Since pot is legal to grow (either freely or with a medical license) in California, Colorado, Washington, Oregon, New Mexico, Nevada, Alaska, Arizona, Massachusetts, Michigan, Maine, Delaware, Georgia, Maryland, Montana, New Hampshire, Rhode Island, Vermont, Florida, D.C., and Hawaii, I'm not sure it's so "unacceptable" anymore.
Says you. I fail to see any reason see why wine making is morally better than growing cannabis, or why alcohol use would be morally better than cannabis use.
One might be more common, but it's certainly not more moral to do.
And a lot of people I know would be in the same boat. Is everyone like that no of course not, but I'd venture to say a significant portion of people are(not necessarily majority, but a lot)
In the states that have legalized marijuana to some extent, this may be less of a problem these days. That still leaves a large amount of states where this may still be an issue, and potentially create hassles. Kansas is not on your list, for instance, and it was pretty easy to Google a similar incident there: http://www.kctv5.com/story/23951053/leawood-family-seeks-7-m...
This is unfortunate, because high tech gardening absolutely has applications beyond weed. Even if it's more niche / luxury (for instance, restaurants having indoor gardens to ensure a supply of super-fresh veggies and herbs) or hobbyist (like the African violet grower comment below... even largely idiot-proof versions like the Aerogardens exist for this market) due to the economics... these applications do exist.
The rate of growth is something else to consider. From two states (Colorado and Washington) last year to at least three more this year (MA, ME and CA). And I didn't even notice that DC, NV and OR crept in as well.
Yes, some social stigma exists, but it's on its way out. But I agree with you as far as: It may never reach full U.S.-Wide legalization. And employers may never get over it.
Note though, that medical as > 50% adoption by state in the U.S.

High profit crops are needed to push the state of the art environmental control designs forward and costs down for other crops; which will become increasingly common as systems mature and costs decline below that of traditional production methods.
