Indeed, I had said something of the sort before I edited it out. The fact that it ranked so high on HN for so long, and got so many upvotes simply goes to show that using Arduino is an effective way of getting attention from HN. The the OP: As a matter of constructive criticism, you speak about how much you've gained from the open-source hardware community, but the hardware you sell, which by your own definition is based on this, seems to be closed-source. Your blog, thus-far, appears to offer little new content and seems to re-create common content from others. It would be most helpful for the community if you would explore what contributions you could make that would, perhaps, be new information for many. Here's a suggestion or two: consider publishing the hardware schematics, and talking about your "wireless communication protocol" between the Grow nodes and the host station. Talk about what the software looks like, what challenges you faced, and how you overcame them. ... just a suggestion.
