DIY Ebb and Flow setup questions
I am looking at building an Ebb and Flow/Flood and Drain system for two blueberry plants. Any suggestions/advice would be welcome, but I have a specific question too.
I get that the pump floods the plant for 30 mins 4 times a day if I use expanded clay pellets (which seems to be the recommended medium), but Im not clear on how the pot fills without overfilling, and then drains after it sits full for 30 minutes?
I am wanting to make a system myself to save money, but am not sure how to overcome this hurdle. Seems to me the pump would keep pumping until the timer cuts it, and the drain would keep draining, so it can't possibly stay full for 30 minutes and then drain.
Solutions, ideas, or something I'm missing?
