9 common mistakes when growing at home + solutions
What are the most common mistakes made when growing at home? Many beginners make the same mistakes, causing plants to grow less well or even die. In this blog, we explain which mistakes you should avoid and how to achieve better results immediately.
💧 1. Overwatering
One of the most common mistakes is overwatering. Plants need oxygen at their roots, and overly wet soil hinders this process.
- Roots get too little oxygen
- Growth slows down or stops
- Risk of root rot increases
👉 Let the top layer of the soil dry out slightly before watering again.
🔦 2. Incorrect use of grow lights
Light is the most important energy source for plants. Too little light leads to weak growth, while too much light can cause damage.
- Too low wattage per m²
- Incorrect distance to the plant
- Incorrect light schedule
👉 Use approximately 200–300W LED per m² and maintain a distance of 30–60 cm from the plants.

🌡 3. Poor climate (temperature and humidity)
A stable climate is essential for healthy growth. Fluctuations cause stress and growth problems.
- Too hot → dehydration and stress
- Too cold → slow growth
- Too humid → mold formation
- Too dry → poor absorption
👉 Ideal is 20–28°C and 40–70% humidity depending on the growth phase.

💨 4. Insufficient ventilation
Many beginners underestimate the importance of ventilation. Without good air circulation, an unhealthy climate develops.
- Build-up of heat and moisture
- Poor oxygen supply
- Increased risk of mold
👉 Ensure good extraction and air circulation with fans.
⏱ 5. No consistent light schedule
Plants need structure. Irregular light causes stress and can disrupt growth.
- Growth phase: 18 hours light / 6 hours dark
- Flowering phase: 12 hours light / 12 hours dark
👉 Always use a timer for a stable light schedule.
📏 6. Choosing the wrong size grow tent
A grow tent that is too large or too small can make it difficult to control the climate properly.
- 60x60 cm → beginners
- 80x80 / 100x100 cm → most chosen
- 120x120 cm → advanced
👉 Choose a size that suits your space and experience.
⚡ 7. No control over energy consumption
Unnecessary energy consumption often results from inefficient equipment or incorrect settings.
- Use LED lighting
- Set timers correctly
- Optimize ventilation
👉 With the right setup, you can easily save on costs.
🌱 8. No daily check
Many problems arise because growers do not check regularly.
- Not measuring temperature and humidity
- Noticing problems too late
- Not making adjustments
👉 Check your setup daily and adjust where necessary.
❌ 9. Unrealistic expectations
Home growing is a process. Don't expect perfect results immediately.
- Start small and learn step by step
- Optimize your setup per grow
- Focus on stability
👉 Experience is the key to success.
