hello .... we have been working with system that detects moisture and activates pump when medium moisture drops. It is adjustable to differnt moisture levels. We are considering choosing 1-2 people per forum to test and log said object. One can debate that its better to use timers for hydro. But if name of game is to pull oxygen to root zone is it? As far as soil goes not many
people can use timer successfully so this
product is excellent choice for automation.
