How long herbs take to grow depends on the growing method and the type of herb. In general, herbs grow faster in hydroponic systems than in soil pots because water, nutrients, and oxygen are delivered more efficiently to the roots.
Below is a general comparison, ordered from fastest to slowest, based on typical indoor conditions.
Fast-growing herbs (quick harvest)
Mint
- Hydroponics: ~2โ3 weeks
- Pots (soil): ~3โ4 weeks
Mint grows very quickly and regrows fast after cutting.
Basil
- Hydroponics: ~2โ3 weeks
- Pots (soil): ~3โ5 weeks
Basil responds especially well to hydroponics and frequent harvesting.
Chives
- Hydroponics: ~2โ3 weeks
- Pots (soil): ~3โ4 weeks
Chives grow steadily and tolerate indoor conditions well.
Medium-speed herbs
Parsley
- Hydroponics: ~3โ4 weeks
- Pots (soil): ~4โ6 weeks
Parsley starts slowly but then produces leaves continuously.
Cilantro
- Hydroponics: ~3โ4 weeks
- Pots (soil): ~4โ5 weeks
Cilantro grows quickly at first but has a short life cycle.
Slow-growing herbs
Oregano
- Hydroponics: ~4โ6 weeks
- Pots (soil): ~5โ7 weeks
Oregano grows slowly but becomes more productive over time.
Thyme
- Hydroponics: ~4โ6 weeks
- Pots (soil): ~6โ8 weeks
Thyme grows slowly and needs patience indoors.
Rosemary
- Hydroponics: slow and challenging
- Pots (soil): ~6โ10+ weeks
Rosemary is one of the slowest indoor herbs and takes time to establish.
Why hydroponics is usually faster
In hydroponic systems, herbs grow faster because:
- Roots receive constant access to water and nutrients
- Oxygen levels around roots are higher
- Plants spend less energy searching for resources
In pots, growth is still reliable but usually slower due to soil resistance and nutrient variability.
