Do you have any problems with water and soil draining and getting on the leaves? I wondered if soil-borne diseases would be a problem with this growing method. Maybe the use of sterile potting soil would prevent diseases?
Maybe. I’m using Sta-Green Moisture Max (or Miracle Gro Moisture Control) soil in the buckets, and in the raised bed for that matter. I’m also spraying with some 3 in 1 stuff from Lowes to guard against insects and disease.
