I was seeing the future ray tank today and i saw the plants working

How? The quantity of air bubles getting out of the plants was incredible.
Off course that there is no current in my tanks, because i don't have pumps. But in my ray tank i'm planning on doing two things that i don't do in the others. The first one is the eating system. You will see it in the end of Summer, I hope

All this with solar system and wind system
