It's meant for growing plants separate from the other plants while still being in the same tank. I just throw a couple trimmings in each week, and in 3-4 weeks I end up with a ball of monte carlo the size of a baseball.May I ask what that little glass pot thingy is and where you got it from?
I got it off amazon for $11.
