FOAM PUMP: I need some tech stats...
Does anyone know what the preferred Gallons per hour (cups, liters whatever) per plant should be bubbling up to the top of a bubbleponic system?
I am building a system that is using a "Foam Pump" instead of the drip irrigation and pump system and want to be able to set my flow rate correctly.
If you are curious what a foam pump is read on:
Take a piece of 3/4 (or 1/2 but I haven't tried it yet) PVC pipe and cut it about 1" longer than your tank is tall.
Stick the air hose from your aquarium pump into one end and push that end into the bottom of your tank.
Foam comes out the top.
To adjust the amount of foam push the airline further up the tube to decrease the flow and pull it lower towards the bottom to increase the flow.
I've tried it. It works. Just bubbly foam. I want to try it with a 1/2" airstone in 3/4" pipe. I'll bet it looks like club soda coming out.
No heat from the pump to deal with. In fact I'm putting a heater in mine to keep it at 77f.
