Don't call yourself stupid! :thumbsup:

If you go a day without learning something new... you didn't do enough that day. :jointsmile:

In my opinion you need to:
Trim the cups... Don't trim the cups baby,
Trim the cups... air needs to flow over,
Trim the cups... Don't trim the cups baby,
Trim the cuuuuuuuuupppppppppppppps.

Chaaaaaa (does jazz hands) :hippy:

No seriously though, that's a decent amount of space between the soil surface and the cup rim. That air is just going to hang out there and get funky :hippy:. It would be like spending all day in a super ripe "dutch oven" (and I'm not referring to the cooking vessel).

Mmmmm... I can smell it now.
