Most of the container potato setups I see use a lot of sand and straw which I thought would help with the fungal growth, though they’re usually set up in something like a large trash can with an air layer of insulation around since it hold heat less than rocks but the white block idea with sunken drip line sounds intriguing. We get a lot of clay in my area, but it’s also pretty rainy most of summer so I would probably need some sort of sensor in the soil to figure out when it’s dried enough for more watering. Thanks for the response!
How dare they mess with Sh, It Just Works.
