About this episode
In this episode Dr. Russell Sharp explores the practical science of growing crops on Mars — water sources and site choices, lighting and power options, and why indoor, LED‑lit hydroponics (NFT, aeroponics) is most likely.
He examines Martian regolith as a potential grow medium (nutrient content, perchlorates and removal methods), atmospheric challenges, closed‑loop recycling, automation and 3D‑printed systems.
The episode closes with priority crop choices (potatoes, leafy greens, microgreens, herbs), psychological needs for colonists, and the importance of robust, fail‑safe farm design for long‑term habitation.
