🌱 What nutrients to use in hydroponics? A beginner's guide

What exactly do plants need and how do the nutrients we use in practice work?

Hydroponics is based on the fact that you don't give plants soil, but a precise mix of nutrients in water . Proper nutrition is therefore the basis of all cultivation.
If you use quality fertilizers, plants grow faster, are stronger and have better taste.

In this article, we will explain what nutrients plants need , how to dose them , and also how specific Hesi products work, which have also proven themselves in home hydroponics.

🧪 What do plants need in hydroponics?

Everything rests on two groups of elements:

Macronutrients

N – nitrogen (leaves, growth)

P – phosphorus (roots, flowers)

K – potassium (health, plant strength)

Micronutrients

Magnesium, calcium, iron, manganese, molybdenum, zinc…
Trace amounts are enough, but you can't do without them.

Good nutrition is one that contains everything in the exact ratio – which is why Hesi nutrients are so popular among growers.

🌿 Hesi nutrients: how they work in hydroponics

🔹 Hesi Hydro Growth

Phase: growth/vegetative period
It contains high amounts of nitrogen and microelements to help plants grow quickly, develop strong stems and roots.

🔹 Hesi Hydro Bloom

Stage: flower/fruit
Ideal for plants such as tomatoes, peppers or chillies. It has more phosphorus and potassium, which promote flowers and fruit formation.

🌟 Accessories that make a difference

These accessories often separate average hydroponics from perfect ones:

🔸 Hesi SuperVit

Concentrated vitamins and amino acids.
Thanks to it, plants respond faster to light, grow better and have a richer aroma (great for herbs).

🔸 Hesi Root Complex

Invaluable at launch.
It promotes root formation, helping seedlings, cuttings and weaker plants restore vitality.

🔸 Hesi PowerZyme

Enzymes that break down dead root parts and keep the tank clean.
This reduces the risk of mold, the roots absorb nutrients better and the water stays fresh longer.

💧 How to dose nutrients? (Practically and simply)

1) Young plants and seedlings

50% of the recommended dose of Hesi Growth

Add Root Complex regularly for the first 1-2 weeks.

SuperVit is enough once a week

2) Herbs and salads in growth

100% dosage of Hesi Growth

SuperVit 1–2 times a week

PowerZyme once a week for clean roots

3) Tomatoes, chili, peppers – flowering stage

Switching to Hesi Bloom

Dosage 100–120% depending on plant strength

SuperVit continue

PowerZyme regularly for a clean root zone

🌡️ Do I have to deal with pH and EC?

If you change the water regularly (10-14 days), this is usually not even necessary.
Hesi nutrients are designed to stabilize pH themselves.

For perfectionists:

pH: 5.8–6.2

EC: 1.2–1.8 for herbs, 2.0+ for fruits

But for beginners, it is usually enough to just follow the dosage.

📝 Summary

Hesi nutrients are among the simplest and most effective solutions for home hydroponics.
In practice, we have found it best to use:

Hesi Hydro Growth – for growth

Hesi Hydro Bloom – for flowers and fruits

SuperVit – for vitality and better growth

Root Complex – for roots and plant start-up

PowerZyme – for clean roots and healthy water

Just change the water regularly, stick to a simple dosage and the plants will grow like a race.
