Help With Research Paper! Java moss

Not sure if the picture shows up since I'm using my phone but I'm doing some research on java moss growing in different conditions.

I have a 1 gallon with no heater, no life of any kind or filtration. Just stagnant water, lava rock and java moss.

I fill up half the tank with water from my main aquarium and fill the rest with dechlorinated tap water.

Does the aquarium water provide enough nutrients or should I get a small mystery snail or something? I want to make sure my java moss gets enough nutrients.

Thank you!

A handful of top soil capped with gravel or sand will do for nutrients.

on the other hand you could leave it just as it is and see if it grows at all and use that info as another variable.

That's exactly what I was thinking. If it dies, it dies. I have tons of it so a small clump is nothing. I just wanted to know the bare minimum required. Thanks for the help though guys. More suggestions are still welcome!

By the way, this is for my botany class

imho a handful of dirt isn't very conducive to accuracy...
Since you seem like you have access to a lab, why don't you go ask the chem department if they've got any kh3po4, kno3, k2so4, etc etc and add those in gram increments? Usually they'll let you do that. Java moss doesn't really need substrate... you could just add those dry ferts and call that another variable.

btw what's with the rock? For raising kh or something? If so, you might want to pick up a bit of caco3 while you're at the lab. Use that instead?

whats this paper suposed to prove?
how moss grows in dif conditions?
if this is the controle you shouldent add anything besides dechlor tap water.
the others should have difrent amounts of ferts added and difrent amounts of light.

You got it jreich, to resound:

So what is your hypothesis with this? If this is a scientific experiment then you should really have multiple setups with only one change in nutrient regiment per a set up (i.e. dose nitrates with one, phosphates with another, etc.), applied in the same way, as well as a control. You can only change on variable at a time otherwise you'll never know why you are getting the results you are.

are you a sink or source?
