HOW TO INCREASE YIELD? FERTILIZERS AND BOOSTERS (Part Four)

The cultivation of cannabis other than industrial hemp is prohibited in Poland. The cultivation of industrial hemp requires an appropriate permit. By reading this text, we assume that you possess such permission or intend to obtain it before starting any cultivation.

Fertilizers are another key element in maximizing yield. They have a massive impact on the taste, potency, quantity and aroma of the final product.

There are many ways to classify fertilizers used in cannabis cultivation, but we use a practical division aligned with real-world application:

• Base nutrients – NPK

• Boosters and stimulators for flowering and roots

• Vitamins, amino acids, micronutrients

• Mycorrhiza, bacteria and sugars

• Enzymes

Base nutrients – foundation of every grow

Base nutrients, also known as NPK fertilizers, are the foundation of any cultivation project.

They contain the fundamental macronutrients:

• N – nitrogen (growth, leaves, plant structure),

• P – phosphorus (roots, blossom),

• K – potassium (flower mass, taste, resistance).

They are most often sold separately for the phases:

• vegetation, e.g. Canna Terra Vega, Hesi TNT, Micro/Grow – Advanced Nutrients

• flowering, e.g. Canna Terra Flores, Hesi Bloom Complex, Bloom – Advanced Nutrients

They are also divided into:

• organic (bio) – slower action, better taste and aroma,

• mineral – fast action, high yield potential.

They are the absolute minimum required to start cultivation.

Flushing — removing excess nutrients

Flushing means watering the plants only with pure water, without fertilizers, in the final phase of cultivation.

It is crucial for:

✔️ taste,
✔️ aroma quality,
✔️ smooth burning of the dried flowers.

The minimum number of waterings required to achieve this effect is 3, the maximum is usually 8.

Boosters – root and flowering stimulators

Root boosters support:

• the development of root mass,

• nutrient uptake,

• plant resistance.

They are applied from early vegetation to the beginning of flowering.

Flowering boosters work completely differently — they often determine whether your harvest will be mediocre or impressive.

They usually contain high concentrations of P and K, natural stimulants and phytohormones. The effects can be seen in just a few days.

The most popular are:

• Atomic Bloom Bastic

• Plagron Green Sensation

• Hesi Boost

• Canna Boost

The first two are complete boosters (contain P+K), while the others require PK 13/14 to be added.

Ideal beginner combo:

GROW, MICRO and BLOOM from Advanced Nutrients + Atomic Bloom Bastic

(This is a set that really works.)

Vitamins, amino acids and micronutrients

Vitamins are natural additives. Opinions on them vary — some growers see clear benefits, others find them unnecessary.

Recommended:

• Hesi SuperVit

• Plagron Vita Race

• B-52 Advanced Nutrients (boosts aroma — dose carefully!)

Amino acids are useful after the vegetative period and at early flowering.
They do not create a visually spectacular effect, but help increase flower mass.

Example:

• Big Bud – Advanced Nutrients

Micronutrients and CalMag (calcium + magnesium) are especially needed when:

• using strong LED lights,

• growing in coco substrates,

• dealing with rapid growth.

Cal/Mg deficiencies occur most frequently in these cases.

Mycorrhiza, bacteria and sugars — the root magic

Mycorrhiza are symbiotic fungi that:

• protect roots,

• increase plant resistance,

• accelerate nutrient absorption.

They are indispensable in AutoPot systems, coco grows and organic cultivation.

Recommended:

• Mycotrex (BioTabs)

• Piranha (Advanced Nutrients)

Bacteria:

• Bactrex (BioTabs)

• Tarantula (Advanced Nutrients)

With them, plants can tolerate 30–34°C without stress symptoms.

Sugars help:

✔️ stimulate flowering
✔️ increase resin production
✔️ feed bacteria and mycorrhiza

Recommended:

• Carboload

• Bud Candy (sugars + magnesium = stronger scent and taste)

They are used throughout the flowering period and are highly cost-effective.

Enzymes — silent heroes of cultivation

Enzymes:

• decompose dead organic matter,

• protect roots from rot,

• enable reuse of coco substrate,

• increase nutrient uptake efficiency.

They are very useful at higher EC levels and with more additives.

If your aim is maximum yield — use enzymes.
