Guerilla Expert advice needed

There is moss growing near my guerilla site. Is moss a good sign or bad sign about the growing conditions?

imo this isnt good, its a sign that the air is moist and stagnent.and in a place of low light. u want to a place with good air flow and morning sun to keep ur girls from getting moldy,a nice enviroment for moss is also a nice enviroment for mold

So it doesn't have anything to do with the acidity of the soil ?

I would avoid it for the simple fact that it will get low light, Then mold and what not is never a ++. Everything I have been taught is to get to a good spot the opposite direction of moss for ample lighting. I am sure someone else on here knows more on this to and will chime in.
Goodluck on everything man,Stay Stoned
