I will guess that you will use a hose for your water source. If you have a home depot near you they have a kit just for your situation that will take all the guesswork out of your project.

BG,

Drip kits are in all the big box stores and hardware stores. The internet is also a source. See the following link garnered by googling irrigation drip kits.

The main challenge is the fitting from your water source as Mike points out. The rest is just buying the size and type of kit you want(method of applying water).

Their shipping costs are cheap for the lightweight stuff (emitters, couplers, etc). If you ever need heaver hoses and stuff, you're probably better off getting that at the local home improvement stores.

Those kits are pretty nice to start out with. You can always add to it as your situation changes.

As far as simplest program. The drip tape, t-tape and soaker hoses are the easiest because you don't have to fuss with all the individual emitters. Of course that takes some of the flexibility out of things, but it's not a bad way to go.

Drip kits are a great way to begin with a new dripper system. If you need, you can always add more components later on. Your local hardware store should have this stuff and you can always find good deals on Amazon, eBay and other websites.
