21 cited sources, every one from the RHS, a university extension service or a national botanic authority. No blogs, no retailer guides. Three complete indoor plant builds, drawn and dimensioned: a closed glass terrarium, a three-pot succulent group, and a young staghorn fern mounted on cork. Most plant-display content shows you a finished picture and leaves you to reverse-engineer it. This does the opposite. Every project gives you the container size, the substrate volume in litres, the starter pot size of each plant, the clearance to leave, a top-view and side-view plan, and a numbered assembly sequence with a checkpoint at the end of each stage — so you can order the parts before you begin instead of discovering halfway through that the jar opening is too narrow for your hand. Original specifications, not a reprinted seller's guide The dimensions, volumes, quantities, layouts, assembly sequences, checklists and project names are original written specifications, and the guide states that the written specifications and diagrams govern the build. The plant-care principles underneath them are cited, page by page, to published horticulture. The designs have not been physically built or growth-tested, and the guide says so rather than implying otherwise — no appearance, maintenance interval or lifespan is promised. Nobody else in this category tells you which half is which. The myth this guide will not repeat A layer of gravel or clay balls at the bottom "for drainage" is the single most repeated piece of terrarium advice, and it is wrong in both directions. A sealed jar has no outlet, so nothing drains anywhere. In a pot that does have a hole, a coarse bottom layer raises the saturated zone rather than lowering it. This guide keeps a thin clay band in the glass build because it looks right, says so in those words, and replaces the myth with a moisture routine based on inspection. It also gives a substrate-only alternative for anyone who would rather not have the band at all. The three projects Canopy in Glass — a closed cylinder about 30 cm across and 30–32 cm high, planted with a white-veined and a red-veined Fittonia and a clump of Selaginella kraussiana, with one dark stone as the anchor. Twelve numbered steps from empty jar to settled lid, including what to do when water has pooled. Stone & Window — Haworthiopsis attenuata, Haworthia cooperi and Haworthia retusa in three separate terracotta pots on one charcoal tray. One material, three silhouettes, and separate root zones so any plant can be lifted out, watered or replaced without dismantling the other two. Fern on Cork — a young Platycerium bifurcatum tied to a 25 × 35 cm cork slab on a tabletop stand. No wall fixing, no dividing a mature fern, and the mount lifts off for soaking. What is in the 46 pages A component atlas per project — every part named and pictured before you are asked to buy it. Shopping lists with specifications, not just names: species, starter pot sizes, jar and tray dimensions, substrate volumes, mesh diameter, stone size, and how much of each to buy. A dimensioned plan for each build, in top view and section, with layer depths given front and rear. 28 numbered assembly steps across the three projects, each stage ending in a checkpoint you can actually verify. Three troubleshooting pages, arranged by what you can see rather than by what is wrong — wrinkled leaves, a stretching rosette, a mount that slips, glass that will not clear. A care-at-a-glance table that puts the three routines side by side, because the container decides where water can go: a sealed jar retains it, a pot sheds it through a hole, a mount exposes its root pad to air. A first-30-days page of inspection prompts — deliberately not a watering timetable. A substitutions page that states, for every swap, what must stay true. Three printables: a build record, an observation log and a set of quick-care cards. What it does not do No brand of container, substrate, tool or lamp is named anywhere in it. It does not tell you to mist on Sundays or water on a schedule, because the guide's position is that inspection belongs on a calendar and watering does not. It does not promise an appearance, a maintenance interval or a lifespan. And it does not pretend the pictures are evidence. What you get PDF — 46 pages, US Letter, prints cleanly at home. There is deliberately no EPUB: the value here is full-page plates and dimensioned plans, and a reflowable format destroys both. 9 full-page plates — digitally rendered illustrations of the intended designs, not photographs of built displays. 3 dimensioned plans, 3 printable worksheets, and 21 numbered sources with a note at the foot of every page that uses one. Instant download. Nothing ships.
