[Support request] AirDome in Organic Soil? To Parent Forum May 30, 2023 at 12:11 pm #1215 outwestParticipant Tried the search and came up with noting. If you are in organic soil it might not be the best medium for the air domes. My medium has some aeration in it, but not much, and based on the descriptions and guidelines, it seems the air domes are not ideal in this medium. Can someone confirm this? Thanks!
