More Grocery Store Hacks: Growing Exotic Rhizomes for Less

Dr. Russell Sharp explains how to use store-bought seeds, rhizomes and tubers—like spelt, mung beans, turmeric, ginger, galangal, sweet potatoes and more—as propagation material for hydroponic crops and microgreens.

He covers practical tips (avoid roasted seeds, look for buds, and watch for disease risks), nutrient considerations for rhizomes, and money-saving business ideas such as producing sweet potato slips.

The episode balances low-cost DIY propagation techniques with cautions about viruses, aflatoxins and when to prefer certified seed stock.
