The Ultimate Terrarium Guide (And How to Choose the Right One)

There’s no need for a huge garden to have nature around you.

In some cases, all you need is a simple glass container, standing silently on your desk. Some greenery. Some life force. Something that requires no care—and yet improves your environment significantly. A terrarium does just that. I distinctly recall my experience making my first terrarium, assuming it wouldn’t last more than a week. But it did, and quite beautifully too. That’s when it struck me that terrariums were not only beautiful but also extremely convenient.

Why Are Terrariums So Special?

Terrariums are unique because they make their own little ecosystem, unlike normal house plants.

All the action happens in the terrarium itself, from the cycle of moisture to the circulation of air. You don’t need to constantly manage everything, just guide it along.

The “Low Effort” Secret (That Actually Works)

The secret most people miss is:

Terrariums create a self-watering system.

Water evaporates, condenses on the sides, and comes down into the soil. That's a closed system. You basically only need to adjust it when everything is set up.

Which is why terrariums are so easy to kill by beginner mistake, through overwatering. Not underwatering.

Choosing The Right Terrarium (Yes, It Does Matter That Much!)

Terrariums are not all made alike. Believe it or not, the process would be much easier with a good choice here. When you’re new at this, choose a pre-built solution such as a Complete Set of Eco-Water Grass Tank by Planted Pro. It’s the kind of terrarium where you don’t need to think about what plants would work well with each other and how they should be arranged, since it’s all done for you. If you favor something more compact and simple, consider choosing a moss-based terrarium, such as the Green Hills Moss Microlandscape.

It depends on you:

For the lush and extravagant? → Choose planted environments

For the minimalistic and peaceful? → You’re going to love moss terrariums!

Watering: Less Is Definitely Better

This is probably where people screw up the most.

Terrariums do not require constant watering. If you overwater them, you will damage them quickly. How to check? Only water when the soil doesn’t look dry. In the closed type, you can last a few weeks without watering at all!

Lighting: Make It Gentle and Indirect

Bright sunlight isn’t necessary—and it could actually be harmful.

Put your terrarium where it’s bright but doesn’t receive direct sunlight. Window placement is ideal. Or you can use an LED light if your lighting conditions aren’t favorable enough.

Is There Any Situation Where You Should Open It?

Sometimes, yes… Although terrariums are self-sustaining, opening them every now and then will help keep them from becoming too humid. It’s like refreshing something—nothing too regular.

Some Small Steps With Great Impacts

It doesn’t require a set schedule; just be aware:

1. Cut back any overgrowth

2. Prune dead leaves before they’re dead

3. Detect any abnormal odors (usually due to excess water)

4. Cleanliness and orderliness are all it takes, and that should be sufficient to keep it alive.

If You Want No Stress: Choose Moss!

Not everyone likes dealing with plants growing—and that’s perfectly okay.

When it comes to moss terrariums, they are arguably the simplest choice available. They are tidy, they don’t overgrow, and they still look great. Just set them up once and forget about them. That’s why many Planted Pro customers begin with moss landscapes before getting into more complicated arrangements.

A Small Gift Note

When you want to give something unique... here it comes. Terrariums are personalized. They have lasting value. Plus, it does not matter whether the recipient has gardening skills or not. It is indeed an unusual gift that keeps giving.
