Picture of Easy Self Watering Plant Container
All it takes is a water bottle and swiss army knife to make this wonderful self watering container. It operates just like an Earthbox. Its very easy to put together and is very low maintenance. It'll make growing plants so easy you'll want to grow an entire garden.

Step 1: Gathering Supplies

This is a very easy build, and many ways to modify on to it which i will show after. So as for the supplies you'll need.

1. Water Bottle
I suggest getting one that is shaped like an hour glass, they tend to hold up better and provide and excellent base to build upon.

2. Swiss army knife
I used the tiny army knife in this instructable, but I found the larger red army knife better because of its reamer. It makes the hole punching part much easier.

as for the mods, you'll need:

black heavy trash bag

Step 2: Prep Your Bottle

Dump the water out, drink it, or save it so that you start out with an empty bottle. Also, it's not really necessary, but remove the label (makes it look nicer).

Step 3: Cutting The Bottle

Now that your bottle is looking nice and ready, cut the bottle about half way. I cut mine at the top of where the bottle dips, there was a very distinct edge. If your finding it hard to cut a straight line, tape a marker down and spin the bottle where you plan on cutting it. Then you'll have a nice guide line to cut on.

Step 4: Poke Holes

This is where the reamer tool on the knife comes in handy a lot, I had to use the scissors because i lost my good pocket knife just before making this. Poke holes in the cap and about an inch down the top. I punched my holes like the five side of a dice on the cap, then 8 holes just under the cap, and four more below that. You want the holes small enough so that soil doesn't fall through, but large enough to drain water.

I took a nestle 23.7 fl oz bottle with a fliptop -> cut it in half -> turned the top half upside down and cut the flip cap off. The mouthpiece already had holes so it turned out great!

thank you for this instructable greatchrismyster! I rushed to make my own out in my garden and I will use this technique in my school garden. I always get worried my vegetables dry up during the weekend. I can't drive during the weekend to come water coz i live far from school. the students are loving the garden, so since it's very hot here, i will try your technique, plus we are recycling water bottles already.

thanks to pyromomma for the tip about the coton thread tip! ingenious

Great idea but may I ask what plant that is you are growing? Very intriguing looking. Thanks for a good instructable!

they are a mixture of different types of sunflowers, some are dwarf, others are the 5 to 6 foot kind that have been dwarfed because of the pot

Nice job! I love to make these. A hint for plants that only like to be barely moist: A strip of cotton sheeting or a length of cotton string threaded through one of the holes in the cap before planting will help slowly wick the water into the soil. The cap does not have to touch the water. Hint 2: Once your seeds are growing well, transplant to a larger container - make a self watering one out of a larger "bottle" like a plastic gallon milk jug or 2 gallon water jug. Hint 3: Dilute a very tiny bit of water-soluble fertilizer (like Miracle Fro, etc) in the water once the seeds have grown 3-4 leaves. Good instructions, thank you!

Nice instructable, good for recycling water bottles too.

thanks, i'm an avid gardener now, mostly growing sunflowers for my girlfriend, these pots have worked perfectly for me, i just start the seed and put them in these pots, they grow themselves, the water has always stayed moist without roting the roots, and to acknowledge the environment, cant grow plants when you're polluting them.
