Seductive entodon

Entodon seductrix

ModerateFine in a closed jar

Very glossy, worm-like mats on limestone and logs.

What the simulation uses

Light
2,000 to 15,000 lux
The brightness it grows well in.
Humidity
50 to 90 % RH
Air moisture it is happy in; below the lower end it dries out.
Temperature
8 to 28 °C
Comfortable range; outside it growth slows.
Dies at
below -25 or above 44 °C
Days beyond these temperatures kill it.
Soil pH
6.5 to 8 pH
Soil acidity it prefers.
Grows up
0.02 cm/month
How fast it gains height in good conditions.
Spreads
0.1 cm/month
How fast its edge creeps outwards.
Thickens
1.25 %/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
fair
How well it holds on in dim light.
Copes with drying
good
How well it survives the jar drying out.
Water use
0.04 ml/cm²/day
Water that evaporates off the cushion each day in room air.
Holds water
0.2 ml/cm²
Water a cm² of moss soaks up and keeps.
Grows on
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

It grows on limy rock, logs and tree bases in eastern North America and stays under a centimetre tall. Pair it with limestone rather than peat, since acid peat harms it. Keep it moist but never sitting in water.

Also called round-stem silk moss, cord glaze moss.
