Free DIY Automatic Plant Watering System Options

Automatic Plant Watering System DIY

You don’t have to break the bank to taste the awesomeness of some watering systems.

If you are on a tight budget, you can easily make your own automatic plant watering system at home.

The cost can be anywhere between free to a few dollars depending on what you want to achieve.

To start you off, here are some options to try out on your own.

Notably, most of the DIY watering systems are primarily made to be used on indoor container plants.

1. From plastic bags

It is very easy to make an automatic plant watering system from a couple of plastic bags.

All you need is some threads, a sharp needle, and of course, several plastic bags depending on the number of plants.

Now, once you have these materials, it’s time to make the system.

Insert the thread inside the needle hole as you would do when sewing. The thread will serve as a wick.

Pierce through the plastic bag from inside out.

Make a knot at the end of the thread and pull the needle further out so that the knot attaches to the bag.

Remove the needle and leave the thread hanging on to your planter around the root zone.

Fill the bag with water and properly tie the top.

Once you’ve filled the bag hang it a little bit above your plant and the water will start dripping on the media giving your plants the much-needed moisture.

You already have the simplest, cheapest plant watering system that will allow you to take a 2-3 weeks’ vacation.

Repeat the same for all of your indoor plants.

2. From recycled plastic bottles

This one is by far the most common method for making an automatic plant watering system.

Instead of throwing away empty plastic bottles and tampering them, you can recycle them into a self-watering planter for the indoor plants.

Here’s how,

For this exercise, you’ll need empty plastic bottles, a sharp scissor or anything you can use to cut the bottle, cotton thread/strings, and a suitable growing media (pot soil) preferably pumice or coco peat.

There are several approaches to making a self-watering planter using empty plastic bottles, but I’m going to focus on common three.

The first one is very simple.

All you need is to make several tiny perforations on the bottle, fill it with water, close the bottle tightly, and bury it upside-down into the growing media as illustrated below.

Don't forget to make a bigger hole at the bottom of the bottle so that you can occasionally top-up the water.

The second approach is more or less the same as the first one.

The only difference is that instead of burying the bottle into the planter upside down, you bury it upright without closing the bottle.

You can add water whenever necessary as the image below suggests.

The last approach is used mostly in seed starter pot planters for salad vegetables such as lettuce.

First, you are required to cut the bottle in the middle using a scissor. Make two to three holes on the top part and tie the cotton thread.

Once done, fill the bottom part with 25% water.

Invert the top part onto the bottom one, before filling it with your preferred pot soil such that the cotton thread touches the water and connects it to the media.

See the figure below.

If you don’t have plastic bottles but have wine bottles instead, here’s what to do.

3. Automatic plant watering system from recycled wine bottles

Probably one of the simplest method.

Just fill the bottle with water and invert it onto the growing media around the root zone as shown in the photo below.

Most of these DIY watering ideas are at times convenient and will save you the trouble of having to worry when to do the next watering.

I’ve just shared a few of the DIY self-watering planters.

However, there are several problems with these improvised self-watering planters.

One of them is that you cannot control the frequency at which water is applied to the soil.

This makes the soil muddy and could probably stress out your plants or even encourage prevalence of fungal diseases.

Not to mention their inefficient use of water.

If you have many plants to water using these methods, brace yourself for a higher water bill on wasted resources.

That's why I recommend to use incorporate a few options that cost some money. With those options you have better control of the water usage as well as enhanced efficiency.

But if you're on a tight budget, establishing a DIY watering system could be the way to go initially.


There, you have it.

It’s time to stop procrastinating and choose the best automatic plant watering system that suits you.

Make watering your beautiful plants a priority since just like me and you water is life, and your crop needs it.

As usual, I always like to remind you not to close the post without ever taking notes.

Write down two to three watering systems that you feel will best represent your needs and start working on them right away.

That’s the only way to ensure that all the time you’ve devoted to reading blog post after another, provides some meaningful value to your life.
