Understanding Plant Nutrients: The Essentials and Additives

Cultivating plants can be an incredibly rewarding hobby, but to grow vibrant and healthy plants in hydroponics systems, you will need to supply them with the essential nutrients they require to grow.

In this blog post, we will shed some light on the basics of plant nutrition, we will be focusing on the 'base formulas' that contain the essential NPK elements, and we will explore some of the various additives like root boosters, bud boosters, PK boosters, and calmag supplements 

Sound like something you are interested in? Lets jump into it...

Base Nutrients, The Building Blocks 

To ensure your plants receive the essential NPK elements in the right proportions, gardeners use 'base formulas.' These formulas are carefully designed to provide the fundamental nutrients plants need for optimal growth. They are available in two forms, liquid and granular which makes it easy to find something that will suit your specific gardening needs.

Nitrogen (N)

Nitrogen is crucial for plant growth, as it aids in the development of leaves and stems.

It's a vital component of chlorophyll, the pigment that helps plants convert sunlight into energy through photosynthesis.

A deficiency in nitrogen can result in stunted growth and yellowing of leaves.

Phosphorus (P)

Phosphorus plays a central role in root development and flowering.

It's essential for energy transfer and the formation of DNA and RNA.

A lack of phosphorus can lead to poor root development and reduced flower and fruit production.

Potassium (K)

Potassium is essential for overall plant health, helping with disease resistance and water uptake.

It aids in the regulation of various plant processes, including the opening and closing of stomata.

A deficiency in potassium can result in wilting, brown leaf edges, and poor fruit quality.

Plant Additives - The Cherry On top 

Now, let's explore some plant additives - these are not essential but can take your gardening experience to the next level

Root Boosters

Root boosters can contain anything from growth hormones to vitamins to beneficial microbes and they are generally designed to protect your roots & stimulate root development.

Root boosters help plants establish strong, healthy root systems, enhancing nutrient uptake and overall vitality.

Bud Boosters

Bud boosters are normally high in phosphorus and potassium but they usually also contain ingredients like amino acids, carbohydrates or even PGR's (plant growth regulators). PGRs can be from natural sources such as guano or they can be synthesized in labs. 

Bud boosters can promote larger and more abundant blooms but the main function or boosters is to increase flavour, oils and terpenes.

PK Boosters

PK boosters are specifically designed to provide an extra dose of phosphorus and potassium during the flowering stage.

Pk Boosters maximize the plant's ability to produce flavorful fruits/flowers and can contribute towards to heavier, more dense fruits/flowers 

Enzyme-Based Products

Enzyme-based products contain natural enzymes that help break down organic matter, improving nutrient absorption and digesting old root material.

They enhance soil health and increase nutrient availability, leading to healthier, more vigorous plants.


Cal-Mag supplements provide essential calcium (Ca) and magnesium (Mg).

Cal-Mag helps to prevent deficiencies, improve overall plant strength and enhance cell structure. 

Most cal-mag supplements contain alot of nitrogen which is why some companies suggest using cal-mag as a vegetive booster.


Whether you're growing flowers, fruits, or vegetables, providing your plants with the right balance of nutrients and can make a significant difference in their health, growth, and the quality of the produce.

Much like humans, different plants and cultivars respond in their own unique ways. Experimenting with different additives and observing their effects can be an exciting journey for any gardener looking to maximize their plant's potential.
