Product Specs 

  • Pots: This device can water up to one pot.
  • Flow Rate: There is no flow rate.

As much as we tend to our personal gardens, we forget how naturally self-sustaining plants can be. Given the right environment and conditions, they’ll mostly take care of themselves. This 8-inch self-watering and self-aerating pot from HBServices USA offers an easy way to maintain the environment plants need. The container is designed with hollow legs that keep the plant above water while providing the perfect path for the soil to suck up as much—or as little—moisture as it needs.

Because you water your plants from the bottom-up instead of the top-down, there’s far less risk of over-watering. And customers agree, saying that these pots make it easy to keep plants at the right moisture level and that they love the modern design. The biggest drawback is that the self-watering spigot doesn’t always stay in place and can make refilling awkward.

  • Pricey for a single pot
  • Spigot doesn’t stay in place

How we chose the best watering systems

Plant care is sometimes more complex than it needs to be, so our research was all about finding options that offered easy and reliable hydration. But that means different things for different people. So, we looked at both automated and manual systems with an eye on cost, design, output, and ease of use.

The goal of investing in one of these systems is to lessen the frequency of watering and make it so that forgetting to do so isn’t a death sentence for your plants. We looked to customer reviews to make sure each model actually delivered on that promise.

Who this automatic drip irrigation is for

Automated watering is for every level of indoor gardener. Whether you’re just trying to keep a single plant alive on your windowsill or you’re caretaking an entire jungle in your kitchen, investing in a drip irrigation system can save you time, money, and a lot of stress.

Opt for a smaller option like a globe or spike if you only have a couple of plants. If you have a larger collection, then a full-fledged system like an automatic timer or programmable drip irrigation is best.

What to know before you buy a drip irrigation kit 

No one wants to be a deadbeat plant parent, but life has a knack for getting in the way of best-laid plans. If you have trouble keeping your plants hydrated and happy, an automatic drip irrigation system can help you stay on top of your indoor gardening game. Just be sure to consider factors like size, water pressure, and user-friendly features before you press purchase—your plants will thank you.

Types of drip systems 

Drip irrigation systems come in all shapes and sizes, from basic kits to more advanced models with multiple lines of tubing. The type that you choose will largely depend on the size of your space, the number of plants that you’re growing, and how hands-on—or off—you want to be. Some systems offer the ultimate in convenience and automation, while others require more manual intervention. Getting a handle on all of your options will help you make the best choice for you and your plants.

Globes and spikes 

Globes and spikes, while not as automated as full-on systems, are great for those who need a little extra help with the watering department. Simply fill up the water reservoir and stick it in the soil. From there, the spikes will slowly release water as needed.  

These inexpensive systems are best for beginner gardeners who don’t want to mess with complex installations. However, they do require refills every few weeks, depending on the plant.

Automatic drip water systems 

Automatic drip water systems are best for larger, more established indoor gardens. These methods use a network of tubes and emitters that slowly drip water into the soil based on a set schedule. More advanced models can make adjustments based on temperature, sunlight, and humidity. 

The pros are obviously convenience and accuracy, but there are risks to set-it-and-forget-it watering. Putting your plants’ health in the hands of a machine could lead to overwatering and flooding.

Self-watering planters 

Self-watering planters are a lifesaver for the busiest of plant parents. These containers are like globes and spikes in that they feature built-in reservoirs that store and slowly distribute water to the soil as needed. However, they tend to have larger capacities and require fewer refills.

While you do have to remember your refills, these planters eliminate the need for additional tubing or complex installations.

Automation features 

How passive do you want your watering schedule to be? Maybe all you need is a simple timer that sets off the irrigation system at regular intervals. Or perhaps you’d like to take your automation one step further by connecting your system to a soil sensor that detects when and how much water to give your plants.

If you’re a tech-savvy gardener, you’ll probably want a system that can be controlled with your smartphone. This way, you can adjust the schedule and check up on the progress of your plants from anywhere in the world.


Unfortunately, even the most high-tech irrigation systems are limited in how much water they can hold. Most manufacturers will include how many pots a system can water on the label, but you’ll still have to take into account the size of your containers.

When in doubt, it’s best to err on the side of caution and buy a bigger irrigation system than you think you need. This way, you won’t have to worry about running out of water when your plants need it the most.

Water flow 

Perhaps the most crucial element to consider is water flow. Too fast of a rate can drown your plants, while too slow can dehydrate them. Systems like globes, spikes, and self-watering planters tend to have consistent rates that don’t need to be messed with. 

But if you have finicky or high-maintenance plants, you’ll want a system that allows you to control the flow rate. This way, you can adjust it based on the size of your containers and the needs of your plants. Just know that the more customization a system has, the more expensive it tends to be. 

The advantages of using a drip irrigation system 

You don’t have to be a master gardener to understand the importance of water for your plants. But when it comes to keeping indoor gardens hydrated, too much or too little can lead to disaster. 

Drip irrigation systems are an efficient and cost-effective way to keep your indoor plants healthy all year round. By slowly releasing water at regular intervals, these systems save you time and resources while ensuring that your plants have the best possible chance of survival. Plus, they also prevent disease by reducing the amount of water contact with the foliage.

But perhaps the best part about drip irrigation systems is their convenience and accuracy. With a single installation and minimal maintenance, these systems allow you to set it and forget it and trust that your plants are receiving the best care. 

  • They prevent diseases by keeping your plants’ leaves dry.
  • They are easy to install and maintain, saving you time and money.
  • They provide an accurate and consistent flow rate so your plants get the best possible care.

Tips for using an automatic watering system 

There’s not a lot of know-how required to operate an automatic irrigation system, but there are a few things you can do to ensure you’re getting the most out of this handy machine. For starters, set a reminder in your phone or schedule an event in your calendar to refill the reservoir. How frequently you do that will depend on the size of your system, but creating some sort of reminder will prevent your plants from going thirsty. 

When you’re refilling the reservoir, it’s also a good idea to give it a little scrub. Residue and minerals can build up over time, so regular cleaning is essential to keeping the water fresh. And finally, before you purchase a system, make sure that any hoses are long enough to reach all of the plants you need to water. The last thing you want is to set everything up only to find out that the hose doesn’t quite reach your beloved fiddle-leaf fig. 

  • Set a reminder to refill your reservoir.
  • Clean the reservoir regularly to keep the water fresh.
  • Make sure the hoses are long enough to reach all of your plants.


Getting a handle on your plants’ watering schedule can seem daunting, especially if you’re a beginner. But with the best drip irrigation system for indoor plants, you can keep your foliage hydrated and healthy all year round. To help you out, we’ve outlined some frequently asked questions below to make sure you have everything you need to get started.

Does drip irrigation work for potted plants?

Yes—drip irrigation systems are great for potted plants, as they provide a consistent and controlled water flow rate that helps keep your plants hydrated.

How long should I run drip irrigation for potted plants?

This answer really depends on your plants, but drip irrigation systems usually run for about an hour per week.

Should I run drip irrigation every day?

No—it’s best to limit the use of your drip irrigation system to once a week or less, as over-watering can cause root rot.
