I have Java moss tied down to 2 dritwoods in my tank for the last 1 month. Have DIY CO2 and 2.5W/g lighting. Its a 2 ft long tank and 15" deep. The moss is dull green and turning brown. I also dose 2 ml regularly with Plant Magic liquid fertiliser. Have an internal power filter and a sponge filter. My Amazon Swords and African Tiger Lotus are doing exceedingly well, not sure why the Moss is not thriving. Any suggestions?

I second Kshitij on the temp. I used to have the same problem and did not know why the Moss would neither grow or turn brown, until I realised and was advised to try and lower the tempreture as well as (if possible) keep the water clean(with multiple water changes).
This has changed most of the moss I have to lush green with a fantastic growth.
I know its a challenge to regulate tempreture in Mumbai to less than 27. I use multiple methods though I would not say that it would work for you nor recommend the same.
1. Ice Cubes
2. Keep small Water Bottles(Ones you get on flight) in the Deep-Freezer and then once then dump them in the tank.
3. Keep the Hood open with the Aircon on

As Royston mentions for any aquatic moss to grow well, it needs mildly clean acidic water between 21 and 24 C ideally. Nutrient contents need be moderate, as mosses uptake isnt as rapid as more complex flowering plants. In my experience I've also seen it needs moderate light. IMO, it's not really suitable for low light tanks. It'll survive, even grow a bit; but you will not get that beautiful green scaffolded growth.
IMO, moss in Mumbai without a chiller is quite a challenge.

One more important thing to consider with mosses is clean water and the moss should itself be dirt free.
Let me explain this in detail.
Efficient filtration with as much media as possible is best for a planted tank, usually internal filters arent adequate in terms of media(sponge/filetr wool) w.r.t tank capacity. The sponge clogs up quite soon(and needs frequent cleaning) else it become inefficient. And once it clogs the particulate matter doesnt gets trap in there and hence afloat and is constantly rotated by flow from the powerhead. These dirt particles make way into the fine leaved plants and especially mosses and get settled there. Added to this either excess of fish population or overfeeding or both contribute to excess of detruitus. Once this waste particles starts covering moss surface, it get deprived of lights and other nutrients it takes in from water and this part of moss slowly browns and dies out and the further strands from this loose connection and the whole structure becomes weaker and weaker. If anyone is not sure about simple structure of moss, pleas do a little reading, the resources explain better than I can.
Same holds for delicate delicate and small structured plants, for example HC, hairgrass, glosso, etc.
To overcome this, firstly you need a good filtration with lots and lots of media, a canister filter is the best choice, you can load in various mediums like bioballs, ceramic rings, etc for max performance.
Second, regular maintenance. Siphon as much detritus as possible from the base(gravel) on regular basis.
Dust the mosses off dirt, you can do this by gently waving your hand close to the moss clump, this generates a brisk flow that pushes out the trapped dirt, siphon his from the other end.
Keep the mosses trimmed and under control. Same applies for compact FG plants.
Another important aspect is how you tie the moss. Place a thin, tight and uniform layer over surfaces(wood, rocks, etc) and tie it firmly. This not only conserves moss for your further tanks but also helps moss to hold on surfaces well. Heres how you do it.
Mosses grow in all ranges of lights from low to very high. The structure and growth form varies. In high light you have more desirable compact, tight and thick growth while low light gives lean stringy growth.
high light might be tempting hence...I would like to moify an well-known quote and present it here, "With high light comes high responsibility' as you have to maintain consistent levels of nutrients(inc CO2).
Last but not the least temperature, a known fact nowadays.
Keep it below 29 for all planted tanks, though 29 the extreme(in uncontrollble situations, like in midst of Indian summer), best range is around 24-26, safe for all kinds of plants and fishes. Some methods for cooling down mentioned above.
Bottom line, keep it clean, keep it balanced(interms of light, nutrients and temperature) and you should have a moss growing lush.

i had bought some java moss about 3 months back..kept some in the tank and some in a bowl outside..both of them grew very slow,with some leaves turning brown as well..i even had a diy co2 running in my 10 gallon 24/7..still the moss did not show any signs of growth..until it was the moss which was outside which is finally showing astonishing growth of late
the rains have also come down hard,which might have helped as well i guess the moss intially is a slow starter..

Thanks for the advice. Really helpful. Currently, am more or less resigned to see the moss die slowly as I am in ofice more than 10hrs per day and so cannot keep regulating the temp. Most methods above require regular intervention. The only thing I can think of is to take the metal hood, get sojme slits cut into it for the air to circulate and the heat from tube to escape.
I am toying with the idea of upgrading to a 3ft or so tank, am on lookout for same in WTB/WTS/WTG forum and the moss was basically being grown for that tank. Many experienced people (including Mr. Carey from whom I just bought a bag of ADA Amazonia II) recommend cannister filter, but the cost becomes a deterrent. Can anyone advise via PM where I can get a good deal on a good cannister, I was thinking of a overhead filter as an alternative.

Well, I'm quite surprise nobody recommend using fan to cool down the temperature
Since you are thinkin of making some slits on the hood...then might as well make a hole for PC or AC fans. If you can get AC fans that would be great, as you can directly plug in to the power supply, otherwise you will need an adapter for the PC fans. With fans, you can bring down the temperature to 2-3 degrees....that would be good enough for Java moss :D
