How to get dwarf hairgrass to carpet


I have a 10 gallon dirt tank. I have diy co2 running, and 2 of these 10 watt bulbs in the original hood: http://www.aqueonproducts.com/produc...scent-lamp.htm

I put in some dwarf hairgrass about a month ago and it hasnt done much of anything. Most of it died off, and the stuff that remains slowly grows taller if I trim it, but doesnt send runners. My stems plants grew like crazy and so did my crypt, but I cant get this stuff to spread at all.

Does anyone have any advice? Do I need more light?

I have a high tech 55g tank and I got a few runners, but it was impossible to keep clean, so after about four months I took it out of the tank, it needs strong light and co2, but still will not grow that fast.

You have the right conditions to get it to grow. To get it to spread, plant it in small clumps with 1-2 plants per clump. Position the clumps in a grid or checkerboard pattern and it should spread faster for you. Don't be tempted to trim just yet. Let it produce a few runners first before trimming.

The bulbs you are using are for Marine tanks, not for freshwater plants.
These bulbs (should be) better:

or any bulbs that fit into your hood at ~6,700K

I've used the 50/50 bulbs for growing easy plants such as moss and some stems for a while and they love it. Not sure if it strong enough for hairgrass though.

you just gotta let the plant go... I planted in clumps of, probably, 20, because I'm too lazy to separate them all out. They're tossing out runners now, but still not nearly close to filling in.

I have a couple of big clumps in my 50 that have been there about six months. I've had to trim them down because of a BBA problem. Had the same slow growth problem, though. Then, about three weeks ago, it went crazy. Started sending out runners and growing like it never had. I use CO2 and Excel, with root tabs. I guess patience has been the key. I wish I had known about breaking them up and planting them in a grid as I would have done that...

I read about starting DHG dry on the Barr Report and have a batch started this weekend. It is supposed to reduce the start time exponentially. I have a tray with a 2" lip filled to 3/4 inch with potting soil. I bought a 4x4" section of the grass and cut it up into 1/2" squares and planted it in the soil. Saturated the mix so that the water fills the soil but does not cover the plant. I have a normal desk top florescent lamp on a timer above it. Also, the tray is placed near a window with lots of sun. I am supposed to see fantastic results in two weeks, we will see.

what kind of gravel, and DHG loves root tabs. It's been a few months in my tank with Netlea Aquasoil, root tabs, excel, 2x13w Home Depot CFL lights and I have runners going everywhere. It will probably take 6 months to fill in, but it's getting there and low light and now CO2, I expected that.

I have Dwarf Hair Grass growing and sending out runners in a 2 gallon bowl. No Co2. 5000K 19W CFL @ 8 hours per day. Substrate is Amazonia. Not fast but steady growth. Initially, I believed I would not have any success with DHG. Good luck.

Before I buy these, are there any other bulbs that would be even better? Hopefully that would fit in the same fixture as these.

You need to start off with something like this and plant a lot of them in addition to the lighting aspect.

all you need is patience

it can grow in low-high light...co2 or no co2...a lot of ferts or very few (though ferts should almost always be "high" for most tanks)
DHG is a very low maintenance/easy plant

i grow some in a window sill in 2 jars and a vase from 3 sprigs

the vase only gets indirect sunlight so it took a solid 6months before it filled in (and its very tall ~4")

in my jars that get direct sunlight (no co2) it took about 2months to fill in and it is short ~1"

I just moved it over to my high light/high co2/high fert tank and it hasnt done much (a few runners here and there in a months time)

but in a few months it will spread like crazy

PATIENCE is what you need...it starts out slow and then explodes with growth
