Smaller white-moss

Leucobryum juniperoideum

ModerateFine in a closed jar

Smaller, neater pale cushions. Greys when dry.

What the simulation uses

Light
1,000 to 6,000 lux
The brightness it grows well in.
Humidity
65 to 95 % RH
Air moisture it is happy in; below the lower end it dries out.
Temperature
10 to 24 °C
Comfortable range; outside it growth slows.
Dies at
below -5 or above 44 °C
Days beyond these temperatures kill it.
Soil pH
4 to 5.5 pH
Soil acidity it prefers.
Grows up
0.06 cm/month
How fast it gains height in good conditions.
Spreads
0.04 cm/month
How fast its edge creeps outwards.
Thickens
1 %/month
How fast its cover fills in on its own ground.
Copes with wet
fair
How well it stands soggy soil; poor means rot comes quickly.
Copes with still air
fair
Sealed jars have still air; poor means grey mould finds it.
Copes with shade
good
How well it holds on in dim light.
Copes with drying
good
How well it survives the jar drying out.
Water use
0.03 ml/cm²/day
Water that evaporates off the cushion each day in room air.
Holds water
0.3 ml/cm²
Water a cm² of moss soaks up and keeps.
Grows on
soil, stone, wood
Where it can take hold and spread. Moss that cannot grow on stone thins out there.

Care

Day length
10 to 14 h
Substrate
Moist

What kills it

Description

A close cousin of the larger cushion moss, it copes with a little more shade. Waterlogging, lime and stale wet air are its main enemies. Keep it moist with some fresh air around it.

Also called cushion moss, small pillow moss, bun moss.
