A passive, gravity-fed sub-irrigation system where pots sit on trays equipped with AQUAvalve float valves that automatically deliver water/nutrient solution from a reservoir only when the growing medium dries down sufficiently.
The AutoPot XL 5-gallon pots were set up in the 4x8 indoor tent. The key lesson of the episode was that AutoPot's guidelines recommend a free-draining, aerated substrate and at least a 1-inch base layer of inert drainage material. Running 100% coco without aeration amendment caused issues and required a full re-transplant.
