One of the best parts about making self-watering containers for your garden is that it’s cheap. Most of the supplies needed are either already laying around the house or you can easily get in your neighborhood.

Container Within A Container and No Pipe

    Tools

  • Drill
  • 1/4″ bit
  • 3 1/2″ hole saw for metal and wood
  • 1 1/4″ hole saw for metal and wood
    Materials:

  • 2 food grade 5 gallon containers – 1 for planting container and 1 for reservoir container
  • 1/2 deli container for wicking basket
    Instructions On How to Make With 2 Containers and No Pipe

  • Use the 1/4″ drill bit to drill holes in the deli container.
  • Attach the 3 1/2″ hole saw attachment to the drill. Drill a hole in the bottom of the container. I’ve found drilling in a counter-clockwise direction to work best.
  • Reattach the 1/4″ drill bit and drill holes in the bottom of the planting container to allow for drainage.
  • Put the wicking basket in the middle of the reservoir container.
  • Place the planting container in the reservoir container aligning the wicking basket with the hole in the middle.
  • There will be a little space between the wicking basket and the planting container. You can duct tape the basket to the bottom of the container, but it’s not necessary.
  • Hold the containers up to the light. You should be able to see through the reservoir container where the planting container is. Using the 1 1/4″ hole saw, drill a hole 1/4″ in the reservoir container below where the planting container is.
  • This is the hole where you will water the plant from.
  • That’s it. You’re done!

    We drink water from copper pipes. We water plants with water from copper pipes. How is a copper pipe in the soil possibly going to harm the plant?
    $40 for a 10' piece of copper pipe? I could probably ship you that much copper pipe for way less than that. I think a 3/4″ 8' copper pipe here costs around $10.
    Either way, I think your containers are great. And recycling rocks!

    I'm with you Sylvana, but some haters have said that the pipe is bad for the roots of the plants. Either way, this is another low cost way to make the containers.

    People will always find a problem with something.

    *raises hand* Yay, that is so cool that you tried my idea and it worked!

  • Mike Lieberman

    Awesome. Thanks for the idea. Updated to give you credit for it.

    Good solution. You could also consider using PVC pipe instead of copper :)

    If I'm not mistaken, a 1″ x 10' PVC pipe is about $1. Certainly easier to cut than copper!

  • Mike Lieberman

    Yes, but there is the concern for the potentials of leaching into the water.

    Awesome idea! Thanks! I love the self-watering containers! I’ve done square foot gardening for years up in Michigan, but here in Vegas needed something different. I was afraid the plants would die from the heat combined with watering restrictions that keep us from watering during the day. I think the self-watering containers are what I’ve been looking for! I can move them out to get sun early in the day & pull them back under the covered porch before the heat of day hits…and don’t have to worry about them not getting the water they need during the day.

    I love your blog! Thanks!

    In London it’s dead easy to find PVC pipe for free from skips. I’ve got more than I know what to do with. I see your comment about leaching. I’m no expert but as PVC pipe is often used to carry drinking water I’m guessing it’s not too serious a problem.

    I hear ya, but just because it’s used doesn’t mean it’s not too serious of a problem. Look at GMOs, fluoride in water and a million other things…
