You need to make the most important option of the whole process before you start building or even planning your terrarium .

It will impact the aesthetics and the longevity of the system . It ’s the difference between regular maintenance and no upkeep at all ! .
We touched on it in the last chapter ( Can a terrarium be ego get ? ) , but it bears repeating . A sealed terrarium has no substitution of thing with the outside . It has two crucial corollary :

Of course , like everything in life , it ’s not quite black and white . Since terrariums can be made in slew of container , there are varying degrees of “ sealedness ” . A fix jarful with the lid screwed on tight is about as seal as you could get . It ’s intemperate to completely varnish those liberal terrariums made from fish storage tank , and you probably would n’t need to .
Theoretically , if you were originative enough ( and had silicone ) , you could seal off anything . However , some containers are proficient off not being seal at all or completely .
It ’s also deserving mentioning that there ’s a number of an in - between method . It ’s plebeian to make a sealed terrarium that is only opened sometimes to water , clear , and generally freshen thing up .
And , actually , that method is a great compromise . It makes making a sealed terrarium a lot easier and less complicated , but it usually needs a destiny less attention than an open terrarium anyway .
This third category does n’t really qualify as either seal or unsealed . If it ’s ever open , even once , you break the sealskin ( literally ) and it ’s no longer truly self - keep up . As far as science is touch on , at least . You would n’t be able to apply that terrarium as data point because it was compromise .
Of course , that ’s a moderately pretentious viewpoint . Not many of the hoi polloi reading this plan to utilise their jarful of bugs and plants as a research power point . Ultimately , you should use whichever scheme fetch you the most satisfaction .
That last one might not even be a con game . perhaps I ’m the only one who thinks that way .
As the creator , it ’s up to you , but for the purposes of this site , most of the lessons and guide will be about how to make a sealed terrarium . After all , you ’re on SelfSustainingEcosystem . com ! .
That view can be considered a “ confine ” view on terrarium . With a few small changes , everything we spill about will also work for unsealed ( or sometimes uncertain ) terrarium , so it ’s all useful information .
