I also use the Chapin bucket irrigation kit. You can contact Richard Chapin at firstname.lastname@example.org.
The kit recommends that the bottom of the bucket be placed at least 1 meter (3.28 ft) from the ground, the kit uses 15 mil, 12" spacing and .5 GPM per 100 ft.flow at 10 PSI pressure tape. The kit includes 100 feet of drip tape, which can be used in 2, 50 feet rows, 4, 25 ft rows or 6, 16.5 ft rows. It works well at this reduced pressure (which is a bit less than 2 psi at the bucket outlet)
Chapin Watermatics also offers a 1/4 acre garden kit, that can water 20 rows, 100 ft long, using a 10 Gal per min flow.
The bucket kit uses a simple fine metal mesh covered rubber cap as a filter, the garden kit uses a filter/pressure regulator assembly designed to operate with tap or well water. If water is coming from a pond or stream or if there is algae or iron, they recommend using a sand media filter.
Hope this helps
(btw I am not associated with Chapin, but do like what they are doing)
