Terrarium kits: choose the right type and check what is missing

Compare the growing method, exact contents, and work left to you before buying a starter or DIY kit.

By Terrarium GuideSources & editorial method

The short answer

Choose a terrarium kit for the plants and care you want to provide. For a closed humid garden, look for an accessible covered vessel, identified compatible plants, suitable root medium, and usable planting and care instructions. “Starter,” “complete,” and a finished product photo do not tell you which of those are in the selected option.

A refill can make sense when you already have glass and tools. For drying succulents, plan an open arrangement with a real water outlet; for epiphytic air plants, keep the plant removable with airflow and drying space. Seeds and preserved decorations serve different projects from an established living foliage garden.

Evidence[3][4][5][6][9][13]

Start with the project, not the number of pieces

Kit types and the job each one actually leaves you
Your project	Useful kit specification	Check before choosing
Closed humid foliage garden	Covered clear vessel, compatible living plants, appropriate root medium, planting and ongoing care guidance.	Actual plant identities, usable space and opening. A fully planted photo may show an example rather than every included item.
Refill for glass you already own	Specified quantities of medium and any chosen base materials; plants and moss only if selected.	Glass is often excluded. Match quantities to the inside footprint and planned root depth, not just “small” or “large.”
Plant-only assortment	Named plants, quantity and arrival form, with a substitution policy.	You still need the vessel, root medium or support, tools and growing position. A mixed pack is not proof of compatibility.
Open drying succulent display	An open display with a draining planting container, appropriate mix and identified plants.	Look for a real outlet or a removable draining pot. Gravel in a solid glass base does not provide an outlet.
Epiphytic air-plant display	An identified air plant and accessible, open support or vessel.	Remove the plant for watering and drying. Sand and shells are decorative; a soil bed and a sealed lid are not the intended growing method.
Seed-growing activity	Named seeds, growing containers or medium, instructions and the relevant age/supervision guidance.	Expect sowing and a growing stage, rather than an instant planted foliage garden. Read the actual manual for the experiment.
Preserved or artificial display	Clear labeling of what is preserved, dried or artificial.	Choose it for decoration. If you want living growth, do not buy preserved moss or faux plants as substitutes for live plants.

Worked check: a no-glass ingredients kit

Using the Botanical Boys small no-glass listing, the result is “ask first” for a buyer who wants to use an existing vessel. The public description confirms some contents but does not establish the plant identities, actual sizes or material quantities needed to check that vessel. This is a completed listing review, not a tested planting recipe.

Fill the same confirmed / needed / ask fields in your worksheet
Field	What the public listing establishes	Record and next action
Confirmed in the box	Tools, clay pellets, sphagnum, substrate, decorative materials and plants are listed.	Record those categories, without inventing plant names, amounts or suitability.
Needed separately	The title and description exclude the glass vessel.	Use a measured suitable vessel you own, or include one in the shopping list and cost.
Plant identity and fit	Plants are listed without the botanical names or actual sale dimensions needed for this check.	Ask for current identities, rooted state, rootball/canopy sizes and substitutions. Compare the reply with your intended care and vessel.
Medium quantity and vessel range	The description names materials but does not provide the prepared amounts and usable planting dimensions needed here.	Ask for the ingredients, added fertilizer, prepared quantity and intended planting area. Keep fit and top-up costs open until answered.
Instructions and receiving	The page describes build/care guides reached through a QR code inside the box.	Ask to read the relevant instructions before buying, and confirm dispatch, receiving and issue-reporting arrangements for your destination.
Decision	A no-glass ingredients format is confirmed; fitness for this buyer’s vessel is not.	ASK FIRST. Send the questions below; add confirmed extras and quotes to the worksheet. If a necessary answer remains unavailable, choose another offer or separate supplies.

