Through this DIY you will be able to build a self-watering planter, after building this you will not have to worry about dead succulents or worry about watering your plants when you’re on a vacation, your planter will do that for you. Another advantage of this planter is that you won’t be over watering your pant and killing it in the process, your plant will absorb the amount it needs.

Automotive primer (to smooth prints)
Before beginning with this DIY, you will have to understand the design for the planter. The planter will have two parts, a water reservoir at the bottom and a pot on the top, there will be a wick that will placed to connect the two, this will allow water to be absorbed into the pot. The planter that is shown in this DIY is made with a 3D printer however you can follow the same method and make it out of wood, however, you will then need t make it in a square shape.
For this step you will need to make the form. If you are 3D printing the form you will need to make a silicone mould for it, you can follow the link provided for the measurements.. Since 3D print forms are not perfect for mould making so you will need to smooth it out with some autofill primer and it will need lots of sanding.
Now we can get to making the form, for this you will need to put together all the pieces, apply a thin layer of glue and place the 3D between a pipe on a base, the pipe should be larger than the 3D form and should be of 2 halves so that it is easy to remove it later. You can secure the outer pipe with some rubber bands and you a lot of tape at the bottom of the base and the sides of the pipe, this is done to prevent the silicone from any leakage.
Once you have placed everything in place you will need to use a two-part silicone to make the mould. You can put each amount in separate containers and the mix them together in a bigger container, mix them until both the colours form a different new colour. Pour the mixture into the mould, tap it on the side to get rid of any bubbles that might have been formed and leave it to dry up overnight until it is ready, once it is ready you will need to take the moulds apart, this might be challenging and could be a process where you end up damaging the silicone, if you do end up damaging the silicone all you have to do is patch up the damaged parts with the leftover silicone mixture.
Do the same with the reservoir part of the planter.
Now you will have to prepare the concrete. Put some concrete into a container and then pour some water you will want it to look like a sandy pancake batter. Once your mixture is of the right consistency you can pour it into the mould, just like the silicone you will need to tap it on the side so that the mixture settles into the mould and to get rid of any bubbles. Leave it for a day so that it can dry up.
Once it has dried up and removed out of the mould, you will have to smoothen the surface. Once you are satisfied with the surface it is time to make the concrete planter. For this you will need to take the pot of the planter and drill two holes at the base of the pot. Then you will need to water proof the pot and the reservoir with some concrete sealer, you can use a paint brush for this, waterproof it on the inside as well as on the outside. You will then pass through a rope into the holes, leave enough rope for it to reach the reservoir, this will act as a wick. You can burn the ends of the rope so that it doesn’t fray.
Once you are satisfied with it you can place the pot over the reservoir. Add some mud into it and transfer your plant into the pot and fill the reservoir with water. With this you are done, you just built a self-watering planter and do not need to worry about forgetting to water your plants.
