Our Picks at a Glance
How To Choose The Best Jars For Terrariums
A terrarium jar creates its own microclimate, not just a container. The wrong jar can drown plants in moisture or dry them out in a day. Here is what to look at before you buy.
Glass Thickness and Material
Borosilicate glass is the top choice because it resists heat and handles temperature shifts without cracking. Thicker glass also adds weight, which keeps the jar stable on a desk or shelf and reduces the chance of toppling. If the jar feels light in the description, check the weight — a 1.5-pound cloche is far less fragile than a thin 0.35-pound globe.
Opening Size and Shape
A wide or slanted opening makes it easy to arrange soil layers and place plants without tearing roots. Narrow necks look elegant but require long tweezers or a spoon for setup — a detail owners of small-opening jars often mention. For closed terrariums, a cork lid or glass top that seals well is essential for maintaining the internal water cycle.
Volume and Plant Fit
A 1-liter jar (about 34 fl oz) is a good starting point for a small fern or fittonia. Larger jars, around 1.7 liters, give a Venus flytrap or jeweled orchid room to spread. For air plants and succulents, an open bowl or globe works because they prefer less humidity, while moss and tropical plants thrive in sealed containers that trap moisture.

In‑Depth Reviews
1. NCYP Glass Cloche Dome with Air Hole and Base
Our pick — over 4.5★ from 350+ verified ratings; the strongest balance of quality and price.
A humidity-locking cloche that buyers call perfect for jeweled orchids and Venus flytraps.
This crowd favorite uses borosilicate glass thick enough to survive a dog knocking it over (buyers confirm) and clear enough to show every terrarium layer. It holds 1.7 liters, which gives a Venus flytrap or a jeweled orchid room to spread without feeling cramped. The two-piece design means the dome lifts off cleanly for watering or feeding insects, and the small air hole on top keeps airflow moving so you do not get mold in a sealed space.
The base itself is glass, which eliminates the water-damage risk you get with wooden stands. A few owners note that condensation can drip from the top onto the surface below — easily solved by sitting it on a small dish. The hemispherical bowl with a flat base sits solidly on a bookshelf or desk and draws the eye immediately. At 1.5 pounds, it feels substantial without being a burden to lift.
Buyers sum it up well: “This container works wonderful as a terrarium for my jeweled orchid.” The moisture retention gets consistent praise — one owner said their plants “look less sad during winter.” Hundreds of owners confirm this is the jar most people reach for a reliable, beautiful home for humidity-loving plants.
The Real Strength
- Thick borosilicate glass — survived a dog knocking it over twice, per one owner
- Two-piece design with a glass base — no wood to warp or rot
- Top air hole gives airflow without losing humidity
The Honest Trade-Off
- Condensation drip from the top may need a small dish underneath
- 1.7-liter volume is generous but not huge — larger plants may outgrow it
Reach for this if: you grow moisture-loving plants like orchids, ferns, or carnivorous species and want a cloche that locks in humidity without feeling fragile.
Think twice if: you need a fully sealed closed ecosystem — the air hole is intentional for airflow, so it is not 100% airtight.
2. Mkono Plant Terrarium Display Glass Tabletop Succulent Air Plant Planter Globe
A tilted globe that makes air plants look like floating sculptures.
The Mkono globe is the one you buy when the jar itself is part of the decoration. That special oblique mouth — the slanted opening — gives it a modern, sculptural feel that works on a coffee table or as a wedding centerpiece. It is made from borosilicate glass, so it handles light and temperature well, and the 5.5-inch diameter is large enough for a decent-sized air plant or a small succulent arrangement. Buyers often use it with polished gravel or as a moss kit for miniature scenes.
The honest trade-off here is the glass thickness. This is a thin, delicate globe — several owners mention it feels fragile, and a few received chipped units. The size also gets mixed reactions: some find it “larger than expected,” while others say it is smaller than it looks in pictures. For the price, you are paying mostly for the design. If you need something sturdy that can survive a bump, the NCYP cloche at a similar price point offers thicker glass. But if you want an elegant, open-form display for a single air plant, this shape is tough to top.
The review pages sum it up: “My cats broke the glass globe for my air plants so I tried this as a replacement.” That single line captures the buyer reality — this is a decorative piece that rewards careful placement. When displayed on a high shelf or in a low-traffic area, it looks genuinely beautiful.
Design-first pick: The oblique opening is the selling point — it catches the eye and improve a simple air plant into an art piece. The thin glass demands gentle handling.
Best for: air plant owners who want a modern, tilted globe as a centerpiece or shelf accent.
Not ideal for: homes with active kids or pets that might knock it over — the glass is thin and breakage reports are not rare.
3. Biggun Plants Propagation Station — 2-Pack Desktop Plant Terrarium Glass Hydroponic Vases
Water-drop shaped jars with cork tops that make root propagation easy to watch.
