I turned down a job there a long time ago, I did ontologies academically so I already knew they didn't work for what they were trying to do.

A rough ballpark on watering cycles is usually good enough. I'd watch the leaves to give you an idea. I'd stop watering and wait until the leaves show signs of under-watering and then use slightly less time as my watering period. I'd guesstimate based on your setup that the period will be measured in days.
IMHO if you're going to have that much set-up you might as well go hydro.
And, as I'm assuming the real aim is to build cool things perhaps you could use Deep Learning to do leaf classification (Over Watering | Under Watering | OK). That way you could use a webcam to control the watering instead of the sensors. Knowing your watering times and regular classification samples you could use a fourier transform to help identify the optimum watering period. Perhaps someone could do this as an API service. I do Deep Learning on images as my job so if you want I could tell you how to create the training data and once you have that I could train a classifier for you.

Drain the water back into the reservoir (use a simple filter to prevent damage to the pump) and just use a schedule for watering.
I used a mechanical timer switch for 15 mins every hour for my hyrdo setup. For soil, such tiny plants, and no lights you would need far less frequency. A general rule of thumb is to give it enough time between waterings to let it get a bit dry.

Amazon has bigger fish to fry than eBay. Amazon can always focus on second hand market place later while leveraging their infrastructure to ensure a win. My bet is that they will take a long time to get around to it. In the meantime phone based and social based have a pretty good shot at competing. This will also take a long time.
eBays efforts to take on Amazon at being Amazon is a total waste of what little focus they have. Like Yahoo, one of the best perks of eBay is that it's hard to get fired. It's very relaxed and people are quite comfortable - why risk an easy / safe job by taking a risk doing something innovative. After a while innovative people get jack of it and leave and all you're left is the lazy and incompetent. There are pockets of excellence within eBay but they're getting smaller. There was a potential for a turnaround when the stock price was $10 but at $30+ no-one is interested.

We did customer analysis to show that existing customers were leaving faster than new ones were coming in. Usually people have one bad experience and never come back. They still didn't care and given their culture they will never care until their stock plummets or a real competitor comes along.

The following addresses his reasoning on why Texas isn't as backwards as would be expected; https://www.cs.utexas.edu/users/EWD/transcriptions/OtherDocs....
And I think the Dutch TV show goes into specifically why he had to leave europe in order to pursue his ideas.

I really enjoyed my time in the church. There is huge pressure to conform in one area but this means your free to be yourself in others. I was a nerd and constantly tormented for it outside the church. (The US is much nicer to nerds than those in my country where it considered a civil duty by other children to beat it out of you). Inside the church I was treated like a normal person. Similarly, Dijkstra had to leave Europe to escape a 'religious' academia and found refuge in 'backwards' religious Texas.
There is a natural human tendency, an emergent behavior, to self organize into 'religious' groups. I see the same behavioral patterns in environmentalism, veganism, feminism etc. By keeping 'religion' to religion there is less of for it in others areas.
I left the Church quite young because I didn't need it anymore and thought the church was stupid. I still liked the people in it.
Obviously if I was gay I would have a different story.
