Indoor cultivation allows for the control of many parameters, but humidity remains a major challenge. If it is too high, it promotes mold, root rot, and the development of pathogenic fungi. If it is too low, it slows down plant growth and can cause water stress.

💡 Many growers underestimate the impact of humidity and do not take the time to analyze their environment before getting started. However, poor humidity management can ruin a crop in the middle of the cycle, and there... hello financial losses! 😵

In this article, we will explore ALL the angles of the problem and provide you with concrete solutions to maintain a healthy and productive culture. 🚀

🔍 Understanding the Impact of Humidity on Plants

The ideal relative humidity for indoor cultivation varies according to the growth stages:

✔ Vegetative growth : 50-70 %
✔ Blooming : 40-50 % (to prevent flower mold)
✔ End of flowering : 35-45 %

If these values are not respected, you risk having:

🚨 A development that is too slow (if the humidity is too low).
🚨 Mushrooms and mold (if the humidity is too high).
🚨 Poor nutrient absorption due to water stress.

In short, a poorly managed climate can cost you several weeks of work! 😫

🏠 The Influence of Location on Humidity

Before even setting up your grow tent, ask yourself this question: in what type of room will you be growing?

🔹 The cellar: Very humid, with stagnant air promoting mold. A powerful dehumidifier is essential.
🔹 The garage : Humidity can vary greatly depending on the seasons. Insulation and humidity control are necessary.
🔹 The attic: Often very dry in summer and very humid in winter. A humidifier or a dehumidifier may be necessary depending on the season.
🔹 The laundry room : To be avoided, as it is generally too humid due to the washing machines.
🔹 A room or an office : The environment is more stable there, but it is important to ventilate well to avoid moisture accumulation.

👉 Before setting up your growing space, take the time to measure the ambient humidity with a hygrometer! 📊

🛠️ Essential Equipment for Regulating Humidity

🎯 To keep a culture under control, here are the essential equipment:

1️⃣ The Hygrometer: The Basic Tool

First of all, invest in a digital hygrometer to monitor humidity in real time. A model with data history and alerts is even better to avoid unpleasant surprises.

2️⃣ The Dehumidifier: Against Excess Humidity

If you are growing in a basement or garage, a good dehumidifier is essential. It will help to stabilize humidity below 60% and prevent mold.

✔ Small space (less than 5m²) : A compact dehumidifier is sufficient.
✔ Large space (more than 5m²) : Choose a more powerful model with automatic drainage.

3️⃣ The Humidifier: For Too Dry Spaces

If the air is too dry (less than 40% humidity), especially in winter, a humidifier is necessary. Opt for a model with automatic adjustment to avoid over-saturating the air.

4️⃣ Fans: To Avoid Stagnation Zones

Even with good humidity control, without air circulation, mold can develop. Install an oscillating fan to homogenize the air in your grow tent.

5️⃣ The Air Extractor: A Must-Have

A good extractor with a charcoal filter allows for air renewal and prevents excess humidity. Without it, stale air stagnates and encourages the proliferation of mold.

🏺 The Pots: A Crucial Choice Against Mold

As mentioned earlier, plastic pots promote moisture accumulation. A poorly thought-out choice can ruin your crop in the middle of the cycle.

✅ Geotextile pots and Air-Pot are a much better option!

✔ They promote root aeration.
✔ They allow for more efficient water drainage.
✔ They reduce the risks of mold and rot.

Avoid skimping on pots! When you add up the expenses for electricity, water, equipment, and genetics, losing a crop for a few saved euros really hurts the wallet. 😅

🛡️ Prevention: Protect Your Crop Against Fungi

Even with good humidity management, it is important to use preventive treatments to avoid fungal infections.

✔ Botryprot : Protects your plants against Botrytis (gray mold).
✔ Oidioprot : Prevents the appearance of powdery mildew on the leaves.
✔ Mildiuprot : Fights against downy mildew, a fungus that can destroy a plant in a few days.

These products are to be applied as a preventive spray to avoid having to manage an infection once it has taken hold.

🎯 Conclusion: Good Humidity Management, Guaranteed Success!

Growing indoors requires particular attention to humidity. Failing to manage it properly can lead to significant financial losses and a huge waste of energy.

🔹 Before you start, analyze your growing environment!
🔹 Use appropriate equipment: extractors, fans, hygrometers, etc.
🔹 Choose suitable pots to avoid water stagnation.
🔹 Use preventive treatments against fungi.

💡 A good grower leaves nothing to chance! And when we see the electricity and investment bills, it's better not to miss the mark. 😆
