is the opposite true
Not really (at least not in the way you are thinking).

t is the time experienced by an object at rest, t' is the time experienced by the quickly moving object. If you plug in 0 for v, you find that t = t'

or would we practically have to be stopped relative to the universe
The universe does not have a velocity you can be stopped relative too.

light years from any source of gravity
Your body is a source of gravity.
What you could do is put your plants somewhere, then fly around in a space ship or whatever at a rate close to the speed of light (c=1, v=.99999) for what you think is 1 day (t' = 1). Then come back to the plants and find that they experienced a much greater amount of time (t would be about 224 days in this example).
