The Great Java Moss Experiment

Experimenting with Java Moss… Day one at approximately 12:00 PM, two pieces of approximately equal size of Java moss placed in 2 quart jars. The two jars are placed in a south facing window in sunlight. Both jars are open. The jar on the right contains an air stone to create water movement. Well, the other jar is left alone with no water movement.

I am testing the growth of the Java moss. I saw on another website, where someone left some Java moss in a jar in sunlight and it grew like crazy to fill the entire jar. http://www.plantedtank.net/forums/33-plants/131018-new-way-grow-java-moss.html I wanted to try it for myself. I decided to turn it into an experiment by having two jars, one with just the java moss and One with some water movement. I want to document the growth in each jar.

I also forgot to mention I did put Seachem Florish in each jar.

Photo from day 18....... Not sure if there is much of a visible different from day 1.

I have added water and Excel a few times. I have stirred them once or twice, so the moss gets sun.

Don't bother adding excel, most mosses hate it. Some added nutrients wouldn't hurt, but then a lot of mosses grow well in nutrient lean environments too.

The great thing about mosses is they're pretty tolerant to being neglected (aka no nutrients/co2/co2 supplement) as long as they get enough light, windowsill is plenty if you rotate jar or stir moss maybe once a week.

I had fissidens aka phoenix moss for a long while, it tolerated high doses of excel (0.6ml in a 2g tank(3x normal dose) daily) and medium light.. maybe once a week I'd throw in flourish (but the floating plants would hog it).  It grew great! ...Until my mother visited and she left the tank light on 24 hours (she decided to force the light on to make the room brighter to read a book then never turned ti back to timer mode) =,= got hair algae I could ever get rid of (fissidens doesn't tolerate hydrogen peroxide, potassium permagnimate, or bleach treatments) so had to get rid of it >.<

it was my favorite aquascape too

WillowBaby, thanks for posting. Good to know about the Java moss.  I've got a suitable window, and I'd rather not plug in another thing that adds to our electric bill if I can help it. 

 

AquaAurora, the plants you sent are doing great. 

Thanks.

Sorry about not updating sooner… I've been busy with my internship and preparing to graduate this December.

I will try to add an updated picture soon. Here is a quick update… Both jars are growing, but I have to say jar 2 with the air stone has had so far far more growth then jar 1.

I'm going to try and keep this experiment going at least in till Christmas. I have done one major water change because I found several snails in the jar( not quite sure where they came from). I do have to serve somewhat regularly add more water as it evaporators. I normally try to add water from my 15 gallon which currently has live plants and a handful of red cherry shrimp.

Again I will try and give you a photo update this weekend.

Day 72 of The Great Java Moss Experiment. Can you guess which ball of moss came from which jar? There is definitely a lot more java Moss in jar 2. I do even say that jar2's Moss looks healthier and greener than jar1.

Doesn't surprise me. If you have a creek nearby, try and find some aquatic moss and see where it grows. A lot of stuff around here grows in well oxygenated water. Stuff in the stagnant pools tends to be brown and/or yellow.

Were the temperatures different? The moss on the left looks like the sort of growth you end up with when you grow it in water above around 24-25 degrees Celsius.

They have same or similar temperatures… Both mason jars are sitting side-by-side in front of the same window. I just measured the temperature of both jars each comes out at 67°F

Merry Christmas and a Happy New Year…

Update from a few days ago.

Day 84 of the Great Java Moss Experiment. The moss from jar 2 is clearly doing much better then jar 1. I am going to keep this experiment going until 100 days which would be January 4, 2017.
