Are they 2 types of dwarf hairgrass? 1 that grow vertical , 1 that grow runners?

[marimo]

I know it sounds dumb .. thats what the LFS told me when i ask whats the difference between the $2 and $3 per pot hairgrass, that what he explain to me.
$2 is the vertical growing
$3 is the sideway growing

what i know is the vertical growing , just trim the root and plant

the runner trim the top part and roots and give sufficient light and CO2 and it will grow side ways.

japnese hairgrass will look shorter than normal hairglass and if they grow well in high lighted condition, it will curve down

There are 4 hairgrass That I knew of
1. Eleocharis parvula (dwarf hairgrass) -> can grow up to 15cm depending on environment
2. Eleocharis sp (Japan hairgrass) -> curve leaf
3. Eleocharis acicularis -> grow long up to 30cm depending on environment
4. Eleocharis vivipara -> grow very long with plantlet at its tips

Normally at LFS, the normal hairgrass is around $2 and Japanese hairgrass is around $3

[marimo]

ya that what i thought so too
the more expensive may be japan hairgrass thats curves down and stays low
the other is dwarf hairgrass which grow erect

however at the LFS they look exactly the same as they have trim the top part and no curve blades either...

do you mean mm instead of cm?

[Shadow]

nope, I mean cm. It depend on your nutrient level. If you follow EI dossing then your plants will be very big one because unlimited nutrient. In limited nutrient level, you wont be able to differentiate between Eleocharis parvula and Eleocharis acicularis

But in a limited nutrient environment, the rate of propagation of new plantlets will also be significantly reduced?

[Shadow]

It slow down but cant really tell because I normally plant densely from beginning.