Hello, I am considering [product URL and exact option].
My plan is [closed humid foliage / open drying display / air-plant support / named specialist].
I already own [vessel and tools, or none].
If I already have a vessel, its dimensions are [narrowest opening width], [usable internal floor width] and [internal height], with units.
My growing position and light are [describe].

Before I order, could you confirm:
1. The botanical names, current canopy/rootball sizes and rooted state of the supplied plants, and any substitutions? If moss is supplied, is it living, dried or preserved?
2. The growing-medium ingredients, added fertilizer and prepared quantity, plus the container size/usable planting area this pack is intended for?
3. If glass is included, its narrowest opening, usable internal floor dimensions and internal height (with units), and whether the cover is removable?
4. Which tools, separator, supports or other required parts are included in this exact option?
5. Can I read the planting and care instructions before purchase?
6. Dispatch timing to [destination], whether live plants arrive separately, and the damage/missing-item reporting policy?

I will compare your answers with the plants' needs and my container before ordering. Thank you.

Evidence[2][4]

Audit the selected option before checkout

Write each item as included, already owned, or still to buy. An unspecified detail is a question for the seller, not an assumed extra.

Glass, cover, and working openingConfirm that the container is included, its inside dimensions and opening, and whether the lid is part of this option. Can the actual rootball or support enter and later come out? Outer width alone does not answer that.
Evidence[3][9][10]
Live contents and substitutionsGet plant names, quantity, sales size and arrival form. Separate live moss from dried base fibers or preserved decoration. Ask which plants may change and whether you can decline a substitute before dispatch.
Evidence[9][10][11][8]
Root medium, amounts, and any separatorFind ingredients, added feed and the volume supplied. For a layered humid plan, establish what keeps fine medium from mixing into the coarse collection space. Do not assume that every bag is a root medium or that all of it must go into the vessel.
Evidence[4][9][11]
A real growing positionCheck the plants against the light where the display will live. An LED ornament or illuminated lid may only light the scene for viewing. For example, Tropical Glass explicitly describes the Barcelona LED lid as decorative, not a grow light; its batteries are excluded.
Evidence[3][10]
Tools and controlled wateringCompare tool reach and the size of the opening with implements you already own. A spoon, brush and narrow-spout container may do the work. Check whether tools are standard, optional or absent rather than paying twice for the same function.
Evidence[4][9][10]
Instructions that continue after assemblyLook for watering checks, placement, ventilation or drying, growth management, and a route to ask about the actual plants. Instructions that only show decorative layers leave the ongoing task unfinished.
Evidence[3][5][10][11]

Check the proposed base and water route Collection space and a real drainage outlet perform different jobs.
Assess the growing light separately Check leaf-level coverage and placement before buying a lamp add-on.

Real listings: compare what the name leaves out

These examples illustrate different buying decisions. They are not ordered by quality or value, and a listed plant pack is not our endorsement of every plant or substitution. Read the current variant and delivery terms on the supplier’s own page; the examples do not promise service to your address.

Already own glass? Tropical Glass Basic Starter Kit — UK

The base listing specifies soil, clay pebbles, activated charcoal, a cork tamper and a guide. Glass is explicitly excluded; plants, moss and tool sets depend on the selected options. This is a useful comparison for a refill, but not a complete purchase for someone starting with no vessel. Ask about quantities and the plant identities in the chosen size.

Check Basic Terrarium Starter Kit contents and options

Need glass too? Tropical Glass Barcelona — UK

This listing includes a covered glass container, live plants, moss, growing materials, decorations and a guide. Tool sets and the LED lid are optional. The seller says the LED is aesthetic rather than a grow light and that plants can be substituted. Confirm the current plant list and care needs before accepting an assortment; included glass does not resolve light or long-term growing space.

Check Barcelona kit contents, optional tools and decorative LED lid

Compare the arrival form: Flower & Twig Tropical Jar XL — Australia

The listing specifies a lidded jar, seven assorted plug plants, live moss, separate growing and decorative materials, two wooden assembly tools, and assembly/care guidelines. The important difference is the assortment of plugs: ask for the actual plant selection and how each is prepared, rather than assuming seven mature potted plants. Check the seller’s current destination limits and who will care for the live contents before a gift is opened.

