Conversationally with a plant person, I would absolutely NEVER tell you what's in that tub. The water looks like someone pulled a blue baby out of it, and we are not going to discuss why. I dropped a felt-tip pen in there. It looks blue now. Moving on.

Let me be upfront about something: there is no such thing as a bug-free greenhouse. Anyone telling you otherwise is either lying or has one plant on a windowsill and is calling it a collection.
