Mint vs Basil for Hydroponic Growing (2026)
Mint yields 30–60 g/plant per cycle in 28–35 days but requires a dedicated system due to aggressive root spread, while basil produces 25–40 g/cycle 7 days faster and coexists well with other herbs - making basil the more versatile system choice.

Mint and basil are both Easy-rated herbs with overlapping EC ranges (1.0–1.6 for basil, 1.6–2.0 for mint), but mint's aggressive rhizomatous root system is the deciding factor for system design. Mint must be isolated - it will physically block NFT channels or crowd DWC baskets - while basil integrates cleanly into mixed herb systems.
Side-by-Side Comparison
| Feature | Mint | Basil | |---------|------|-------| | Difficulty | Easy | Easy | | Days to First Harvest | 28–35 | 21–28 | | pH Range | 6.0–7.0 | 5.5–6.5 | | EC Range (mS/cm) | 1.6–2.0 | 1.0–1.6 | | Light (h/day) | 12–14 | 14–16 | | Water Temp (°C) | 15–22 | 18–24 | | Yield per Plant | 30–60 g | 25–40 g/cycle | | Key Flavour Profile | Cool, menthol | Sweet, clove-like |
Where Mint Wins
- Higher peak yield per plant (up to 60 g vs basil's 40 g) once established.
- Perennial growth habit means a single established plant produces multiple cuts without re-seeding.
- Lower minimum light requirement (12 h) suits compact, lower-wattage setups.
Where Basil Wins
- 7 days faster to first harvest (21 days vs 28 days minimum for mint).
- Mixes safely with other herbs in a shared NFT or DWC system - no root isolation needed.
- Needs lower EC (1.0–1.6) so it can share a reservoir with lettuce and other low-EC crops.
Growing Them Together
Not recommended in the same channel or reservoir. Mint's roots expand aggressively and will encroach on basil's root zone, reducing basil yield by blocking nutrient flow. If you want both, use separate net pot containers in a raft system with a physical divider, or run them in separate channels of a multi-channel NFT unit.
Which Should You Grow?
- Choose Mint if you want a perennial producer, can give it a dedicated channel or pot, and prefer the higher peak yield over 4–5 cuts.
- Choose Basil if you want the fastest cycle, need a herb that integrates into a mixed system, and prefer flexibility to switch varieties each cycle.
- Grow both if you have at least two separate reservoirs or a large raft system where you can physically segregate mint to one end.
