How To Care For Your Terrarium
Closed terrariums recycle their own moisture. You should see light condensation (As shown in image 3) in the morning that disappears by evening.
If there’s no condensation at all: Its tooo dry (As shown in image 1). Add a few tablespoons of water each day until it starts to appear.
If it’s super foggy or dripping: That means there’s too much water (As shown in image 2). You can leave the lid off for a few days to let it dry out a bit, and gently wipe the inside with a paper towel if needed.

Most terrariums like bright, indirect light; a spot near a window is great, just not where harsh sun hits the glass. I repeat Do not expose your terrarium to direct sunlight (As shown in image 3) - it can overheat and burn your beautiful terrariums.. If the light is too low, plants get leggy or fade. My rule of thumb for this is making sure where ever you place your terrarium it can SEE the sky but never get touched by the sun. (As shown in image 4). You could also use artificial light, but you would have to leave it on for 10 hrs

Room temperature is perfect, no more than 75°F and no less then 65°F. 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
Temperature
Give your terrarium a little shape-up as they grow however you desire, this is YOUR world to mold. Remove dead or yellowing leaves and open briefly every few weeks to refresh things. If you see mold, remove affected leaves, leave it open in direct sun light for no more than one hour
Tip: You can also rotate your terrarium if your plant start leaning too much on one side
Maintenance
If you see GREEN or WHITE mold don’t worry, that’s a symptom of too much light, they don’t cause any harm, unless it starts blocking out light.
