In a controlled room, every input is set and measured. Change the recipe, and the plant changes how much of each molecule it makes. Keep the recipe, and it makes them again.
01
A seed
The genetics stay the same. We never modify the plant.
02
Light
Intensity, spectrum and day length, set and measured.
03
Climate
Temperature and humidity, held to the protocol.
04
Nutrition
A nutrient recipe that steers how the plant makes its molecules.
05
A protocol
The recipe, validated analytically and repeated every week.
What you can specify
Three things, set with you.
01
Custom botanicals
Species and target compounds chosen with you. A protocol developed for your specification, under exclusivity.
02
Higher metabolite content
Light, climate and nutrition steer the plant toward the molecules you need.
03
Consistent quality
Same protocol, same environment. Every batch is measured against the specification before release.
MRP-1™
Every program makes the next one faster.
Protocols are developed with MRP-1™, our proprietary model of how a plant’s metabolism responds to light, climate and nutrition. Each cycle tests the most promising scenarios first. You receive its output: a validated protocol.
No pesticides. No soil. No genetic modification.

Inside MRP-1™
Measure. Model. Rank. Learn.
01
Measure
Every room logs light, climate and nutrition. Every batch is analysed for its metabolite profile by chromatography (HPLC, GC-MS).
02
Model
MRP-1™ links growing conditions to the molecules the plant makes, species by species.
03
Rank
Before we grow, it ranks growing scenarios by the expected amount of your target compound per square metre. The most promising are tested first.
04
Learn
Each new batch feeds the model, so every program starts closer to the target than the last.
Objective
More target compound per m²
Within your specification, batch after batch.
What you receive
A validated growing protocol
Not software: a recipe of light, climate and nutrition, proven analytically.
Ownership
MRP-1™ stays with Horssol
The protocol developed for your specification stays exclusive to you.
How we work
One site, from seed to analysed batch.
01
Traceability
One site, one protocol, one batch record, from seed lot to shipment.
02
Supply security
Harvests all year, planned with you, independent of season and weather.
03
Batch consistency
Each batch is measured against the agreed specification before release.
04
Grown without pesticides
A closed, clean environment removes the need for crop protection treatments.
05
Resource efficiency
Closed-loop irrigation and no arable land used.
06
Made in France
Grown and analysed in Lille, with a team trained in controlled environment agriculture.
Questions
Frequently asked questions.
How can the environment change what a plant produces?
Plants adjust how much of each molecule they make in response to light, climate and nutrition. In a controlled room every input is set and measured, so a recipe that steers a target compound can be repeated.
Which inputs are controlled?
Light, climate and nutrition. The seed, and therefore the genetics, stays the same.
What is MRP-1™?
MRP-1™ is Horssol's proprietary model of how a plant's metabolism responds to light, climate and nutrition. It ranks growing scenarios so that the most promising ones are tested first.
What does a client receive at the end of development?
A validated growing protocol (SOP) and reproducibility data, followed by regular supply against the agreed specification.
