Anyone who wants to grow strong, resilient and high-yielding plants can't avoid getting the nutrient supply right. Fertilizer is the foundation of healthy plant growth, whether in indoor growing or classic gardening. It makes no difference whether you work with soil, coco or hydroponics – every plant needs a balanced ratio of macro- and micronutrients. Modern brands such as Advanced Nutrients, BioBizz, DutchPro or Canna offer advanced solutions tailored to the different growth phases. Even important aids such as cutting powder belong to the wider field of plant care, since they play a decisive role in propagating cuttings.
Plant nutrients decide how well your plants turn light into growth and flowers. In this collection you'll find base nutrients, boosters, root stimulators, enzymes, pH regulators and growing media from brands like Advanced Nutrients, BioBizz, DutchPro, Plagron, Atami, Athena, Canna, Bionova and GEN200. Whether you grow in soil, coco or hydro, there is a line that fits your setup.
How to choose the right nutrients
Start with your medium. Soil lines are usually milder and often organic, while coco and hydro nutrients are formulated as A+B components so calcium and other elements stay available. Next, look at the phase: grow nutrients carry more nitrogen for leafy growth, bloom nutrients shift towards phosphorus and potassium for flower formation. Boosters, PK additives and enzymes are optional extras you add on top of a solid base, not a replacement for it.
Feeding with control
Stick to one brand's schedule where possible, start below the recommended dose with young plants and measure EC and pH every time you mix a new tank. A reliable meter from our pH & EC meters takes the guesswork out of it. For a full overview of phases, ratios and common mistakes, read our complete feeding guide.
Questions & answers about Nutrients
All growing questions →- Nutrients Which nutrients do I need for growth and flowering? A two-part grow/bloom base (or one brand's A+B) from one manufacturer is enough for most grows. Add Cal-Mag if you grow in coco or use so... Read the answer →
- Nutrients How much nutrient should I give per litre? Base nutrients usually land between 1 and 5 ml per litre per part, depending on brand, stage and medium. Never go over the label, and in ... Read the answer →
- Nutrients When do I switch to bloom nutrients? Around the time you switch to 12/12 light, or once the first flower sites show, usually 1–2 weeks after the flip. Your brand's chart give... Read the answer →

Why Fertilizer Is So Important
Plants need nutrients to carry out photosynthesis, develop roots and form flowers or fruit. In natural soil these nutrients are only available in limited amounts and are used up quickly under intensive cultivation. Without additional feeding, deficiency symptoms appear in the form of yellow leaves, weak growth or low yields.
A high-quality fertilizer specifically delivers the substances plants need at each stage of development:
Growth phase: nitrogen (N) for strong leaves and stems. Flowering phase: phosphorus (P) and potassium (K) for flower formation and fruit set. Micronutrients: iron, magnesium, zinc and others for a stable immune system.
Types of Fertilizer
Organic Fertilizers
Brands such as BioBizz or Guanokalong rely on natural ingredients like compost, bat guano or algae. These products not only improve nutrient supply but also soil structure and the microbiome.
Mineral Fertilizers
Advanced Nutrients, Canna, DutchPro or Hesi stand for high-performance mineral fertilizers that deliver nutrients in precisely calculated form. The result: fast growth and high yields, ideal for indoor growing or hydro systems.
Specialty Fertilizers & Additives
Products from Aptus, Atami, GEN200, Plagron, Plant Mechanics, Plant Revolution, Rock Nutrients or Superthrive provide targeted additives: from enzymes to boosters to root stimulators that get the most out of every plant.

DutchPro: simple, efficient nutrient solutions with strong results. Canna: a classic for soil, coco and hydro systems, valued worldwide. Aptus & Atami: innovative additives and boosters for more vitality. GEN200: specialty products for resilience and better nutrient uptake. Guanokalong: guano-based fertilizers for ecologically minded growers. Hesi: the value-for-money hero, especially popular with hobbyists. Plagron: a broad range from soil to additives. Plant Mechanics & Plant Revolution: innovative products for root growth and mycorrhizae. Rock Nutrients: strong boosters and additives for professionals. Superthrive: a cult product with vitamins for plant health.
Using Fertilizer in Indoor Growing
With indoor cultivation in grow tents, precision is essential. Since plants grow in a closed system, they have no access to natural resources such as rain or soil life.
Exact dosing: avoid over- or under-fertilizing. Adjusting to the phase: growth = more nitrogen, flowering = more phosphorus and potassium. Water quality matters: many fertilizers are formulated for soft or hard water.
Complete sets are particularly practical, with brands like BioBizz or Canna offering coordinated nutrient packages for every phase.
Accessories for Successful Plant Fertilizing
Alongside liquid or powder fertilizers, accessories play a central role:
Cutting accessories: clean tools are important for cuttings and young plants. Cutting powder: promotes root formation on freshly cut cuttings. Propagation cubes & plugs: give cuttings a stable base and optimal moisture. Starter blocks for cuttings: ideal for the first growth phase, before plants are moved into larger pots.
This accessory range perfectly complements a fertilizing strategy, as it directly supports the propagation and vitality of young plants.
Fertilizer in Outdoor Gardening
Plants outdoors also benefit from targeted fertilizing. Vegetable beds, fruit trees and ornamental plants need regular nutrient feeding to reach their full potential. While indoor growers often rely on mineral fertilizers, organic products such as Guanokalong or BioBizz are very popular outdoors. They improve soil quality in the long term and are environmentally friendly.
Tips for Correct Fertilizing
Know your plant's needs: every plant has different nutrient requirements. Watch the dosage: follow manufacturer guidelines closely and avoid over-fertilizing. Check regularly: observe the leaves – yellow leaves can indicate nitrogen deficiency, brown edges a potassium deficiency. Keep an eye on pH: nutrients can only be absorbed at the right pH value. Combine products: main fertilizer plus additives for maximum results.
