nothing if you were to insulate it and your heater was able to keep up with the temperature swings. other wise most plants would die from cold. especially when the plants you put in there are exotic zone 7 and above. so minimum temp of 55 or 60
If you placed a terrarium on top of black ice, the cold temperature of the ice would likely lower the internal temperature of the terrarium, potentially harming the plants and microorganisms inside. The ice's slick surface could also make it unstable, risking the terrarium's tipping or sliding off. Additionally, if the terrarium is sealed, condensation might form inside, but if the conditions are too cold, the plants could suffer from frost damage. Overall, the viability of the terrarium's ecosystem would be compromised.
I am bringing the desert indoors by building a terrarium! My pet tarantula will love his new terrarium!
it would sharpen
It would lose salt into the water.
it would burst
they would have to adapt to the cold
It would float.
increase
I am guessing that it will either foam up or blow up not blow up like HUGE but you know, a small one
If plants and trees were placed in a de-oxygenated environment, the plant would die!
It dies.
Nothing. The onion will get wet.