These are not just terrariums — they are purpose-built for water propagation. The drop-like shape gives roots room to spread downward, and the clear glass makes it easy to see when the water needs changing. Each jar comes with a cork lid that has a pre-cut hole, so you can insert a cutting and let it dangle into the water without the stem falling in. The bamboo tray base adds stability and a natural look that contrasts nicely with the transparent glass. At 1.1 pounds for the pair, they are light enough to move around but solid enough to hold a small plant.
The appearance is what buyers praise most — over 40 separate mentions highlight how good these look on a window sill or desk. The glass quality gets consistent approval: “clear, durable and adequately thick,” as one owner put it. The size, however, is a point of debate. Some buyers find them perfect for small clippings, while others expected something larger. At 4.3 inches in diameter, these are genuinely compact — ideal for a single cutting or a small air plant, not for a full-grown fern.
Compared to the Mkono globe, the Biggun jars offer a more practical setup for actively propagating plants, with the cork lid being the key differentiator. Against the NCYP cloche, they trade the humidity lock for open-air root viewing. If your goal is to root cuttings and watch the roots grow, this two-pack delivers better than any single jar in the list.
Why Owners Love Them
- Cork lid with a hole holds cuttings in place without crushing stems
- Drop shape gives roots room to grow downward
- Bamboo tray base looks clean and prevents tipping
The Catch
- Small diameter (4.3 inches) — too tight for larger plants or multiple cuttings
- Open design means lower humidity; not ideal for moisture-loving plants like moss
Pick these if: you propagate a lot of pothos, philodendron, or other cuttings and want a clean, attractive way to watch roots develop.
Skip if: you need a closed terrarium for humidity-dependent plants — these are designed for open water propagation.
4. PYEF CRAFTS Terrarium Kit for Plants DIY Starter Pack — Closed Ecosystem
Everything you need for a self-sustaining ecosystem — just add the plant.
This is the only pick in the list that comes as a complete kit rather than just a jar. Inside the box you get a glass jar with a cork lid (34 fl oz / 1 liter), coconut soil, decorative stones, sphagnum moss, activated charcoal, bamboo tweezers, and a bamboo spoon — all pre-measured to fit the jar. That means no separate trips to buy substrate, no guessing how much charcoal you need. Just layer it as the instructions show, add a plant (not included), seal it, and the closed ecosystem creates its own water cycle. Once sealed, you may only need to open it every few months.
The size — 8.26 inches tall with a 4.33-inch diameter — is ideal for a beginner. Tall enough for a small fern or fittonia to grow upward, narrow enough that the moisture cycle works efficiently. A few buyers wished the substrate quantities were larger, but for a single jar, they are exactly enough. The jar itself is good-quality glass, and the bamboo tools are a nice touch that kids especially enjoy. As one owner put it, the kit “saved my red spikemoss fern’s life,” which tells you how well the closed system works for humidity-starved plants.
Compared to the NCYP cloche, this is a fully sealed environment — no air hole — so it creates true condensation-driven self-watering. Against the Biggun propagation station, it is the opposite: closed instead of open, designed for ecosystem balance rather than root viewing. For a first-time terrarium builder, this removes almost all the guesswork.
All-in-one convenience: The substrate, tools, and jar come together — nothing else to buy except the plant. The closed ecosystem then runs itself.
Best for: beginners who want a complete, ready-to-assemble closed terrarium without hunting for supplies.
Consider alternatives if: you already own substrate and tools — buying just the jar alone may be cheaper.
5. Craft And Party Slant Cut Bowl Glass Terrarium
A slant-cut glass bowl that makes a statement as a terrarium or a fish bowl.
This is the widest and most open jar on the list — 6 inches tall by 7 inches wide — and that generous opening makes it easy to work in. You can arrange soil, stones, and plants with your hands rather than needing long tweezers. The slant cut (the glass is cut at an angle on one side) gives it a contemporary look that event designers use for centerpieces. The glass is thick and sturdy, according to buyer reports, and the polished finish keeps it from looking cheap. It works equally well as a terrarium, a candy dish, or a vase for wildflowers.
The biggest concern is durability in transit. While the product itself is well-made, a fair number of buyers mention theirs arrived with cracks or chips. This seems to be a packaging issue rather than a glass defect, but it is worth noting. A few owners also report minor imperfections like streaks or bubbles in the glass — not unexpected at this price point, but something to check on arrival. For a small terrarium or a beginner fish bowl, the size and shape are excellent, and the value is hard to match.
Versus the Mkono globe, this bowl is wider and lower — better for a shallow, open landscape-style terrarium with multiple small plants. Against the PYEF CRAFTS kit, it is purely an empty vessel — you supply everything inside. The slant cut is the defining feature that buyers remember.
