Ah, growing cannabis isn't quite like growing tomatoes. Growing tomatoes is something that a tomato plant does more or less of its own accord. Cannabis really wants to be 15 feet tall and to produce lots of little seeds. Getting it to exclusively produce flowers requires a bit more effort. The 15 feet tall thing may also require some adjustment. What I'd like to do is to create something about refrigerator-sized whic…
Outdoor varieties do grow that tall, or more. Indicas and modern hybrids tend more towards about 5 feet, but it all depends on training, pruning, whether you use clones (every serious grower uses clones, not flowering a single plant grown from seed). The seeds in your crop only happen if you have male plants, or a problem with hermaphrodites. Most people cull the males or use female clones. If you have a female plant…

This is probably what I would consider to be one of the key differences. Because of prohibition, there was a great deal of what we might almost call scientific research into maximizing yields. A tomato is pretty much a tomato any way you slice it, but the hemp growing on the roadside and the product of the expert grower are hardly recognizable as being from the same plant. I don't think humans have quite the same relationship with very many other crops.
I think the main appeal of an automated grow cabinet would be that it's relatively difficult to keep temp/humidity/CO2 at ideal levels without a fair amount of investment in HVAC. Monitoring TDS and pH is almost too easy not to do, and being able to adjust those automatically is probably trickier than it sounds, but tractable. Setting up truly ideal conditions for cannabis cultivation requires a lot of planning, and dedicated space. But as you say, this isn't very different from the home/small batch brewing scene, and there should be a similar market for equipment.
