Profitability indoors is not only about plant value per kg, it’s about yield per space, speed to harvest, and frequency of harvests — especially compared to supermarket prices in the EU. The most profitable herbs and greens indoors tend to be those that are used frequently, grow quickly, and can be harvested repeatedly.
Here are the plants that, in most EU markets, tend to offer the best value for indoor growers when you compare:
- what you’d pay per unit in a grocery store vs
- what you can harvest at home with minimal inputs (seeds + light + water).
Top Indoor Plants by Profitability
1. Basil
- Why it’s profitable: Fast growth, frequent harvests, and high supermarket price-per-gram in Europe, especially fresh organic basil.
- Indoor advantage: Grows well hydroponically or in pots with consistent light, and you can harvest continuously.
- Typical use case: Daily cooking herb — so yields add up fast.
2. Microgreens (e.g., sunflower, radish, pea shoots)
- Why it’s profitable: Extreme yield per tray and short harvest cycle (often 7–14 days).
- Indoor advantage: Very quick turnover means many harvests per season, maximizing output per square meter.
- Typical use case: Gourmet salads and garnishes command higher prices in EU supermarkets/restaurants.
3. Leafy greens (lettuce, salad mixes, spinach)
- Why it’s profitable: Moderate to high supermarket prices and continuous harvest capability.
- Indoor advantage: Quick regrowth and multiple cuttings per planting make them efficient producers.
4. Parsley & Mint
- Why it’s profitable: Longer harvest life; a small plant continues producing for weeks.
- Indoor advantage: Very forgiving and yields a lot of usable herb matter over time.
What Makes These Plants Profitable
Fast turnaround + frequent harvests
Microgreens are especially noteworthy because they mature so quickly that you can grow several cycles in the time it takes lettuce or basil to reach full size. This spreads your input costs (light, water, seeds) over many harvests, increasing effective “profit per hour.”
High supermarket price per gram
Fresh basil and microgreens are often priced at a premium in EU stores (especially organic), meaning that even small quantities saved by growing at home represent real savings.
Low space requirements
Herbs and salad greens fit well into smart gardens and compact hydroponics, which makes them efficient for indoor setups where space is limited.
Continuous harvest potential
Plants that regrow after cutting (like basil, parsley, lettuce outer leaves) give more usable produce per plant without replanting — driving higher yield from the same roots.

Profitability Context (EU Grocery Prices)
While exact prices vary by country and season, in many EU markets:
- Packaged fresh basil (50–100g): €2.50–€4.50+
- Microgreens (30–50g tray): €3–€8+
- Bagged salad mixes (100–200g): €1.50–€3
- Parsley/Mint bunches: ~€1.20–€2.50
Indoor home production, especially with hydroponics or smart gardens, often pays for its running costs quickly because:
- You save on repeated supermarket purchases.
- You reduce waste (home harvest is fresh each time).
- You get multiple harvests per planting.
Even with electricity and seeds factored in, the “yield value per area per time” often beats what you’d pay for the same freshness and quality in stores, especially in Northern/EU climates with short outdoor seasons.
Summary
Most profitable indoor plants (EU context):
- Basil — frequent use + high price
- Microgreens — fastest cycles
- Leafy greens — continuous harvest
- Parsley & Mint — long productive life
These work well in smart garden systems or hydroponics, and they deliver noticeable cost savings compared to regular supermarket prices in the EU.
