Yes, the height of capillary activity is dependent on the soil medium used. For instance, with a popular potting soil (such as Miracle-Grow), the water will attain a practical height of 6” to 7”. Pots are referred to by their top circumference. In general, a “10” pot is the max that should be used with artesian systems. All pots available on our site will work fine with Miracle-Gro or similar.
By adding Coco Coir to the soil formula, you can get a great capillary activity and can use a taller pot.
