When a plant isn't thriving, most people look at water and light. But the pot plays a much larger role than many realize. It determines how quickly the soil dries, how much air the roots get, the risk of root rot, and how often you need to water.
If you choose a pot that suits the plant, everything else becomes much easier. In this guide, we'll go through drainage, size, and material step by step, concluding with specific recommendations for different types of plant owners and where a pot like the Side Level Planter can be a good choice.
Drainage: The Secret to Healthy Roots
Should there be a hole in the bottom?
In short, yes. The drainage hole at the bottom is not just an insignificant detail. It is most often the difference between a thriving houseplant and a sad, overwatered plant with root rot. A drainage hole ensures that excess water can drain out, so the roots get the vital balance between water and oxygen.
When you water plants in a regular pot with a hole, the water that the plant cannot absorb runs out at the bottom. Here it is crucial that you use a saucer for the flowerpot, and it is even more important that you remember to empty it! If you don't, the soil will just soak up the water again, and the roots will end up drowning.
In a pot completely without a drainage hole, on the other hand, the entire volume of water is trapped. Even a small splash of too much water can slowly accumulate into an invisible lake at the bottom. The roots suffocate without oxygen, and the worst part is that you have no chance of seeing it until the damage is done and the plant is drooping.
Most ordinary pots have drainage holes, but that is not enough in itself. There must be enough holes, and they must be large enough for the water to drain away easily. If the holes are too small or too few, the drainage will not work as it should.

How to use cachepots correctly and why it's a hassle
Decorative cachepots without a drainage hole at the bottom are extremely popular because they look fantastic in any decor. However, they are also most likely the primary reason why so many people kill their plants. They are, after all, only intended as outer pots.
If you want to use a regular cachepot correctly, it requires a bit of a ritual.
- You must leave the plant in its ugly plastic inner pot with drainage holes.
- Every time you water, you must lift the plant out of the cachepot.
- You must water it over the sink and let it drain completely for 15 to 20 minutes.
- Only then can you place it back in the decorative cachepot.
This is the only sure method if you want to avoid hidden water at the bottom. But let's be honest. Who has time to drag all the plants in the house to the kitchen sink every week? Planting directly into a pot without a hole is even riskier, as it requires almost superhuman precision when watering.
When does a plant pot without a drainage hole make sense?
A classic planter without a hole in the bottom can be incredibly beautiful in your decor, but it requires great care if you want to avoid an overwatered plant. In practice, it only works optimally:
- When the plant is in a plastic inner pot with drainage holes, so excess water can drain away.
- When you have 100% control over plant watering and know exactly how little water the species requires.
- When you consistently remember to empty the bottom of water so the roots never sit in standing water.
For most busy plant owners, a pot with drainage holes – or even better: a closed system with a water level indicator – is by far the most forgiving solution. It eliminates the risk of hidden water and provides the roots with the oxygen they need.

The size of your plant pot: Why most people choose incorrectly
When we shop for indoor plant pots, we often choose with our eyes instead of looking at the root ball. A large, beautiful plant pot might seem like the logical choice to fill a corner of the living room, but pot size isn't about aesthetics. It's about the vital balance between moisture and roots.
- The pot that's too small: The soil dries out too quickly. It becomes rock hard, water runs straight through, and the plant suffers from drought stress, no matter how often you water it.
- The pot that's too large: Here, there's so much soil that moisture lingers for days. The roots are constantly wet, lose oxygen, and slowly begin to rot. This is often the primary reason why people frustratedly search for: "Why are my plant's leaves turning yellow?".
The golden rule: Only go up 2 to 3 cm in diameter for small plants when repotting. Plants prefer to live a little snugly rather than drown in excess, wet soil.
Choosing the right material for your indoor plant pots
Terracotta, plastic, ceramic, or bioplastic. The material you choose for your plant directly affects how quickly the soil dries out, how heavy the pot is, and how robust it is in a busy everyday life.
