Hydroponic greenhouse profitability: the factors to review

Updated on July 18, 2026

A hydroponic greenhouse is an investment project: it deserves a serious study before any decision. Rather than relying on a single criterion, several technical and commercial factors need reviewing. Here they are, and where to find the detailed estimates.

The three questions to ask

Three simple questions help frame a project: what can the greenhouse produce, what must be planned to run it, and who will buy the production?

  • Production: what volume to aim for, given the surface and crop?
  • Operation: which items to plan for (agronomic follow-up, electricity, water)?
  • Outlets: who to sell your production to, and how?

A technical benchmark: the 200 m² greenhouse

Take our best-documented model. As an indication, a 200 m² greenhouse holds 1,652 basil plants, for indicative production of about 2,900 kg per year. This benchmark is not a guaranteed result. Detailed estimates are in the brochure of the 200 m² greenhouse.

Scaling up: the 500 m² greenhouse

The 500 m² greenhouse holds 4,130 plants, for indicative production of about 7,250 kg per year. Larger models, such as the 1000 m² greenhouse, and custom projects are the subject of a personalized study.

The investment support application

Agricultural investment support schemes may be available depending on project eligibility. Our team can assist with the preparation of the application. We cover this topic in our article on APIA.

Outlets: a question to plan for

Good yields are not enough: you also need to know who will buy. We support you with commercial outlets for your production; the purchase conditions are set out in the brochure and in your quote.

What influences your results

Two identical greenhouses can give different results. Crop management (balancing the solution, pruning, maintaining the NFT system) makes yields vary; that is why we include training and agronomic follow-up. Production consistency, control of electricity use and the health of the circuit also play a part. To understand the technique, read the NFT system explained.

Frequently asked questions

How can I sell my production?

We support you with commercial outlets. The purchase conditions are set out in the brochure and in your quote.

Where can I find profitability estimates?

In each model's brochure, available for download. For your project, a personalized study takes your land and goals into account.

Which operating items should I plan for?

Mainly agronomic follow-up, electricity and water. The solar power supply of our recent installations aims to control electricity use.

What production can a basil greenhouse reach?

As an indication, about 2,900 kg/year for 200 m² and 7,250 kg/year for 500 m². These figures are not guaranteed.

Is investment support possible?

Agricultural investment support schemes may be available depending on project eligibility. Our team can assist with the preparation of the application.

Are the results guaranteed?

No. Results depend on the land, the water and crop management, hence the importance of follow-up.
