I've started 16 hydroponic cups of dandelion, and I look forwards to harvesting seeds and leaves in 30 days. I hope and hope and hope that dandelion roots are not susceptible to root rot. Tomorrow, I will start 6 plants in a trough and we'll see how well those do. Dandelion leaves are bitter. They do well when paired with a sharp vinaigrette further sharpened with a Dijon mustard. I've placed the hydroponics kits in a sunny location of my apartment out of the rain.
