Basics

The jar

A sealed jar waters itself: plants breathe water out, it beads on the glass and runs back down.

• Sealed: humid inside, rarely needs water. Suits ferns, moss and tropical plants.
• Open: dries out, needs watering. Suits succulents and anything that rots in damp air.
• Bright but indirect light. Direct sun through glass cooks a jar.
• Misty glass in the morning is healthy. Fogged all day means too wet: open it a while.
