I read about this and I'm wondering if it's possible and effective. I have various containers of many sizes and shapes. My round ones range in size from 1-1/2 gallons

to 5 gallons and the smallest ones are about 8" to 10"

in diameter; the others are three that are 14" in diameter

and one 16" in diameter.

My other ones are rectangular in shape

and are as follows...

small (10 gallon)

medium (18 gallons)

large (30 gallons)

Since I'm using multiple containers how can I set up a drip irrigation system for them all with the milk jugs?

Also how many milk jugs would I put per container for drip irrigation? I don't know if I'm going to set up a system for all of my containers, or just use "x amount of milk jugs" (how many would depend on the size of the container). However I haven't decided which method to use yet.
