New World Little Gardens

Hi there, I just found a load of these little garden planting kits, I assume they are old as this is an old promotion right. Do you think I could still plant and harvest them? Or will they be too old and expired?

The soil tablets have a best before date of 12/11/2018 and the seeds and pots have a best before date of 12/03/2019, so you still have time to start your Little Garden. Happy planting!
