Whats the best way to automate watering for a soil grow in 7g smarties on ebb tables?

About the "BluMat" idea I commented on your other question, the flooding idea may work but you really are complicating it. When you flood while keeping a space under the pot, especially with fabric pots, you're more susceptible to mold and root damage! to automate your irrigation and grow in general a drip irrigation with a timer and pump would be best for you (considering you're growing in soilless medium) in my opinion, and next grow try setting up a hydroponic system of some kind (the ebb/flow method we talked about earlier is a better option than DWC for growing more plants in a smaller space and including a ScroG/SoG methods but more susceptible, again, to rot and disease in the root zone since the roots may be exposed to light and run on the same reservoir - disease and rot will spread across all plants if one has it). Good luck and happy growing :)
