Some parents aren't keen to talk to kids about marijuana - but others are embracing a show-and-tell approach.

For those truly committed to the idea of showing your kids that cannabis is just a plant, a kid-friendly gardening kit called My First Grow can teach your little ones the kids the rudiments of growing cannabis (the non-psychoactive, hemp variety, of course).

"At My First Grow," it says on the web site, "we believe Cannabis should be legalised and that children and adults alike should begin educating themselves about the myriad of uses and benefits it can provide. Our Hemp grow kits are the perfect first stepping stone in a journey of Cannabis discovery."

The kits include seeds, soil, a planting container, and instructions on how to germinate, water, and grow cannabis, as well as stickers bearing a cartoon weed-leaf. My First Grow is the brainchild of a British cannabis activist known only as "Greg," who tells Broadly the page has been shared over 10,000 times, and he's shipped kits all over the world from New York to Brazil.

To be clear, the site is not encouraging young people to consume cannabis. It is also not encouraging adults to do it in illegal jurisdictions. A disclaimer on their site warns that actually germinating Cannabis seeds, including hemp, remains illegal in the UK and many other countries, and that the seeds are a "collectible adult souvenir" and "for educational purposes only."
