Depending on where the Terrarium is kept, it may develop either too much or too little moisture. Follow our advice to restore the ideal conditions of your miniature landscape.
The glass is thoroughly wet, droplets are running down the sides. What should I do?
If droplets form on the glass of your Terrarium, there is probably too much moisture inside. To balance the moisture, proceed as follows: leave the Terrarium open for 12 hours, preferably at night. Close it again in the morning. Check the glass after a few hours. If droplets form or the inner surface is fogged up, repeat the operation.
If, on the other hand, a slight veil of moisture forms near the cap, but the rest of the jar looks dry, you have restored the optimal conditions for the ecosystem of your Terrarium.
The inner surface of your Terrarium looks slightly moist and seems to dry slowly (from top to bottom). Is this normal?
This is a good sign: it means that the ecosystem inside the Terrarium has reached a balance and the ideal conditions for its growth have developed.
The inner surface of the Terrarium glass is completely dry, and the inside is perfectly visible. Should I water the plants?
When the Terrarium glass looks dry and the inside is visible without any fogging glazing, it means that there is not enough moisture and the plants inside may be affected.
To restore the correct moisture balance, spray the inside with distilled water or mineral water (softer than tap water) every ten days.
Can I dry the condensation that forms inside the jar?
A fine layer of condensation on the inside of the glass is vital for the Terrarium ecosystem: unless actual droplets form and there is clear stagnation of water.
Condensation is a sign of the life cycle produced in the Terrarium: water vapour deposits on the glass, runs over the leaves or the soil and keeps the environment moist, allowing the Terrarium to live.
