Growing outside in plastic grow bags

Has anyone used any of the black plastic grow bags? Pro's or Con's anyone before we plant. Should we use the plastic plant pots or plastic grow bags?

As far as deciding between plastic pots and grow bags....I would go with grow bags. ONLY BECAUSE, you can sqeeze more into a room because you can sorta squish the bags in there...

But in all honesty I would go with Smart pots.

I swear by them.
