I am a novice programmer, but full time gardener. Can someone please explain to me what the significance of this is? I can't understand what data is in the datasets and what I will be able to figure out if I do go for the 400gig download. I have lots of marijuana/entrepreneurial posts and this one seems to have gained some good interest. I am curios if someone can explain more. Thanks.
