         | Agreed, Tanner is amongst the best in the world when it comes
         | to terrariums. The fact that he will often cut the glass
         | himself for making the enclosure was seriously impressive to me
         | when I first started watching.

       | > A closed terrarium is a closed ecosystem just on a much smaller
       | scale [than earth]. The supply of carbon dioxide in the terrarium
       | air is very small because of the limited volume of air.
       | Therefore, unless the terrarium contains animals to provide
       | carbon dioxide or microbes break down large amounts of organic
       | matter in the soil and release carbon dioxide, the plants in a
       | sealed terrarium cannot gain significant dry weight. They would
       | basically refix the same carbon dioxide over and over. The carbon
       | dioxide the plants release during cellular respiration would be
       | refixed via photosynthesis, then respired, refixed, respired,
       | refixed, etc.
       | 
       | > Most terrariums are not completely sealed so carbon dioxide can
       | enter and plants can gain dry matter via photosynthesis. The
       | inventor of the terrarium, Nathaniel Bagshaw Ward (1791-1868),
       | supposedly had a "sealed terrarium" that survived four years but
       | it is questionable if it was completely sealed because of the
       | substantial plant growth he observed.

       | Side-note: it's not often that a webpage from 1999 is the first
       | search result when googling (I searched "terrariums where does
       | the c02 come from" on DuckDuckGo).

       | OK, it's a century-old fad... I understand there COULD be an
       | issue if someone jumps in because of ~aesthetic~ only to grow
       | bored and toss their terrariums. But so what if someone discovers
       | terrariums "as a fad"? Or if then they build a social following
       | around it? They either actually enjoy it, which is great, or
       | they're so committed to a performative image that it's lucky they
       | latched onto plants in jars and not something more intense. Just
       | a weird angle imo that doesn't deserve the few sentences it takes
       | to address lol, just jump straight into the interesting stuff

         | conflict with patterns that a lot of experts and would-be
         | experts really treasure--for example the idea that there's a
         | qualitatively better way to develop one's identity and
         | interests. And the "it's a fad" perspective carries a lot of
         | stodgy but kinda relevant baggage for people like them-us.
         | 
         | That aspect of stepping into an exciting new role as part of a
         | performance of what one sees in their feed, may be only part of
         | a sort of ephemeral-passion-first route leading to more and
         | deeper passion later, but a lot of times it is also a feed-
         | candy-first thing in which the entire cultural or historical
         | narrative of that hobby is effectively told to shove off.
         | Carrying that narrative forward are a lot of people who have
         | deep, relevant experience but who are effectively voiceless in
         | comparison to feed-churn content creators.
         | 
         | Plus there are a lot of deeply-qualified experts who look out
         | onto that feed-world every day and wish for even just a few
         | seconds of recognition for their own difficult-to-relate depth
         | of interest, and instead they see shallow content, the
         | /r/stupidfood of whatever it is they're good at.
