I like this idea and will probably do it. For outdoor grow when should I do this .... after last frost of season I would assume at the very minimum.

As far as cameras... come on people have you done nothing on the sly before? It's a finger hole in dirt and drop a seed. It's easy bend down on one knee and tie your shoe and at the same time drop the seed.

As far as kids go - well I have kids and have seen them do some bizarre stuff but as of yet they have never eatten a random plant they find in the yard..... well yet.

In my city they have flower hangers on the street signs in the summer. How beautiful would that be to see a pot plant peek it's head out of one of those?!
