Choosing the right crop to grow in a greenhouse will determine the final profitability of your hydroponic business, short term and long term. The most profitable crops to sell (we have in this list excluded medicinal cannabis here), is often related to short growing cycle and the local market demand. Below, we have listed some of the most profitable plants to grow hydroponically and the reason why they belong to this list.

Please note that the crops in this list are not ranked based on their profitability.

• Reason: Herbs have a high market demand, and their short growth cycles make them suitable for hydroponics. They also require relatively small spaces, allowing for efficient use of indoor farming (and especially for vertical farming systems). Fresh, locally grown, and high quality herbs are sought after by restaurants, farmers’ markets, and consumers, contributing to their profitability.

• Reason: Leafy greens are popular choices due to their quick growth, consistent demand, and suitability for hydroponic systems.They can grow really fast in nutrient-rich indoor environments and are well-suited for any kind of indoor farming (mid-tech greenhouse, high-tech greenhouse and high-tech vertical farming). With a continuous harvest cycle, growers can maintain a steady income stream.

• Reason: Tomatoes are consumed throughout the year in large quantities (In the European Union, the average person consumes about 14 to 15.6 kg of fresh tomatoes each year) and hydroponic cultivation allows for precise control over their growing conditions. This control results in higher yields and better-quality produce than field grown tomatoes. Also, if tomatoes can be grown locally, they don’t need to be imported from other countries.

  Hydroponically grown tomatoes also tend to develop faster, and as the tomato plants are grown indoors, they have a longer growing period allowing for more fruits harvests, and therefore increasing the profitability.

• Reason: Similar to tomatoes, bell peppers are highly sought after in the market and benefit from being grown in a controlled hydroponic environment.

• Reason: When done properly, hydroponic strawberry cultivation offers advantages such as reduced disease risk, better fruit quality, and extended growing seasons. The market demand for fresh, clean, good tasting and locally grown strawberries, especially in areas with shorter growing seasons, contributes to their profitability.
