Guide UI annoyance

[arthurpaulino]

If the user hasn't configured his own garden parameters yet, the guide UI behaves in an annoying way:

I think it should display a spinner like "Set Sun / Shade for #{user.garden.name}" instead of displaying a message with the word "null" in it.

Also, and this may be just a personal preference, the message that's displayed onHover stays up for 1 second (I think) and I find it pretty confusing. Why not just remove that delay? What do you guys think?
