Hydroponic Peanuts: Can We Grow Them Without Soil?

Dr. Russell Sharp explores experimental research on growing peanuts hydroponically, summarizing NASA studies and university trials using deep water culture (DWC) and nutrient film technique (NFT). He explains the peanut life cycle—flowering, peg (gynophore) formation, and pod development—and why pegging into a moist zone or specially designed trays is critical.

The episode covers nutrient needs (especially calcium), aeration, potential water savings compared with soil, and the challenges of commercial production. It highlights peanut hydroponics' experimental status, possible benefits for water-limited farming, and opportunities for custom fertilizer development.
