Which nutrients and substrates to choose for a beginner in indoor growing

When starting out in cultivation, whether for indoor plants or outdoor, choosing the right fertilizer and the right substrate is essential to achieve good results without too much difficulty. Some fertilizers are designed to be easy to use, while others require precise dosing and strict monitoring of pH and EC (electrical conductivity). Similarly, the choice of substrate plays a crucial role in nutrient stability and crop management. This article guides you towards the most accessible solutions to start calmly.

2. Fertilizers suitable for beginners

2.1. Easy-to-use organic fertilizers

Organic fertilizers are often recommended for beginners because they allow progressive fertilization without risk of overdosing. They nourish both the plant and the soil, promoting healthy growth.

• Plagron : Ideal for beginners with its organic range "Alga Bloom and Alga Grow". It offers nutrients adapted to growth and flowering without the need to adjust pH. Easy to apply, it allows progressive assimilation of nutrients.

• Biobizz : Known for its 100% organic approach and easy-to-dose fertilizers like Bio-Grow and Bio-Bloom. It promotes root system development and improves nutrient absorption.

• Biotabs : Offers fertilizers in tablet form to be incorporated directly into the substrate, simplifying fertilization to the maximum. Ideal for autonomous cultivation without frequent liquid fertilizer watering.

• Terra Aquatica (GHE) : Provides low-concentration organic fertilizers, suitable for beginners seeking natural plant development. The "Pro Organic" range is particularly appreciated for its simplicity.

• Guanokalong : Used for its simplicity and effectiveness without complex adjustments. Rich in humic and fulvic acids, it improves soil structure and microbial activity.

2.2. Mineral fertilizers

Mineral fertilizers offer rapid nutrient absorption, but some are easier to use than others. These are perfect for a first hassle-free trial:

• Hesi : An easy-to-use range with fertilizers enriched with trace elements for optimal assimilation. Its gentle formulation helps avoid the risk of overdosing. The Pro Line TNT Grow range is optimal for the first days of the plant, as well as for the entire growth phase, and not forgetting the Pro Line Bloom, which is optimal for growers who do not want to risk overfertilization.

• Canna : Offers mineral solutions adapted to different substrates with stable formulas. Canna Terra is particularly recommended for beginners growing in soil.

• Green House Powder Feeding : A convenient option with its ready-to-use powder fertilizers, perfect for effective nutrition without complex adjustments. Easily dosed, it is suitable for growth and flowering cycles. A growing schedule is available HERE.

• Advanced Nutrients : Designed to offer an automatic pH regulation system, simplifying the process for beginners. It also contains additives beneficial for roots and plant growth.

2.3. Technical fertilizers requiring more attention

Some fertilizers are intended for experienced growers due to their high concentration and the precision required for dosing. They are effective but not well suited for beginners.

• Aptus : Highly concentrated, it demands careful dosing and strict monitoring of pH and EC. Designed to maximize yield, it requires a methodical approach. Among their flagship products is the StartBooster growth stimulator which is very effective for stimulating roots and boosting growth, then there is the TopBooster flowering fertilizer, which should be used in small doses to avoid over-fertilizing your plants.

• Athena : Designed for high-precision cultivation, often used in hydroponics or with advanced fertigation systems. It offers total nutrient control, ideal for experienced growers.

• House & Garden : Requires precise dosing and rigorous monitoring of parameters. This range of fertilizers is highly valued by growers seeking optimized production.

• Mills Nutrients : Very concentrated, offering optimal performance under strict control. It combines high-quality ingredients to maximize nutrient absorption.

• Emerald Harvest : Specific to experienced growers seeking maximized yields. Its use requires rigorous monitoring of plant needs according to growth phases.

3. Substrates for beginners

3.1. Organic soil: the simplest solution

Organic soil is ideal for beginners because it already contains natural nutrients that facilitate plant growth without requiring complex adjustments. It offers good water retention and improves soil structure.

• Plagron Allmix : A very good soil, it promotes vigorous growth and you can grow tomatoes without adding fertilizer (depending on the variety grown).

• Biobizz All-Mix : Contains beneficial microorganisms for balanced organic cultivation.

• Canna Bio Terra Plus : A substrate specially designed for organic cultivation with an airy texture.

• BAC Lava Soil : Soil enriched with volcanic minerals, ideal for robust growth and good moisture retention.

• Mills Organic Lightmix : A light and airy substrate, perfect for growers using organic fertilizers.

• Premier Tech - Pro-Mix HP : A high-quality soil with excellent aeration and optimal drainage. Although it is more expensive than other substrates, it offers a higher yield thanks to its mycorrhiza-enriched composition, promoting optimal nutrient absorption and vigorous growth

3.2. Mineral soil: a feasible alternative

Mineral soil is also a good option for beginners, although monitoring pH and EC may be necessary to optimize cultivation.

• Biobizz Light-Mix : Less enriched than All-Mix, it allows better control of mineral fertilizer input.

• Canna Terra Professional : Ideal for crops requiring rapid nutrient absorption.

• Plagron Grow Mix : A good compromise for those who want an enriched but controllable base.

• Mills Lightmix : A light mineral substrate offering good drainage and easier nutrient management.

• Gold Label Special Mix : A premium potting soil designed for optimized cultivation with a good air/water balance.

• Atami Janeco-Light Mix : A stable and pre-fertilized substrate, ideal for beginners.

• Bionova Soilmix : A balanced potting soil allowing efficient mineral nutrient uptake.

3.3. Coco cultivation: an intermediate level

Cultivation in coco is between soil and hydroponics. It offers rapid growth and good root oxygenation, but requires careful monitoring of pH and EC. It is better to watch and read tutorials before starting your first grow.

• Coco Premium de Canna : A neutral substrate that requires regular nutrient supply.

• Coco Gold Label : A high-quality substrate with excellent water and air retention.

• Coco Mills : Ideal for precise and high-performance cultivation.
