What nutrient and substrates to choose for a beginner in indoor growing

When starting out in cultivation, whether for indoor or outdoor plants, choosing the right nutrient and the right substrate is essential to achieve good results without too much difficulty. Some nutrient 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 cultivation management. This article guides you towards the most accessible solutions to start off smoothly.

2. The nutrient suitable for beginners

2.1. Nutrient organic fertilizers

Organic nutrient are often recommended for beginners because they allow for gradual fertilization without the risk of overdose. 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 provides nutrients suitable for growth and flowering without the need to adjust the pH. Easy to apply, it allows for a gradual assimilation of nutrients.

• Biobizz : Renowned for its 100% organic approach and its nutrient that are easy to dose like Bio-Grow and Bio-Bloom. It promotes the development of the root system and improves nutrient absorption.

• Biotabs : Offers nutrient in the form of tablets to be incorporated directly into the substrate, greatly simplifying fertilization. Ideal for a self-sufficient cultivation without frequent watering of nutrient.

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

Mineral nutrient offer quick nutrient absorption, but some are easier to use than others. These are perfect for a first try without hassle:

• Hesi : An easy-to-use range with nutrient enriched with trace elements for optimal absorption. Its gentle formulation helps avoid the risks of overdosage. The Pro Line TNT Grow is optimal for the early days of the plant, as well as for the entire growth period, not to mention the Pro Line Bloom, which is optimal for growers who do not want to risk over-fertilization.

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

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

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

2.3. Nutrient techniques requiring more attention

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

• Aptus : Very concentrated, it requires careful dosing and strict monitoring of pH and EC. Designed to maximize yield, it necessitates a methodical approach. Among their flagship products, we find the growth stimulator StartBooster which is very effective for stimulating roots and boosting growth, then there is the nutrient fertilizer TopBooster, which will be used in small doses so as not to over-fertilize 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 a high precision in dosing and a rigorous monitoring of parameters. This range of nutrient is highly valued by growers seeking optimized production.

• Mills Nutrients : Very concentrated, providing 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 the 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 nutrient (depending on the variety grown).

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

• 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 nutrient.

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

3.2. Mineral substrate: a feasible alternative

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

• Light-Mix by Biobizz : Less enriched than the All-Mix, it allows for better control of the supply of nutrient.

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

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

• Mills Lightmix Light mineral substrate offering good drainage and easier nutrient management.

• Gold Label Special Mix : A high-end substrate 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 soil allowing for effective assimilation of mineral nutrients.

3.3. Culture in coco: an intermediate level

The culture in coco is situated between soil and hydroponics. It offers a rapid growth and good root oxygenation, but requires strict monitoring of pH and EC. It is better to watch and read tutorials before starting a first cultivation.

• Coco Premium by Canna : A neutral substrate that requires regular nutrient input.

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

• Coco Mills Ideal for precise and high-performing cultivation.
