Just got a 10' x12' x 10' height polycarbonate greenhouse with aluminum
structure kid for the wife:

The instruction is to excavate the area to a depth of 5" and bury the
greenhouse base frame in it with gravel. No other anchoring method is
provided. Even though I'm located in the San Francisco Bay Area with not
that much wind but I'm concern about wind loading after installation. Has
anyone installed one of this?
