Last weekend we had a heavy rain storm come through. It actually filled my tomato's reservoir so had to guess how much food to put in. But worse, it tripped the circuit that powers the pump. So, when I got out there Tuesday some of the plants on the tower were wilting. Got the circuit back up and they started to bounce back. But then we got another bought of rain and it tripped again. So, now I've got a raspberry pi sitting out there on the same circuit just logging every 5 minutes that it is up. So, now I'll have a faster way to tell if it tripped and when.
The tomatoes already have some long ass roots so they don't really need the pump anymore. It just helps the water from getting stagnate and helps keep it oxygenated.
