Key Takeaways
- Ceres Greenhouse Solutions (Boulder, Colorado) and LettUs Grow (Bristol, UK) have announced a strategic partnership to deliver turnkey greenhouse solutions combining energy-efficient infrastructure with Advanced Aeroponics irrigation technology.
- The collaboration is designed to expand LettUs Grow's North American footprint while giving Ceres Greenhouse access to proven aeroponic technology validated through partnerships with Wageningen University and commercial installations across Europe.
- Spinach is the initial focus crop, with LettUs Grow's aeroponic trials demonstrating over 50% higher yields than hydroponics in the same growth cycle and a 96% saleable yield rate.
- LettUs Grow's Advanced Aeroponics system uses patented ultrasonic misting to deliver water and nutrients directly to plant roots suspended in air, providing oxygen levels that hydroponic systems cannot match.
- The partnership targets a broad grower spectrum, from large commercial operators to community-scale installations, with modular systems expandable to lettuce, herbs, microgreens, and specialty crops.
Ceres Greenhouse Solutions and LettUs Grow Form Strategic Partnership
Ceres Greenhouse Solutions, the Boulder, Colorado-based greenhouse design firm founded in 2011, and LettUs Grow, the Bristol-based aeroponic technology company, have announced a strategic collaboration to deliver integrated growing systems to commercial and community-scale growers across North America and globally. The partnership combines Ceres's expertise in energy-efficient greenhouse design, climate control, and renewable energy integration with LettUs Grow's Advanced Aeroponics technology, which the company has been developing and refining for over a decade.
For LettUs Grow, the collaboration addresses a specific geographic gap: while the company has established partnerships with European greenhouse constructors including CambridgeHOK, KG Systems, HT Verboom, and HAWE, it had been seeking a partner to extend its reach into North American markets. Ceres, with 15 years of project delivery experience across North America and internationally, fills that role.
Spinach Results Make the Case for Aeroponics
Spinach has historically been a difficult crop in controlled environment agriculture. Hydroponic systems present persistent challenges including poor germination, slow early growth, susceptibility to Pythium and root rot, and premature bolting — all attributed to insufficient oxygen at the root zone. LettUs Grow's Advanced Aeroponics system addresses this directly by suspending plant roots in air and delivering nutrients via ultrasonic mist, producing oxygen levels that conventional hydroponic systems cannot replicate.
Commercial trials conducted by LettUs Grow reported yields more than 50% higher than hydroponic comparators within the same growth cycle, a saleable yield rate of 96%, consistently healthy root systems despite the presence of standard fungal pathogens, and superior leaf quality with dark coloration and minimal nutrient deficiencies.
What the Ceres Greenhouse and LettUs Grow Partnership Delivers to Growers
The partnership is structured to offer complete turnkey systems: greenhouse structure, climate control, heating, renewable energy integration, and aeroponic irrigation delivered as a coordinated package. Both companies emphasise modularity — growers can start with spinach and expand to lettuce, herbs, microgreens, propagation, or specialty crops as operations scale. Ceres brings knowledge of North American climate conditions and regulatory environments; LettUs Grow contributes insights drawn from European deployments and a global partner network.
The two companies frame the collaboration as part of a broader shift in controlled environment agriculture toward integrated systems over isolated technologies, with a stated focus on what demonstrably works for commercial growers rather than technology-led market narratives.
