How to Set Up an Indoor Herb Garden (Year-Round Fresh Herbs)
Basil, cilantro, mint, rosemary, and more — harvest fresh herbs from your kitchen any time of year
Soil & Hydro OptionsKitchen Friendly10+ Herb VarietiesBeginner Guide
An indoor herb garden is one of the most practical and rewarding projects for any home grower. Fresh herbs from your kitchen window or a small grow light setup produce far better flavor than store-bought, and many herbs grow so quickly that you can harvest every 1–2 weeks indefinitely. Here is how to set up a productive, space-efficient indoor herb garden.
Best Herbs for Indoor Growing
| Herb | Light Needs | Days to Harvest | Ideal System |
|---|
| Basil | High (16 hrs) | 25–30 days | DWC, NFT, soil |
| Mint | Medium (12–14 hrs) | 30–40 days | Any (invasive — isolate) |
| Cilantro | Medium (12–14 hrs) | 25–35 days | Kratky, soil |
| Parsley | Medium (12–14 hrs) | 45–60 days | Soil, coco |
| Chives | Low (10–12 hrs) | 30–40 days | Soil, any system |
| Rosemary | High (16 hrs) | 90+ days to establish | Well-drained soil |
| Thyme | Medium-High (14–16 hrs) | 70–90 days | Well-drained soil |
| Oregano | High (16 hrs) | 70–90 days | Soil, coco |
Option 1: Soil-Based Setup
The simplest approach. Use 4–6" pots with quality potting mix, a drip tray, and a T5 or LED panel grow light. This method is forgiving and familiar — treat it like house plants but with more light.
- Pots: 4" for small herbs (basil, cilantro), 6–8" for rosemary and mint
- Medium: Fox Farm Happy Frog or any quality potting mix with good drainage
- Light: 4-bulb T5 fluorescent or 100–200W full spectrum LED, 12–16 hrs/day
- Water: when top inch of soil is dry; water thoroughly, allow to drain
- Nutrients: light feeding every 2 weeks with CalMag and dilute vegetative nutrients
Option 2: Hydroponic (Fastest Growth)
Hydroponic herbs grow 30–50% faster than soil-grown. A simple 6-site DWC system or Kratky jars on a shelf with a grow light produces abundant fresh herbs with minimal maintenance. Key settings for herbs:
- pH: 5.5–6.5 (same as vegetables — slightly acidic)
- EC: 0.8–1.6 depending on herb (soft herbs like basil prefer lower EC)
- Temperature: 65–75°F water temperature
- Light: 12–16 hours full-spectrum at 200–400 PPFD
💡 Tip: Start from Seed, Not Store Transplants Grocery store herbs are grown in nutrient-dense conditions and often have multiple plants per pot. They transplant poorly. Start from seed in rockwool or jiffy pellets for hydroponics, or direct-sow in your soil pots.

What is the best grow light for an indoor herb garden?
For a countertop herb garden or small 2×2 shelf, a 45–100W full-spectrum LED panel works well. T5 fluorescents (2-bulb or 4-bulb) are an economical option and produce excellent herb quality. Aim for 200–400 PPFD at plant canopy. AC Infinity and compact grow light both make compact panels perfect for herb shelves.
Can I grow herbs under regular LED house lights?
Standard household LED bulbs do not produce enough intensity or the right spectrum for productive herb growing. You need a grow-specific LED or high-output T5 fluorescent. Plants under household lighting will survive but grow slowly and become leggy (stretching toward light). A dedicated grow light makes a noticeable difference.
How often should I harvest herbs to keep them producing?
Most herbs — especially basil, mint, and cilantro — produce more prolifically the more you harvest. Pinch or cut stems just above a leaf node. Never remove more than 1/3 of the plant at once. For basil, regularly pinch off flower buds to extend the vegetative productive period — once it bolts (flowers), it stops leaf production.
What herbs grow best in hydroponics for beginners?
Basil and lettuce are the easiest hydroponic herbs for beginners — fast growth, minimal nutrient needs, and very forgiving of minor pH/EC swings. Mint grows vigorously in almost any hydroponic system. Cilantro grows fast but bolts quickly — sow new seeds every 3 weeks for continuous supply. Rosemary and thyme can be grown hydroponically but are slow to establish.
