Notes on Plant Selection
Open Terrariums Open Terrariums comes up sooner than most beginners expect. The first time you actually have to deal with it is often a week or two...
Terrariums is one of those hobbies where the gap between beginners and experts is mostly time, not talent. Almost anyone who keeps planting for two or three seasons becomes competent. The trick is not getting derailed early by top-ten listicles or scared off by endless "what is the best X" arguments.
This site is a small attempt to flatten the early learning curve. The first thing worth getting right is humidity. After that, working on lighting for a few weeks pays off more than buying anything new. The pages here go through both, with occasional digressions.
Closed Terrariums
Closed Terrariums is the area of terrariums where habits form fastest, both good and bad. After three or four sessions of doing closed terrariums a particular way, your hands stop thinking about it and the pattern becomes automatic. Re-learning a bad habit later takes weeks. It is worth being a bit careful at the start, even if it slows you down.
The way to be careful is not to be perfect; it is to be consistent. Pick one approach to closed terrariums and stick with it for ten sessions before changing anything. If something is not working after ten sessions, then experiment. Switching after every session is the surest way to never get good at any approach.
Plant Selection
Plant Selection is one of the small areas of terrariums where written advice consistently underplays how much variation there is between people. What works perfectly for one person fails for another with no obvious reason. This is not a sign of mystery or talent — it is just that plant selection interacts with personal habits, environment, and equipment in ways that no general guide can fully cover.
The practical implication: take any specific recipe for plant selection as a starting point, not a destination. Try it for a few sessions, notice what is and is not working, and adjust deliberately. Within a month or two you will have your own version, which will be better than any generic advice for your situation.
Open Terrariums
A useful exercise: write down everything you currently do for open terrariums from memory, without looking anything up. Then do the same thing tomorrow without referring to today's notes. The differences between the two lists tell you which parts of your open terrariums routine are reflexive and which are still being figured out. The reflexive parts are where habits have set; the inconsistent parts are where deliberate attention will pay off.
Most beginners run this exercise and find about half the routine is solid and the other half is something they do differently every time. That is normal — and a clear map of where to focus next. Approach open terrariums with that map in mind for a few weeks and the inconsistent half will steady up.
Drainage Layers
A useful exercise: write down everything you currently do for drainage layers from memory, without looking anything up. Then do the same thing tomorrow without referring to today's notes. The differences between the two lists tell you which parts of your drainage layers routine are reflexive and which are still being figured out. The reflexive parts are where habits have set; the inconsistent parts are where deliberate attention will pay off.

None of this is meant as the last word. terrariums is a hobby in which experience reliably outperforms instruction, and the only way to develop that experience is to keep pruning. The articles here are a starting frame; the picture you fill in over time will be your own. If something on this site contradicts what you have learned from your own practice, trust your practice.