The Draw
- Wide 7-inch opening makes planting easy — no tools needed
- Thick, sturdy glass that feels durable once it arrives
- Versatile shape works for terrariums, fish bowls, or centerpieces
The Risk
- Some units arrive cracked or chipped — inspect immediately on delivery
- Minor glass imperfections (streaks, bubbles) reported on some units
Reach for this if: you want a wide, low bowl for a landscape-style terrarium or a fish bowl, and you value easy access to arrange plants.
Check carefully if: you need the jar for a gift or a time-sensitive event — inspect the packaging quality right away.
6. CYS EXCEL Glass Terrarium Container (H:10″ W:7″) with Wood Base & Lid
A hand-blown glass bell jar that turns moss and air plants into an art installation.
At 10 inches tall and 7 inches wide, this is the tallest jar in the selection — a proper statement piece. The hand-blown crisp glass is noticeably heavy and thick, giving it a premium feel that machine-made jars lack. It comes with a wooden base and a separate wooden cap (a small ball that sits on top). The wide 2.5-inch opening is big enough to reach into with tools or your fingers, making planting reasonable despite the height. Owners use it for everything from moss and air plants to seashell displays — one buyer simply put seashells inside and called it a conversation starter.
A recurring observation from long-term owners is that the wooden cap can get stuck due to pressure changes inside the sealed jar. One buyer who kept moss and fern in theirs for over 4 years noted that the cap eventually caused a glass crack from the pressure. The suggestion is to use a more flexible lid or to open it periodically to release pressure. The aesthetic is undeniably beautiful — “gotten so many compliments,” as one owner put it — but the cap design is a real quirk you need to manage.
Compared to the NCYP cloche, this jar is taller and more dramatic, but the cloche has a safer lid system (glass-on-glass with an air hole). Against the Craft And Party bowl, this is a completely different style — vertical and enclosed vs. wide and open. If height and visual impact are your priorities, this is the pick.
Visual centerpiece: The hand-blown glass and wooden base create a look that dominates a shelf or desk. The cap pressure issue is the one maintenance quirk to plan for.
Best for: anyone who wants a tall, elegant terrarium that doubles as a decorative statement — ideal for moss, air plants, or dry displays.
Manage carefully: the wooden cap can create internal pressure that may crack the glass — loosen it occasionally or use a flexible seal.
7. KRAFTSTORIES Glass Terrariums with Airtight Wooden Lid (Set of 3)
Three tall jars with cork-ball lids that seal tightly for a self-sustaining ecosystem.
If you want to build multiple terrariums at once — for a desk, a gift, and a windowsill — this set of three delivers. Each jar holds 1200 ml (about 40 oz) and stands 9.3 inches tall with a 3.5-inch width. That slender, tall profile is perfect for a single statement plant like a small fern or a moss column. The cork-ball lid seals well enough to create a closed ecosystem: buyers report excellent humidity retention, with condensation forming naturally inside. The small opening (3.5 inches) means you will need long tweezers or a funnel to arrange the layers, but the result is a clean, professional look.
The cork ball itself is a nice tactile detail — modern without being cold. Buyers consistently praise the appearance and quality, with one noting the design is “beautiful and modern” and the size perfect for the plants they used. Since the set is a 3-pack, the per-jar cost is very reasonable, making this a strong option if you are making terrariums for multiple people or want variety in your own space. The only real constraint is the narrow neck — plan your planting order carefully because you cannot reach in easily once the lower layers are down.
Compared to the PYEF CRAFTS kit, this set gives you three jars but no substrate — you supply your own soil, stones, and charcoal. Against the Biggun propagation station, these are taller and sealed, better for closed ecosystems than open water propagation. The cork seal is the standout feature that makes these different from any other jar in the lineup.
Three-for-one appeal: The cork ball lids create a tight seal for closed terrariums, and the tall silhouette looks modern on any desk. You will need tools for planting due to the narrow opening.
Grab this set if: you want multiple matching terrariums for a desktop display or as gifts, and you do not mind supplying your own planting materials.
Pass if: you prefer wide-mouth jars that let you plant with your hands — the 3.5-inch opening requires precision tools.
8. YIMORENCE Large Glass Terrarium House Planter with Swing Lid
A mini glass greenhouse with a swing door that keeps cats out and plants in.
This is not a jar in the traditional sense — it is a house-shaped glass terrarium with a hinged swing lid and black metal accents. The size, 9.8 inches wide by 7.9 inches tall by 5.9 inches deep, gives you a generous planting area that fits multiple succulents, a small fern, or even a Venus fly trap. The reinforced glass panels are heavy and sturdy — one owner confirmed it survived multiple moves without issue. The swing door has a small kickstand to prop it open, which is handy for adjusting plants or letting it air out.
