Dwarf Hairgrass Problem

what's your lighting power? 3 gallon usually don't have high this plant needs medium-hight direct lighting. you should avoid planting in shaded area.

mine grew nicely but won't spread. maybe beacause i use bigger and random substrate (2-5 mm) with laterite only as root/base fertilizer, lesson learned. they say the finer the better.

Sounds like I have the same problem as MichaelG. I also have eco-complete, roughly 2wpg, and use Excel.

it loves high light, co2 and a rich soil plus ferts. with med light (2.4wpg), min c02 and no ferts, in a 15g, it grows pretty slowly (this is my CRS tank so plant growth is not the goal). in my planted 120g with high light, co2 and daily ferts, it grows like a weed. both use ada aquasoil. tried it in a low tech tank without ferts and co2 and it didnt grow at all.

I have it in a low tech tank sitting by a window and a soil substrate.. It's growing slowly.

Can anyone suggest a very small co2 injection system that I could use in the 3g tank?

you might want to consider trying a different carpet plant.
even with DIY Co2, eleocharis parvulus grows painfully slow.
