Hi I am about to build this design you layout here: http://www.hydroponics-simplified.com/support-files/mini-ebb-and-flow-pdf.pdf

However, I have a nagging question I must ask before I make any cuts. I am wondering why the drain is so high up? I get it that it is to prevent overfill, but when I kill the pump and it is time for the water to drain, will it drain back thru the 1/2" inlet or the 3/4" overflow drain?

I am wondering, if it is the latter, then how will the tray ever drain completely?

Thanks very much for your reply. If all goes well I will have this kit running by Sunday. Woot, can't wait!

Answer from Stella/Simon:
hi Austen,

A very good question! I will be honest with you, when I first started out, and learning about ebb and flow, I had the exact same puzzling question in my mind.

Something no one ever tells you, and I guess I should put it into the directions is this:

While the plant tray is in the fill mode, the higher pipe is for overflow drain back into the reservoir, so solution won't overflow the sides of the tray. And guess what? Once the pump shuts off, all that nutrient solution drains back through the shorter pipe THROUGH THE PUMP, and back into the reservoir.

Hope this is answer your question :-) :-) :-)
And hope you have much fun and success with your new hydroponics project!

Hope this helps!