The real-world use case that keeps coming up is pet protection. Multiple buyers mention using it specifically to keep cats away from their plants. The enclosed design works: cats cannot reach the soil or leaves, and the glass panels are thick enough to resist paws. The trade-off is that even with the door open, it holds moisture inside — one owner almost killed their succulents because the humidity was too high. That means succulents and cacti may struggle here. Moss, ferns, and moisture-loving plants are a much better match.
Versus the CYS EXCEL terrarium, this is wider and shorter — better for a landscape-style arrangement. Against the NCYP cloche, it offers a larger horizontal footprint and the unique swing-door access. The build quality is solid overall, though a few owners note that the spot welds look rough up close. Functionally, it works perfectly.
Why It Stands Out
- Swing door with kickstand gives easy access for planting and ventilation
- Reinforced glass is heavy and sturdy — survived multiple moves per owners
- House shape is playful and works well as a centerpiece or gift
Know Before You Buy
- Holds too much moisture for succulents and cacti — best for moss and ferns
- Small door opening makes it hard for large hands to arrange plants inside
Ideal for: cat owners who need to protect plants from curious paws, or anyone wanting a unique greenhouse-style display for moisture-loving plants.
Not for: succulent lovers — the enclosed design traps humidity that will harm dry-climate plants.
9. MyGift Premium Hotel Series 5 Inch Round Clear Glass Air Plant Terrariums (Set of 4)
Four half-orb bowls that work as terrariums, candy dishes, or tealight holders.
This set gives you four matching glass half-orbs, each about 3.7 inches tall and 4.7 inches in diameter. The glass is noticeably thick — buyers consistently mention the sturdy build and the pleasant weight. The slanted design gives each bowl a modern edge, making it suitable for everything from air plants to potpourri to floating candles at a wedding. One owner used them as centerpieces and called them “perfect” for that use. The glass clarity is good, though a few units have minor imperfections like streaks or air pockets — not unusual at this price for a 4-pack.
The main split among buyers is about size. Some find them “larger than expected,” while others feel they are smaller than the photos suggest. At 4.7 inches wide, they are compact — ideal for a single air plant or a small succulent, not for a full terrarium landscape. Durability in shipping is a recurring theme: several owners reported that one or two bowls arrived chipped or broken. The glass itself is thick and durable once it survives delivery, but the packaging has room for improvement. For event planners or anyone buying in bulk, that is a risk to weigh.
Compared to the KRAFTSTORIES set of three, these bowls are shorter and wider — open forms perfect for air plants, not closed ecosystems. Against the Mkono globe, they offer a similar aesthetic at a lower per-unit cost, but without the tilted opening that makes the Mkono special. If you need multiple matching mini bowls for a project or an event, this is the most cost-effective way to get them.
Budget-friendly variety: Thick glass, modern shape, and four units make this a strong choice for events or multiple small displays. Inspect on arrival — shipping damage is an occasional problem.
Pick this set if: you need several matching bowls for air plants, wedding centerpieces, or small gifts and are comfortable with the per-unit risk of shipping damage.
Choose something else if: you want a single, guaranteed-perfect terrarium jar — the 4-pack trade-off is that some units may arrive with chips.
Understanding the Specs
Glass Material — Why Borosilicate Matters
Most quality terrarium jars are made from borosilicate glass, which handles heat from sunlight or a nearby lamp without cracking. It is also more resistant to thermal shock — if you pour warm water into a cold glass jar, borosilicate will survive the temperature swing where regular glass might shatter. Thicker borosilicate glass also feels heavier and less likely to tip over with a top-heavy plant inside.
Volume and Dimensions — Matching Jar to Plant
A jar’s volume (measured in liters or fluid ounces) tells you how much soil and plant it can hold, but the dimensions matter more for how the plant fits. A tall narrow jar (like the CYS EXCEL at 10 inches) suits a plant that grows upward, while a wide bowl (like the Craft And Party at 7 inches wide) gives spreading plants room. The opening diameter matters too — wide openings let you plant with your hands, while narrow necks need long tweezers or a spoon.
Lid and Seal — Open vs. Closed Ecosystem
A cork lid or glass top that seals tightly creates a closed ecosystem where water evaporates, condenses on the glass, and drips back into the soil — you may only need to water every few months. An open jar (no lid or a loose top) lets moisture escape faster, which is better for succulents and air plants that dislike wet roots. Some jars, like the NCYP cloche, offer a middle ground with a small air hole that provides ventilation while still trapping most humidity.
Weight and Stability — Heavier Is Safer
A terrarium jar that weighs at least 1 pound is less likely to tip over when you bump the table or when the plant grows asymmetrical. Lighter jars, especially glass globes under 0.5 pounds, are more prone to being knocked over by a pet or a stray elbow. The weight also tells you about the glass thickness in many cases — a 1.5-pound cloche has noticeably thicker glass than a 0.35-pound globe of similar size.
