Grass concept and design ideas

Below I have shown how the text could look on the inside of the box. I have placed the text at the side with the idea that next to this I could add instructions of how to grow the grass once the snacks have been eaten. I would like the instructions to be illustrated to go with the illustrations which already feature on the little food tubs.
The idea is that once you have eaten the snacks, the seeded paper would be underneath in which you water it and grow the grass. You can rip the lid off the box so the bottom would be a form of plant pot for the grass to grow in. Obviously if you water the seeded paper the box would also go soggy and fall appart so I will need to come up with a solution to this, maybe some kind of plastic sheet or a plastic tub inside the card box.

Another idea I have is that the tubs which the food comes in could be the plant pots. In the graze box you could get little packs of seeds which you place in the tubs and grow the plants. Most graze boxes come with 4 tubs of snacks so this will allow the customer to grow 4 small plants which can then be taken out and place around the house, or stay in the graze box to sit on the office desk. Here is a mock-up i've made to demonstrate this:

I really like the idea of the graze box being re-used for plant pots and it would make sense for the box to come with everything needed to do so. I think it would be a good idea also if what was grown could be edible rather than just plants or flowers, this would then encourage more healthy eating eg fruit, veg, herbs etc however it would have to be something which is small in order to fit and grow comfortably inside the graze box. I need to research further how this could work and consider things such as possible health risks of food products and plant products being in the same container.
