WP_query() Simulate Missing “NOT” relation to Reverse Results?

I believe you could use NOT IN for the operator to achieve this along with switching some of the relations from ORs to ANDs.

array (
  'taxonomy' => 'plant_category',
  'field' => 'name',
  'terms' => 'Popular (home)',
  'operator' => 'NOT IN',
),
