Great minds think alike ha ha. For a while now I'd been mulling over a means of having the bubble cloner tank refilled from a reservoir setup, but nothing came to mind in concrete terms just yet. Different story for my outdoor grow though. I recently started gathering the parts to set up a self-watering system complete with solar panels, a timer, and a hidden car battery powering a submersible water pump in a nearby creek that would be connected to the grow by a buried pvc pipeline. That's another topic for another day, before I get to rambling here again.
