I remember watering these things was time consuming to say the least last year so this year I have taken 1 more step to getting everything sufficient enough to last at least a couple weeks without me. The tote holds about 15-20 gallons and has a submersible pump with a manifold run by a digital timer. It will take a day or 2 to get it "dialed in" but doing so will be easy. Only modification I have to make is once I get some more tubing I will run dedicated lines from the manifold instead of using a tee.
I would say the next/last step in the evolution of my infrastructure will be to build an actual bog.
