I needed a watering system because I have trouble getting around due to health issues and it's really not fair to my spawn that he be the one to do the watering every day.  Fourteen year old boys want to be in a swimming pool, not standing in the sun providing cool refreshment to a container garden.

My husband says we have all but one part necessary to build a normal drip system but because he is an incredible procrastinator and we're low on cash I decided to see what I could find online.

I started here, of course.  My favorite is "IcePop Drip Irrigation" by marcintosh but because I am container gardening, I don't have quite the room necessary in each container to lay a bottle down.  Others that I saw would require creating some kind of hanging bottle system which I wanted to avoid as I want my little garden to look as natural as possible and you just can't get that with plastic bottles dangling around.  

My inspiration for this instructable came from Gayla Sanders at You Grow Girl.  Mine is different only in that I put a different number of holes in my lids and used various sizes of bottles based on the size of the planter they'll be used in.  Oh, and I didn't use a serrated knife to cut the bottoms from my bottles because I figured that scissors would work more quickly and easily.

What you will need:

(List based on making one waterer.  Multiply appropriately for however many you need.)

20 ounce plastic bottle with lid (soda, or juice washed out, if it was water, no need of course.)
Safety glasses
Sharp paring knife
Kitchen Shears
Drill
1/16" drill bit
Solid surface on which to do your drilling


So gather your supplies and click ahead to the first step.

(Picture with the finished product nestled amongst the greenery of one of my plants coming soon.)

Step 1: Stabby Stabby Snip Snip (Or: Preparing the Bottles)

In step one we deal with the bottle.

First, put on your safety goggles.  No, they're not as sexy as a pirate eye-patch, but you want a drip system, not a hospital bill, right?  Right!

On your firm surface (mine is an old Formica covered drawer front on the kitchen table) firmly hold the bottle in one hand and set the tip of the knife at a straight up and down angle, near the end of the bottle.  Quickly and firmly stab the bottle to avoid the bottle crumpling under the pressure of a slow stab.  Do NOT rear back Psycho style shrieking, "SKREE! SKREE! SKREE!" When you do this.  You'll only freak out your neighbors and probably end up stabbing yourself.  We're still trying to avoid that hospital visit.

After the hole has been made with the knife, work the bottom blade of your shears into the hole and cut your way around until the bottom is off.
Hi Rowan. One of the reasons this system drains so fast is the open top. If you try joining two bottles together (ie the tops of two bottles) with holes in both tops, the closing of the surface top slows the drainage rate and prevents flooding. There is some technical name to this action. Alternatively, pierce the bottom of an intact bottle with 3 needle holes, bury and fill, then screw on the top. This also works allowing too. I get 3-4 days out of mine this way. I zip along and unscrew all tops, then water the pots and fill the bottles. Cuts watering down from daily to 4 daily.
Excellent idea! I'll have to give that a shot.
I like cutting the whole bottom off to make it easy to re-fill. Great idea. Big plus also if it rains it fills itself and will still slowly water your plants when the rain ends. Thanks.
Very nice, had you seen <a href="https://www.instructables.com/id/Use-those-bottles-to-water-your-garden-during-dry-/" rel="nofollow">my (somewhat more complicated) version </a>of this?
I have now! :) I like the idea of burying the whole bottle, too. There are lots of variations for this project! Weirdly, I didn't see yours or Kiteman's when I did this one. I tried all kinds of search terms but nothing brought either of you up. Now I feel like a copy cat! :(
