Letplant

LetPlant addresses the environmental impact of poor indoor houseplant care, which contributes to high waste rates and undermines urban sustainability. Research shows that 70% of houseplants die within the first year, leading to unnecessary carbon waste from repeated production, packaging, and shipping. Additionally, most homes lack indoor air quality awareness despite the WHO estimating 9 out of 10 people breathe polluted indoor air. LetPlant's Al and sensor-driven system (LetPlant SDESA) reduces waste by improving houseplant survival and uses real-time air quality data to inform healthier indoor living. By empowering users to care for houseplants more effectively, we reduce carbon emissions, support biodiversity, and improve indoor environments at scale. With over 27 million households in the UK alone owning houseplants and over 1 billion indoor plant sales globally, the potential climate benefit of increasing plant survival and health is substantial and scalable.
