Do you guys think something like this will work? I have a pump with a reservoir built in, as well as a float switch. What i'd like to do is have a main holding tank above my plants on a shelf, with the individual drippers coming off of the bottom, to each plant, feeding by gravity through 1/4 vinyl tubing to the plants.

After it hits the plants it will flow down through drains in each grow pot, down to a pump I have below the plants, collecting in the pumps reservoir until it kicks on the pump, and is pushed back up to the holding tank at the top again.
The pump holds about a gallon, so i'd expect it to kick on every half hour or so give or take ten minutes. The pump is a condensate pump I use for air conditioning installs to collect condensation, so its rated to run alot, and it made of PVC.

I'm planning a trip to a hydro shop in about 2-3 weeks, and I could pick up a normal pump and drippers and do it the typical way, but since I have this stuff already, i'm dying to give it a go What do ya think?
