My review of this book is necissarily colored by my expectations going into it. I am an aspiring terrarium builder who has tried and failed to build terrariums in the past from low budget, locally sourced materials. As such, I went into this book looking for two principle things. First, I wanted to gain deeper technical knowledge of how terrariums work and fail, so that I can figure out why my terrariums died in the past and how to stop it from happening again. Second, I was interested in recommendations on places to buy, not expensive, but maybe nicer quality materials for constructing my terrariums in the future. Noteably, as I have access to social media like Instagram and YouTube (and hell, even just Google), and I fancy myself to have a rather strong aesthetic sense, I was not really looking for a design guide - I would be fine figuring that out myself.
You may be able to see where this review is going now. Maybe it's not fair of me to judge this book based on what I specifically wanted, but this book did fail to deliver on my hopes, because it is mostly pictures of design ideas with limited technical information and resources to provide. If you want to see pictures of different kinds of terrarium builds you can try, this is fine for you - but then again, why do that when you could subscribe to a channel like SerpaDesign or TheGreenMachine? This also isn't to say that the things I was looking for were wholly missing from this book. I did learn a few things about how to buy terrarium appropriate gravel and activated charcoal, and a bit on how to diagnose failing terrariums and how to maintain moisture levels. But this information is mixed irregularly into a lot of fluffy aesthetic prose, and also isn't particularly technical (the author is talking about a lot of different container types in this book, but when talking about moisture and condensation, she rarely specifies which container she's speaking in context to, even though that matters significantly).
Ultimately, I'm walking away from this book feeling like I learned a very small number of useful facts for terrarium building, and like I'm ultimately going to have to figure out my terrarium woes the same way I had to the first time - by trial and error.
