I too had a problem with my cocopod bring too wet. Fortunately I didn’t get mold. I just moved it as high in the tray as possible and eventually it got better.
Like you, I’m new. This is my first grow; one in a grobo, one in a pot outside, and I just took the third out of the grobo start and plan to put it in my tent (it’s outside in a pot at the moment).
I look at this round as a learning grow, so, I don’t expect the buds to be a that great. For my next grow, I plan to do a better job selecting seeds that are shorter. I also plan to stay away from autoflower seeds so I can have a bit more control.
I too will likely expand to more grobos in the future. I like the minimal maintenance aspect.
