This is a really fast and dirty script for gardening, its definitely not perfect, with a little more work you could probably actually automate it even further... but for now...
I tend to only do my gardens once a day, so this is mostly tuned towards full of weeds and bone dry hahaha, you could expand things out a bit and have values for each level of watered or weeded probably, but for now it will work best on the most bedraggled of gardens ;)
15/07/20 - updated to include some more capture patterns for various states, and a dirty implementation to water from the mid point message, the challenge there is that the same message could require one or two waterings to full, this should be at least mostly working now.
16/07/20 - tidied up a silly recursive script error with the tilling step, switched watering, harvesting and tilling to a single pass per execution and added some short waits to prevent overflowing, hopefully everything should be working fairly well by now.
