Petri Glass Terrarium Jar For Succulents

A wide shallow jar with a removable lid lets rosette species spread naturally while giving you direct humidity control. The Petri at 3.75 inches across provides lateral room for one or two compact echeveria, and the flat glass lid converts the open vessel to a sealed chamber during dry winter months. Our grower, Arno, stocks these specifically for customers who keep succulents on shelves near radiators where ambient moisture drops sharply by November.

Ideal. Rosette succulents grow outward, not upward — they need horizontal space more than vertical clearance. A shallow jar keeps the soil layer thin, which prevents waterlogging, and the wide opening ensures rapid evaporation after each watering cycle. Our plant consultant, Simone, recommends shallow vessels for every rosette species and reserves tall jars exclusively for trailing or columnar varieties.

Place a half-inch layer of fine gravel at the bottom, then one inch of cactus-mix soil. Position the rosette at center with its root ball pressed gently into the substrate, and fill around it until soil meets the lower leaf margin. Brush loose particles off the inner glass with a soft paintbrush. Our display coordinator, Kasper, finishes every jar with a ring of decorative sand around the rosette — purely aesthetic, but it photographs well under shop lighting.

The jar measures 3.75 inches in diameter and stands 4.75 inches tall with the lid seated. The opening spans approximately 2.5 inches across, which admits adult fingers for planting and repositioning. Our QA specialist, Elin, measures every production batch and reports consistent dimensions within a two-millimeter tolerance — tight for handblown glass and well within functional range.

Aim for roughly five hours of ambient brightness each day without direct beams. A north-facing or east-facing spot near a window provides steady illumination that avoids the magnified heat western glass produces in the afternoon. Our office manager, Frida, keeps hers on a bookshelf that catches reflected daylight from across the room — gentler than any sill position and sufficient for echeveria.

Roughly twice monthly when the plant is actively growing, tapering to once monthly in winter dormancy. Apply water from a squeeze bottle directed at the soil perimeter, avoiding the rosette crown where trapped droplets promote fungal spotting. With the lid removed, evaporation is rapid — our warehouse supervisor, Lutz, checks the soil surface with a wooden skewer and waters only when it comes out completely dry, which he calls the chopstick test.

Depends on your indoor humidity. Desert species like echeveria and sedum prefer open conditions where moisture exits the jar within hours. Tropical varieties tolerate closed or semi-closed environments where humidity lingers near the foliage. The Petri lid lets you toggle between configurations by season — remove it in humid summer, replace it during arid furnace-heated winter. Our buyer, Marek, uses the same jar all year and adjusts only the lid position.

The Petri launched in 2012, the same production cycle that split the single-glass globe from its trio mold. The naming followed the same logic as every other Chive product: it resembles the thing it is named after. A petri dish that decided to grow plants instead of mold cultures. Our original glassblower, Henrik, prototyped the wide-shallow form from a biology class memory, and the silhouette has remained unchanged since.
