The flowering phase is one of the most important stages in your plant’s life. Whether you’re growing cannabis, tomatoes, or ornamental plants, proper care during this time determines the yield, quality, and health of your plants. To help you get the most out of this phase, we’ve compiled the most important dos and don’ts for you.

Dos in the flowering phase
1. Regular care & inspection
During flowering, you should check your plants daily. Pay attention to:
- Nutrient supply: Special flowering fertilizers promote flower formation.
- Pests and diseases: Spider mites or mildew can now quickly cause damage.
2. Increase light intensity
More light = more flowers!
- Cannabis & Co.: Maintain 12 hours of light, 12 hours of darkness.
- Ornamental plants: Make sure the light is bright enough, but not too bright.
3. Keep an eye on temperature and humidity
- Ideal temperature: 20–26°C (slightly cooler at night).
- Humidity: 40–50% – too high humidity promotes mold!
- Tip: A hygrometer helps you keep an eye on the values.
Don’ts during the flowering phase
1. Avoid over-fertilization
Too many nutrients can ruin the flower quality!
- Symptoms: Burnt leaf tips, slow growth.
- Solution: Follow the dosage recommendations or reduce slightly.
2. Don’t overwater
Waterlogging is the enemy of every plant!
- Danger: root rot, lack of oxygen.
- Tip: Only water when the top layer of soil is dry.
3. No extreme temperature fluctuations
Sudden heat or cold stresses the plant!
- Problem: Flowers can fall off or wither.
- Solution: Create constant conditions (e.g. with ventilation or heating mat).
How to get the most out of it
The flowering phase determines your harvest success! With the right do’s (light, nutrients, climate) and the most important don’ts (overfertilization, waterlogging, stress), you can ensure healthy, strong blooms. Monitor your plants closely and adjust your care as needed – then nothing will stand in the way of a successful harvest!
