How to make a self-watering pot.
Self-Watering pots are great. Your plant will have water as it needs it, and extra water will be easily and effectively drained out. Here are the materials that you will need.
2 Five gallon food grade buckets
1 1/4″ to 1/2″ PVC pipe about 20-25″ tall depending on the specifications of your containers.
1 small mesh pot (These can be found in most hydroponic stores or your local garden store.) You can also use a the bottom of a soda bottle. If you use a soda bottle drill a bunch of holes in it.
So first you need to cut a hole in the bottom of one of the buckets. This will be the bucket that will hold dirt. The hold that you are cutting should be in the center and just big enough for the mesh pot to fit into.
Next you will want to drill a hole that is big enough for your pipe. Make this hole close to the edge of the bucket.
Drill a bunch of 1/4″ inch holes all around the bottom of this bucket. This will allow water to pass too and from the dirt and reservoir.
On your pipe you need to either make small holes around the bottom of the pipe, or one large one at the very bottom creating a C at the bottom of the pipe. You need holes so water can enter, and leave the reservoir. With out these holes you will just have two buckets setting on top of each other.
Now you need to put the pot and pipe in the holes that you have created. Place this bucket on top of the bucket that you have not drilled. Some people like to fill the dirt chamber about an inch with small rocks to keep the soil more in the main chamber. This is optional.
Fill your main chamber with dirt, and your plant at the top. Your pipe should be sticking about 2-5 inches above the soil. If it is more that is okay too. Just make sure your pipe clears the dirt enough with some extra left over.
Pour water into the pipe until the water does not go down the pipe anymore.
There you go, you just made your own self-watering container. You shouldn’t have troubles with your buckets resting on each others bottoms as the rims of each bucket allow for there to be a cavity. If you are having this problem simply cut the pipe and make it join at the hole in the reservoir with a threaded PVC connector.
I hope this helps. If you have any questions please feel free to ask.
