I have a multiple rooftop container garden that is right now taking me
about 90 minutes to water averaging around 150 gallons of water per day.

Hi
I too have a roofgarden, but nowhere near as big as yours so I don't have an
automatic system :~)

Leaky pipe is OK but will 'leak' all along their length.

I am in Europe so don't know what's available in the US. There are some
links on my site about watering, but I'd guess that standing your pots in
drip trays would maybe mean you'd only need to water maybe every three days?

Depends of course where you are and how hot it is.
