So, you’ve got yourself a closed terrarium, but wondering what’s the best water to keep it hydrated? These little ecosystems are pretty much self-sufficient, but there’s one key thing you’ve got to get right: watering. Too much, and you’ve got a swamp on your hands. Too little, and your plants might struggle. So, let’s dive into see how to keep your terrarium perfectly hydrated!

Do Closed Terrariums Even Need Watering?
Yep! Even though they recycle moisture, they still lose a little over time. The trick is knowing when and how much to add. The good news? You won’t need to water often, just a little now and then.
Signs Your Terrarium Needs Water:
Dry soil – If the soil looks completely dry, it’s time for a drink.
Limp or wilting plants – Your greenery should look perky, not sad or lacking colour.
No condensation – A little mist on the glass in the morning is a good sign.

How to Water Your Closed Terrarium (Without Overdoing It)
A heavy-handed watering can ruin the balance inside your terrarium. Instead, go for a gentle misting or precision watering.
Best Watering Methods:
Misting: A few mists with a spray bottle add moisture without flooding.
Dropper or syringe: Perfect for targeting thirsty roots.
Teaspoon: A small amount of water near the base of plants is better than drowning the whole thing.
How Often Should You Water?
Closed terrariums only need water about every couple of months, depending on the environment. Keep an eye on the moisture level and adjust as needed. Less is always more in this environment!
What If You Overwater?
Oops—too much water? Don’t panic! Here’s what to do:
Leave the lid slightly open for a few hours to let moisture escape.
Blot excess water with a paper towel if you notice puddles.
If mould appears, remove affected plants and trim any rotting leaves.

Quick Watering Checklist
✔ Check soil moisture - dry soil means it’s time to water.
✔ Look for plant wilting - droopy leaves need hydration.
✔ Watch condensation levels - some misting is good; none may mean dry air.
✔ Use misting, a dropper, or a teaspoon - no heavy pouring!
✔ If overwatered - ventilate or blot excess moisture.
✔ Less is more - water only when needed!
Follow these steps, and your terrarium will stay lush and healthy! 🌿
Final Tip: Trust Your Terrarium
Your terrarium is smarter than you think! If you see condensation in the morning and dry glass by evening, it’s doing its job. A little patience goes a long way in keeping your mini ecosystem thriving.