Terracotta
Terracotta is a very porous material that absorbs moisture. This means that the soil dries out much faster, and more air reaches the roots. It is an excellent choice for easy houseplants that thrive best in drought, such as succulents and cacti.
Advantages of terracotta
- Ensures good drainage and plenty of air for the roots
- Ideal for plant types that prefer to dry out completely between waterings
- Gives a classic and rustic look to the home
Disadvantages of terracotta
- The soil dries out very quickly, forcing you to water much more often
- The material is very heavy and can easily break if it receives a small knock
Plastic
Plastic pots retain moisture significantly better and are incredibly easy to move around the living room. Plastic is often considered one of the most practical materials when it comes to large indoor plant pots, especially for beginners who want to avoid stress.
Advantages of plastic
- Retains moisture incredibly well, so you don't have to water constantly
- Practically lightweight and almost impossible to break
- Much more durable in everyday life than traditional ceramics and terracotta
Disadvantages of plastic
- Can unfortunately often look cheap and less exclusive in a modern interior
Glass and metal
Glass pots without drainage holes and beautiful metal containers are most often used purely for decoration. The problem is that they quickly become too wet or too hot inside. They are almost never the best choice for direct planting if you want to ensure a healthy root system.
Bioplastic and modern composite materials
Bio-based plastics and new composite materials now combine the best of both worlds. You get the benefits of lightweight and moisture-retaining plastic, but with a much smaller climate footprint and a more attractive design. These materials also allow for smart integrated features, such as a built-in water reservoir and clear indicators.
This is precisely where the innovative Moii pot stands out. It is produced from a bio-based material and functions as the market's smartest self-watering pots. It combines full control over your daily plant watering with an ingenious visual indicator on the side of the pot. It behaves functionally like a modern lightweight pot, but with a sleek matte design that fits perfectly into the Scandinavian home. So, you get the beautiful aesthetic, while the pot practically does all the hard work for you.
Self-watering pots are the simplest way to get healthier plants
Self-watering pots have proven to be one of the most effective solutions for your houseplants in recent years. When water comes from below, the roots draw exactly the amount of water they need, and the soil is allowed to breathe. This results in significantly healthier plants and far fewer mistakes.
The latest data from reviews in 2024 and 2025 speak for themselves:
- A full 92 percent experience healthier and faster-growing plants.
- The watering interval increases from every three days to just every fourteen to twenty-one days.
- Cases of root rot from an overwatered plant decrease by about 80 percent.
- Plants like peace lilies and pothos often grow to double their size in a single year.
For many plant owners, however, the practical difference in everyday life is even more important:
- You get completely automatic watering of plants during holidays and can safely travel for 10 to 30 days without needing a plant sitter.
- You completely avoid wet saucers and annoying water spills on the floor.
- It is ideal for a busy everyday life where your calendar is full and you don't always remember to water.
These smart pots may not be perfect for desert cacti, but for most other plants, they provide a more stable moisture balance and make plant care infinitely easier. If you combine all of this with the Moii pot's visual water level indicator, you have suddenly created the ultimate conditions for easy houseplants in your home. You no longer have to guess, because the pot tells you exactly what the plant needs.
The Moii self-watering pot and the big picture
The innovative Moii self-watering pot was developed based on the very problems that recur in hundreds of frustrated threads on Reddit, in articles, and in reviews of ordinary pots. The pain points are clear:
- You simply cannot see how much water is stored at the bottom of your flowerpot.
- You are constantly in doubt as to whether the roots are getting too much or too little water.
- Many traditional self-watering pots make the soil too wet at the top, which causes mold and attracts fungus gnats.
Instead of hiding the water, the Moii pot makes it visible. The roots absorb water from below, while the soil surface is allowed to dry out slightly. The clever indicator on the side of the pot clearly shows when the reservoir is empty. You can read it with a single glance without having to lift the pot, feel deep into the soil, or use a cumbersome moisture meter.
It naturally doesn't replace all other plant care, but it eliminates one of the absolute biggest sources of daily doubt: the fear of an overwatered plant.
What to choose for your home
Here are our specific recommendations based on your habits.
