Window Farm Update: Victory Against Algae!

I’m pleased to report that we’ve now gone a week without any green slimy stuff showing up in our nutrient reservoir, so I think I can safely declare that keeping the reservoir in the dark is the solution.

I am less convinced about my alternative pumping system, using the venturi effect instead of lifting water with bubbles. It works, but takes a lot of tuning to get the right flow rate, and at present, isn’t working very efficiently. Still, the plants are surviving, so it’ll do for now…

More pictures to come…
