A small pilot study in Houston suggests that tending countertop hydroponic gardens could bolster mental health and overall quality of life for people living with cancer. Thirty-six adults, average age 57, undergoing outpatient infusion therapy were given AeroGarden kits to grow vegetables at home over eight weeks.
Researchers described the approach as aligning with social prescribing, a non-clinical means of supporting wellbeing through everyday activities. The aim was to explore whether indoor gardening could provide psychological relief alongside medical treatment.
Hydroponics offers an indoor alternative to traditional outdoor gardening, requiring no soil and enabling year‑round cultivation with artificial light and liquid nutrients. This method avoids soil-borne pathogens, weeds and herbicides, while making gardening accessible in dense urban settings or during taxing medical regimes.
The participant group comprised adults with various cancers who had completed at least one chemotherapy cycle. The study used a case-crossover design, meaning each participant served as their own baseline for comparison over time rather than using a separate control group.
All participants received an AeroGarden countertop system to cultivate heirloom salad greens. The kit included a growing container, an automated LED grow light, liquid plant food and twelve seed pods, designed to be highly accessible even for first-time gardeners.
Over eight weeks, participants managed the kits at home—planting seeds, monitoring water levels and eventually harvesting the greens. They were provided with instructional materials and manufacturer manuals to help optimise growth and troubleshoot common issues.
Researchers surveyed participants at the start, at four weeks and at eight weeks using standard questionnaires to measure mental wellbeing, psychological distress and overall quality of life. The assessments covered physical functioning, emotional wellbeing, pain levels and fruit-and-vegetable consumption.
Across the eight weeks, participants reported steady improvements in mental health. Mental wellbeing scores rose, while self-reported symptoms of depression declined from baseline to the study’s end.
Quality of life also improved, with gains in emotional and social functioning and a diminished sense of appetite-related difficulties noted by participants as the study progressed.
Dietary changes emerged as well, with participants consuming more fruits and dark green leafy vegetables by the conclusion of the study.
Not all measures shifted significantly. Pain management scores trended downward but did not reach statistical significance, and changes in anxiety and stress levels were also not statistically significant during the eight weeks.
The researchers propose several psychological mechanisms for the observed benefits: nurturing plants can foster a sense of responsibility and achievement, which may be especially valuable for patients experiencing a loss of autonomy during treatment. The multisensory engagement of tending plants is also thought to support cognitive restoration and natural stress relief.
Limitations include the single-arm design and potential self-selection bias, since all participants received the gardening kits. The eight-week duration and reliance on self-reported kit usage without independent verification further limit the findings. The authors call for larger, longer studies with objective tracking to determine whether benefits endure beyond the pilot phase.
