Initially, I only planned to have a pump connected to a Wi-Fi outlet for this setup.
Over time, though, I’ve added two USB UV LEDs, a second pump for brassing, and, most recently, an oxygenator. As a result, the wiring has become quite messy :
It’s time to upgrade this, with a 4-relay Wi-Fi board and some 3D-printed casings !
I have a moisture problem. The roots that are completely submerged are dying. The plants still look okay, but I think this will become a problem in the future.
I have read that this could be due to root asphyxiation if the water is not sufficiently oxygenated. I will install this aquarium oxygenator in the water tank to try to fix it.
The more time passes, the less confident I am that the small foam cubes are a good idea. It seems like the roots can't properly 'grip' them, and the plants are slowly falling out of the bucket over time.
