# Common feather-moss
Kindbergia praelonga

Beginner · Fine in a closed jar

Soft feathery carpets that spread fast in damp shade.

## What the simulation uses

- Light: 800 to 10,000 lux (The brightness it grows well in.)

- Humidity: 70 to 100 % RH (Air moisture it is happy in; below the lower end it dries out.)

- Temperature: 5 to 22 °C (Comfortable range; outside it growth slows.)

- Dies at: below -25 or above 42 °C (Days beyond these temperatures kill it.)

- Soil pH: 5 to 6.5 pH (Soil acidity it prefers.)

- Grows up: 0.04 cm/month (How fast it gains height in good conditions.)

- Spreads: 0.35 cm/month (How fast its edge creeps outwards.)

- Thickens: 5 %/month (How fast its cover fills in on its own ground.)

- Copes with wet: good (How well it stands soggy soil; poor means rot comes quickly.)

- Copes with still air: good (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: fair (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: 0.22 ml/cm² (Water a cm² of moss soaks up and keeps.)

- Grows on: soil, 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

- drying
- heat above ~25 C

## Description
It is one of the most common mosses in Britain, found in moist, shady lowland spots. In a humid tank it makes an easy carpet. Keep it damp and cool, as drying and heat above about 25 °C set it back.

Also called Eurhynchium praelongum, Stokesiella praelonga, feather moss.

Estimated, where sources were thin: growth rate; temp_c.
