Default Drip irrigation, not pressurized

Anyone know of the feasibility of a drip irrigation system feeding out
of some 5 gallon buckets into some tubing?

If I get this community garden space, I only want to go to it once a
week because of the distance.

Do you think some 5 gallons buckets, maybe 3 feet off the ground, could
supply a weeks worth of water? Mostly, do you think the drip mechanism
would work without the city water pressure behind it?

Any ideas?

What area does it need to cover? Under what conditions?

I might have a 20x30' plot, in ground plants. San Jose, Ca, Bay Area
summer.



If all you want is a slow drip feed the fact that it is gravity only wouldn't
be a problem, you might find that you are crimping the hoses to stop it all
running out the first day.

However for that area you are going to need quite a few 5 gallon buckets to
keep that going for a week in summer. I cannot be bothered looking up the USA
gallon's volume in real units (:-) but my guess is that you are going to need
about 400-500 gallons to put an inch on the plot. Whether that is enough
depends on what your summer is like and the type of soil and the type of
plants. There are plenty of cases where it would not be enough for good
growth unless it also rained.

I suggest you do your sums and work out what rate would be right. I suspect 5
gal buckets will not be worth it.

I know I'm new at this, but you're the second person to make
calculations based on covering the WHOLE plot with an inch of water.
Doesn't a drip system negate that need?