Check Tropical Jar XL contents, plugs and delivery area

Want a removable air-plant display? Air Plant Shop Teardrop Beach — US

The supplier describes a glass teardrop, a living air plant, white sand, decorative stones and sea-life accents. This buys a display arrangement rather than a humid soil-garden refill. Check the actual plant and opening, and make sure it can be removed without pulling it through decorations. Keep a separate watering and complete drying route; decorative sand is not the plant’s root medium.

Want to sow seeds? Thames & Kosmos Light-Up Terrarium

Wow in the World: Light-Up Terrarium is a seed-growing science activity. The manufacturer describes cress seeds, growing containers, faux plants, glowing decorations and UV LED string lights. Choose it for that experiment and follow its age and supervision instructions. It does not provide established foliage plants, and its glow effect is not evidence that the growing-light needs of replacement plants are met.

Check quantities against usable space

Ask for liters or another clear volume for the root medium, and for the intended planting footprint and depth. “One bag” and the vessel’s total capacity include no assurance that roots have enough room after base materials and decorations are added.

For a rectangular planting footprint, a rough geometric estimate is inside length × inside width × planned medium depth in centimeters, divided by 1,000, to obtain liters. A 20 × 10 cm footprint with 4 cm of medium is 0.8 L before rootballs and hardscape displace it. This illustrates volume only: 4 cm is not a recommended depth for every plant, and a curved or tapered jar needs a different estimate.

Leave room above the planting for leaves, growth, a fitted lid and access. Do not pour in every supplied bag to make the package empty. If the roots, growing medium and access cannot fit together, choose a different vessel, fewer suitable plants, or separate components before buying.

Evidence[3][4]

Allow for the space the planting will use Check the container shape, rootballs, cover, and future care.
Choose root medium for the planting Keep ingredient and root requirements with your quantity estimate.

Try your own tools before buying a tool add-on

Use an empty vessel to test reach, controlled pouring and the route in and out. A short handle may suit a wide opening; a deep narrow bottle can require longer implements.

Empty wide-mouth glass jar and separate lid beside a bowl of dark medium, a narrow-spout jug, teaspoon, long tweezers and small brush. — Check the spoon or tweezers can reach the planting area, the spout lets you control water, and the lid remains usable. These are generic examples of functions you may already own, not the contents or quantities of any kit above.

Evidence[4]

Buy the bundle, fill a gap, or choose the parts?

Buy the bundle

Useful when it removes real preparation work

Check: You need the vessel and materials, the actual plants fit the same care method, and quantities and instructions are clear.
Action: Compare the delivered total plus genuinely missing essentials with equivalent separate parts. Value the matched preparation and support you will use; ignore the decorative piece count.
Stop or reassess: A key plant, medium, growing position or access route remains unresolved. Ask before paying rather than treating “complete” as an answer.

Evidence[9][10][3]

Buy only a refill or missing pieces

Useful when the glass and tools already work

Check: Your existing vessel is clean, intact and accessible, with enough usable growing space.
Action: Order the necessary medium, identified plants or support in amounts that fit. Skip duplicated tools and decorations you will not use.
Stop or reassess: You would be forcing the wrong growing method into a favorite jar. Change the vessel or planting instead.

Evidence[4][5][9]

Choose components separately

Useful for specific roots, plants or maintenance needs

Check: You need a draining inner pot, a removable mount, a particular plant or a specialist root medium.
Action: Build one coherent list for that method. For a flytrap, confirm its water, nutrient-poor medium, light and seasonal plan rather than adapting a generic fertilized foliage pack.
Stop or reassess: The combined order is still an assortment without a shared care method. Keep incompatible plants in separate arrangements.
