Arugula vs Mizuna for Hydroponic Growing (2026)
Mizuna matures 3–7 days faster than arugula (18–28 days vs 18–25 days at the low end) and produces 35–65 g of feathery mild leaves, while arugula's peppery bite commands higher restaurant value at 30–50 g per tray.
Last updated
Arugula and mizuna are both fast-growing salad greens that thrive in cool, low-EC hydroponic systems. They share similar cycle times (18–28 days for both) and light requirements (10–12 h), but differ in flavour, yield, and pH tolerance. Mizuna is milder and yields slightly more (35–65 g vs 30–50 g), while arugula's distinct peppery flavour positions it as a premium ingredient.
Side-by-Side Comparison
| Feature | Arugula | Mizuna | |---------|---------|--------| | Difficulty | Easy | Easy | | Days to First Harvest | 18–25 | 18–28 | | pH Range | 6.0–7.0 | 5.5–6.8 | | EC Range (mS/cm) | 0.8–1.4 | 0.8–1.6 | | Light (h/day) | 10–12 | 10–12 | | Water Temp (°C) | 15–21 | 15–22 | | Yield per Plant | 30–50 g/tray | 35–65 g/baby | | Key Flavour Profile | Peppery, nutty | Feathery, mild, slightly mustard |
Where Arugula Wins
- More distinctive flavour profile commands restaurant premium pricing.
- Slightly cooler optimal water temperature (15–21°C) suits cold-basement grow rooms.
- Holds peppery flavour profile even at older leaf stage.
Where Mizuna Wins
- Higher yield ceiling: up to 65 g vs arugula's 50 g per equivalent tray area.
- Wider EC range (up to 1.6 vs arugula's 1.4) gives more nutrient flexibility.
- Milder flavour has broader consumer appeal for family cooking and mixed salad blends.
Growing Them Together
These two are near-perfect system-mates: both run at EC 0.8–1.4, similar pH (overlap at 6.0–6.8), and identical light schedules (10–12 h). The main consideration is water temperature - arugula's upper limit (21°C) is 1°C lower than mizuna's (22°C). Keep reservoir at 18–20°C and both thrive simultaneously in the same NFT channel.
Which Should You Grow?
- Choose Arugula if you target restaurant or premium retail customers who pay a flavour premium for peppery greens.
- Choose Mizuna if you want a higher-yield mild green suitable for mixed salad blends and broader market appeal.
- Grow both if you want a mixed salad product - arugula and mizuna together create a balanced peppery-mild mix that is popular in mesclun blends.
