilless, and soil-based systems
• Vegetative-Stage Formula — proportioned to support seedlings, cuttings, and young plants

Who Should Use MaxiGro

Growers starting seedlings and cuttings who want a stand-alone dry concentrate for the vegetative stage, in hydroponic or soil-based setups, will find MaxiGro sized for that early growth phase.

About General Hydroponics

General Hydroponics traces back to 1976 and founder Lawrence Brooke's original work in a Berkeley, California garage, and has operated under the Hawthorne Gardening Company brand portfolio, a Scotts Miracle-Gro subsidiary, since April 2015.

Frequently Asked Questions

What growth stage is MaxiGro formulated for?

It is formulated for the vegetative stage, supporting seedlings, cuttings, and young plants as they establish root and foliage growth. The nitrogen-forward 10-5-14 ratio favors that early structural development.

How much MaxiGro should I use when transplanting seedlings?

Follow the feeding chart's seedling and cutting dosage, which calls for a lighter concentration than the rate used for established vegetative plants. Ramping up gradually as plants mature reduces the risk of stressing young root systems with too strong a solution.

Is MaxiGro a stand-alone fertilizer or part of a larger system?

It is designed as a stand-alone feeding solution, though many growers pair it with MaxiBloom as an optional two-part system covering the full grow cycle. Used alone, it still supplies a complete vegetative-stage nutrient profile.

Does MaxiGro work in soil as well as hydroponics?

Yes, it is water-soluble and works in hydroponic, soilless, and soil-based systems alike. The same dry concentrate dissolves the same way regardless of growing medium.

What is the difference between MaxiGro and MaxiBloom?

MaxiGro is formulated for the vegetative stage at a nitrogen-forward 10-5-14 ratio, while MaxiBloom targets the reproductive stage at a 5-15-14 ratio weighted toward phosphorus and potassium. Growers commonly switch from MaxiGro to MaxiBloom once flowering begins.
