BeginnerOpen jar only

What the simulation uses
- Light
- 4,000 to 30,000 lux
- The brightness it grows well in.
- Humidity
- 20 to 55 % RH
- Air moisture it is happy in; below the lower end it dries out.
- Temperature
- 10 to 28 °C
- Comfortable range; outside it growth slows.
- Dies at
- below 2 or above 33 °C
- Days beyond these temperatures kill it.
- Soil pH
- 6 to 7.5 pH
- Soil acidity it prefers.
- Grows up
- 0.25 cm/month
- How fast it gains height in good conditions.
- Spreads
- 0.25 cm/month
- How fast its edge creeps outwards.
- Copes with wet
- poor
- How well it stands soggy soil; poor means rot comes quickly.
- Copes with still air
- poor
- Sealed jars have still air; poor means grey mould finds it.
- Copes with shade
- fair
- How well it holds on in dim light.
- Copes with drying
- excellent
- How well it survives the jar drying out.
- Water use
- 0.015 ml/cm²/day
- Water drawn up from its roots per cm² of leaves in room air; a sealed jar cuts this to a fraction and returns it down the glass.
- Leaf drop
- 0.8 %/month
- Share of its leaves it sheds each month as litter for the cleanup crew.
- Soft leaves
- no
- Soft new growth that hungry isopods will nibble.
- Full size
- 5.5 cm tall, 10 cm wide
- Its size when grown, before the lid stops it.
Care
- Day length
- 6 to 12 h
- Substrate
- Dry
What kills it
- overwatering / root rot
- humid still air
Description
It is a common choice for desert bowls alongside echeveria and jade. It still wants dry soil and moving air. Sealed, humid jars rot the roots, so keep it in an open dish.
Also called zebra plant (haworthia).
