Intro

Choosing a feed chart is easier when you start with how you grow. General Hydroponics offers several nutrient programs because growers have different goals, systems, and levels of control. Some growers want a simple one-bottle-per-stage program. Others want the flexibility to fine-tune nutrition every week. Commercial growers may need water-soluble powders for injectors and stock tanks.

This guide helps growers choose the best GH feed chart based on product line, growing medium, system type, and comfort level.

Start with your product line

Flora Series is the classic three-part liquid base nutrient system: FloraMicro, FloraGro, and FloraBloom. It is best for growers who want flexible control over plant nutrition from vegetative growth through flowering.

FloraNova is a powerful one-bottle-per-stage liquid base nutrient system. Use FloraNova Grow during vegetative growth and FloraNova Bloom during flowering.

FloraPro is built for commercial growers and controlled-environment agriculture. It uses water-soluble fertilizers designed for stock tanks, day tanks, and injector systems.

Maxi Series is a dry, water-soluble nutrient line with one product for vegetative growth and one product for flowering.

BioThrive Grow and BioThrive Bloom are a good fit for soil-style growing and gardeners who prefer the General Organics family.

Choose by experience level

Beginner growers should start with a simpler program such as FloraNova 1-Part, Flora Series 3-Part, Maxi Series, or BioThrive Grow and Bloom.

Intermediate growers may choose Flora Series 6-Part, FloraNova 4-Part, Maxi Series with selected supplements, or BioThrive with BioRoot, BioBud, or CaMg+.

Advanced or commercial growers may benefit from Flora Series 10-Part, FloraNova 8-Part, FloraPro Standard, or FloraPro High EC programs.

Choose by grow medium

Most GH feed programs work well in hydroponic systems. Flora Series, FloraNova, FloraPro, and Maxi Series are especially relevant for liquid-feed hydroponic programs.

Coco and soilless media often need close attention to calcium, magnesium, EC, and pH. Programs using CALiMAGic or CaMg+ may be useful depending on water quality and crop needs.

For soil-style growing, many growers choose BioThrive, Maxi Series, FloraNova, or Flora Series depending on how much control they want.

Choose light, medium, or aggressive schedules

Use light feed if plants are young, sensitive, newly transplanted, or if the grower wants a conservative starting point.

Use medium feed when plants are healthy, actively growing, and the environment is stable.

Use aggressive feed only when plants are vigorous, light intensity is high, and the grower monitors EC, pH, and plant response closely.

Final recommendation

The best GH feed chart is the one that matches the system, skill level, and desired amount of control. New growers should start simple. Experienced growers should choose a program with the precision they need. Commercial growers should choose a program designed for scale and repeatability.
