Bristol vertical and indoor farming innovator LettUs Grow has secured £2.35m in seed funding to scale-up delivery of its game-changing technology to farmers across the UK.
LettUs Grow’s award-winning indoor farming system for greenhouses and vertical farms aims to address global food security and sustainability concerns. 
These indoor farms need no fertile land to operate, use zero pesticides and provide a consistent, predictable and climate-resilient food supply all year round.
LettUs Grow’s offering is centred on two core products – a novel aeroponic system and an integrated farm management software called Ostara.
LettUs Grow has shown growth rate increases of more than 70% across a range of crops, compared to current vertical farming methods such as hydroponics.
Ostara automates and controls the whole indoor farm, while collecting data on plants, overseeing inputs to crop growth and allowing farmers to trace crops from seed to sale, making operations more efficient.
LettUs Grow was founded to mitigate the risks posed to agriculture by the climate crisis and to lessen the environmental impacts of growing fresh produce.
Having built one of the world’s most advanced indoor aeroponic growing facilities last year and with a growing pipeline of sales with key clients, LettUs Grow says it is well positioned to become a global leader in the indoor farming technology supply chain.
The funding round, which was led by Oxfordshire-based early-stage tech investor Longwall Venture Partners, will allow LettUs Grow to build its second state-of-the-art aeroponic research centre, scale its existing technology, deliver on its growing sales pipeline and accelerate new product lines.
LettUs Grow co-founder and managing director Charlie Guy, pictured, said: “This investment gives us a platform to really accelerate in 2020 and scale-up the delivery of our game-changing technology to farmers across the country.
“We’re seeing rising demand from around the world for new technologies to help farmers grow crops in ways that mitigate against the effects of climate change and ever-increasing extreme weather events.”
Longwall Ventures investment director Rebecca Todd added: “Food security is an emerging major international challenge, especially in this era of unpredictable climate that we are now entering. We at Longwall are excited to be backing LettUs Grow in the development of game-changing technology that has the potential to make a real difference by making food growing more efficient, predictable, controllable and local.”
The round also included follow-on investment from the University of Bristol Enterprise Fund (managed by Parkwalk), Bethnal Green Ventures and ClearlySo, with legal representation from Bristol-headquartered law firm VWV.
