Bolsk Glass Large Hanging Terrarium

The best large hanging terrarium combines an open top for ventilation with glass thick enough to survive accidental contact. The Bolsk sphere measures 10.5 inches in diameter — generous room for three to five small succulents or a single dramatic tillandsia xerographica. Our production manager, Cal, tested every prototype by swinging it gently into a doorframe. The ones that survived became the production run.

Screw a ceiling hook rated for at least fifteen pounds into a joist or use a toggle bolt in drywall. Thread the included chain through the hook and adjust length until the sphere hangs at eye level or slightly above. Our installer Nadia prefers toggle bolts because she trusts mechanical fasteners more than her ability to locate joists, which is a reasonable position given that she once drilled into a water pipe.

Both thrive in the Bolsk. Succulents want a gravel-and-soil base inside the sphere; tillandsia need only a loose nest of dried sphagnum moss. The open top prevents the moisture buildup that kills desert species. Our plant buyer, Connie, keeps a mixed arrangement — two echeveria surrounded by three ionantha — and the combination has survived fourteen months without a single casualty.

The sphere is 10.5 inches in diameter with a top opening roughly four inches across. The tube variant measures 14 inches wide, 7.3 inches long, and 7.5 inches tall. Our shipping coordinator Phil describes the sphere box as roughly the size of a basketball wrapped in bubble padding, which is accurate enough for anyone planning shelf space.

Four to six hours of bright indirect light daily. Hang the Bolsk within four feet of an east-facing or north-facing window for consistent exposure without scorching risk. Our office manager, Ruth, suspended hers directly beneath a skylight and rotates the chain a quarter turn weekly so every side receives equal illumination — a habit she describes as necessary and everyone else describes as obsessive.

It ships in three configurations: the hanging sphere, the hanging tube, and a table sphere that sits flat without a chain. Each is sold individually so you can mix shapes in the same room. Our visual merchandiser, Glenn, alternates sphere-tube-sphere across a kitchen window and claims the rhythm matters, though he also arranges his lunch by color.

Use a narrow-spout watering can or a spray bottle aimed through the top opening. For succulents, pour a thin stream along the gravel edge every ten to fourteen days. For tillandsia, mist the leaves three times weekly and soak monthly by unhooking the arrangement. Our warehouse lead, Troy, uses a turkey baster for precision, which looks ridiculous and works perfectly.

The Bolsk launched in 2016 during a stretch at Chive where products were named after words that simply sounded forceful, no vetting required. Best anyone can reconstruct, the name came off a menu at a German restaurant, possibly attached to a sausage. Nobody has confirmed the etymology, and at this point nobody is going to.
