HESI HousePlant Elixir is the most versatile choice for a mixed indoor collection. It provides complete nutrition in a low-salt formula suitable for soil, coco and mineral growing systems.

Use approximately 2 ml per litre for slower-growing plants and 3 to 5 ml per litre for faster growth, adjusting frequency according to light, temperature and water use.

Plants growing in lower light require less fertiliser because their growth and nutrient demand are reduced.

HousePlant Elixir is the simplest general-purpose choice for houseplants in semi-hydroponic systems.

For a more specialised hydroponic programme, use Hydro Growth during vegetative development and Hydro Bloom for actively flowering plants.

Monitor pH and electrical conductivity because mineral systems provide less buffering than an organic substrate.

HESI TNT Complex is designed for vegetative growth in soil and coco-based substrates.

HESI Bio Grow is the plant-derived, vegan alternative for growers who prefer a biologically based fertiliser.

HESI HousePlant Elixir remains the easier all-purpose option when you want one product for a varied houseplant collection.

These are targeted supplements rather than replacements for a complete fertiliser.

HESI Root Complex supports young plants, new roots and recovery after repotting or stress.

HESI PowerZyme helps break down dead organic root material and is most relevant in established or reused growing media.

HESI SuperVit is an ultra-concentrated supplement used in very small quantities.

Use a supplement when it addresses a specific need. Adding every product does not automatically produce better growth.

A base fertiliser may be combined with compatible supplements, but do not combine several complete base fertilisers in the same solution.

HousePlant Elixir is designed as a broad all-purpose formula. TNT Complex, Bio Grow and Hydro Growth should be treated as alternative base fertilisers selected according to the growing system.

Prepare the water first, add each product separately and mix between additions.

For most plants in an organic substrate, careful dosing and observation are usually more important than constant EC adjustment because the growing medium provides some buffering.

In semi-hydroponics and hydroponics, pH and EC provide valuable information about nutrient concentration and availability.

Measure the finished solution after adding fertiliser, then adjust the pH only if necessary using appropriate HESI pH Plus or pH Minus.

Never mix concentrated pH corrector directly with fertiliser concentrates.
