The mysterious, unnamed event
When you click on this event in the parking lot, it'll open up a tab that has 10 boxes in it.
Each box has 5 items that you can donate to it, some boxes might have overlapping items, but none will have the same 5 items.
Once you donate an amount of an item to a box, you'll be able to choose how long the box will run for, and how many points/second it'll produce, depending on how much of what item you donated.
For example, if you donated 1K of cherries, you might be able to run the box at 6.5H at 15 points/second, or you could choose to run it for 3 hours at 25 points/second.
Of course, the time limit for the running duration of the box would be 8H max and 1 hour min, once it ran out, 1 ingredient would randomly change but everything else about the box would stay the same.
Also, a longer time duration will produce less points/second than a shorter time duration as shown above.
What's special is that depending on what items you donated and how long you run it, you'll get varying % chances of producing 5 different items, 3 of which will be disclosed, while the other 2 will be "hidden", though you do have the option to find out what they are with gold.
So going with the 1K cherry example from above, you could have a 1.2% chance of produce a gml/hour, a 2.6% chance of producing 10 super fert/hour and a 3.4% chance of producing a special wildflower seed/hour, whenever you open up the event, there'd be a pop-up showing you what you produced since you last opened it up 
Also, to produce (or have a chance of producing) an item, you would have to full-fill a requirement, whether for a gml that's for the box to be put in for at least 5H's (5H's at least at the beginning of the "cycle" for that box, if you put it in for 6H's, you'll have a 1.2% for the whole 6H, not just the 1st 1H) , for seaweed humus you'd have to run it over 40 points/second, for a special wildflower seed you'd have to run it over 20 points per second, etc.
For some random boxes you could also have a chance of producing a number of "Event Tokens"/hour which could be used to buy stuff in a shop.
