How To Care For Your Terrarium
Closed terrariums recycle their own moisture so you should see a light condensation (As shown in image 1) in the morning that disappears by evening. This flow state is what keeps your terrarium the healthiest and happiest
If there’s no condensation - Its tooo dry (As shown in image 2). Add a few tablespoons of water each day until it starts to appear.
If there’s a lot of condensation: That means there’s too much water (As shown in image 3). You can leave the lid off for a day to let it dry out a bit, then gently wipe the inside with a paper towel if needed.
Water
NOTE: Some terrariums glass have a small layer of anti-fog on them and wiping could remove this layer.

Most terrariums like bright indirect light (As shown in image 4), a spot near a window is perfect. Keep in mind that if the light is too low plants get leggy or fade color. Do not expose your terrarium to direct sunlight (As shown in image 5) it can overheat and burn your terrariums. My rule of thumb is; Terrariums should see the sky, not the sun. Another option would be giving it artificial light for 8-10hrs a day depending on the strength of your light

Temperature

Room temperature is perfect, no more than 75°F and no less then 65°F. (But i do notice them grow faster in a bit warmer temp) Anything under 65°F slows the growth and can cause plants to sulk, drop leaves, or stop growing. Anything above 75°F will cause plants to overheat, mold or overgrow algae, suffocating everything inside the glass. Keep away from heaters, AC vents, and cold drafts. Neutral stability if you know what I mean
Maintenance
Remove dead or yellowing leaves immediately as they tend to grow bad mold. You could also open briefly every few weeks to refreshen things up (this is optional).
If you see gray mold, remove affected leaves, leave it open in direct sun light for NO MORE THAN ONE HOUR. Close terrarium and check regularly, repeat process as many times needed.
Give your terrarium a little shape-up as they grow! In whatever design your heart desires, this is YOUR world after all so make your dream garden.
Personal Tips
If you see GREEN or WHITE mold don’t worry, that’s not “bad” mold. Green is a symptom of too much light. White is just mold eating dead matter. They don’t cause any harm, unless it starts blocking out light to your plants
If your plant starts leaning too much towards one side of the glass, try rotating it. If the light is low they tend to be greedy and reach out for the light
If your terrarium has very light or heavy condensation but the plants look healthy, don’t panic. There’s a safe range for condensation, and you’re probably still within it.
