During a conversation with my mom the other day she told me she has started selling this product and it immediately jumped out at me as something that would be great for prepping. I have attached a link below but it is essentially a self contained gardening system for growing fresh, organic produce with nothing but water and sunlight. It is ideal for folks in urban areas with limited space. I sent the moderators a message three days ago asking if this post was permitted but have not heard back. Figured I'd just assume take the slap on the wrist if they need to remove the post. Anyway in the interest of full disclosure, yes my mom does sell these so yes if you buy one you'll be helping her make a little money (she is retired,) but also like I said I think it is a great product anyway so check it out and let me know what you guys think.
