Indoor Hydroponic Gardening Shows Promise for Cancer Patient Well-being

A new study reveals that indoor hydroponic gardening – growing plants without soil using nutrient-rich water – may significantly improve the mental health, dietary habits, and overall quality of life for individuals undergoing cancer treatment. The findings, stemming from a pilot study conducted by researchers at the Texas A&M University School of Public Health and the Houston Methodist Cancer Center, suggest a readily accessible and potentially powerful supportive intervention for cancer care.
The research, published in Frontiers in Public Health, builds on the well-established benefits of traditional gardening. “The health benefits of being outdoors are well documented, and cancer patients who garden have less pain, need fewer pain medications and are less likely to have a recurrence,” explained Taehyun Roh, a faculty member with the Department of Epidemiology and Biostatistics who spearheaded the study. “Since many patients don’t have access to a traditional garden or are physically unable to garden, we wanted to explore whether an easy-to-use indoor hydroponic system could offer similar benefits.”
Study Details and Participant Demographics
From October 2022 to September 2023, researchers worked with cancer patients at the Houston Methodist Cancer Center. Participants, with an average age of 57, were a diverse group: 47% were men, 53% were women, 59% identified as white, and 31% as Hispanic. The majority possessed at least some college education and private health insurance. Interestingly, despite over 90% of participants reporting access to a yard or garden space, most indicated they did not actively garden.
Each participant received an AeroGarden brand hydroponic kit, complete with a growing container, LED grow light, liquid plant food, and seed pods for heirloom salad greens. Over an eight-week period, they were responsible for planting, cultivating, and harvesting their own crops.
Significant Improvements in Mental and Physical Health
Researchers meticulously tracked participants’ mental well-being, psychological distress, quality of life, fruit and vegetable intake, and pain management levels at the beginning of the study, and again at four and eight weeks using validated survey instruments. The results revealed several statistically significant improvements.
Notably, mental well-being steadily increased throughout the eight weeks, accompanied by a substantial reduction in reported depression levels. Participants also experienced a better overall quality of life, with improvements in emotional and social functioning becoming apparent as early as week four. Furthermore, appetite loss decreased, and many participants reported an increase in their consumption of fruits and vegetables.
“The improvements observed may be explained by gardening’s ability to engage the senses, reduce stress through autonomic nervous system modulation and foster a sense of responsibility and control,” Roh stated.
Limitations and Future Research
While the findings are encouraging, Roh cautioned that the study’s pilot nature presents certain limitations. These include a relatively small sample size, a short study duration, and the absence of a control group. “Larger-scale studies are needed to confirm the findings,” he emphasized.
Despite these limitations, the research suggests that indoor hydroponic gardening holds “real potential as a supportive intervention in cancer care — and perhaps beyond,” Roh added. “We hope that these findings could extend to all people who lack access to conventional gardening or to nature, enabling them to increase their overall well-being.”
The study was supported by the Center for Health and Nature, a collaborative effort between Houston Methodist Hospital, Texan by Nature, and Texas A&M Health. Contributing researchers included graduate students Anisha Aggarwal, Nishat Tasnim Hasan, and Nusrat Fahmida, along with Charles Hall, Ellison Chair of International Floriculture and professor with the Texas A&M College of Agriculture and Life Sciences, and colleagues from Houston Methodist.
