Only when the reddest of the red states finally legalizes pot will this sort of joke FINALLY die.
OBTopical -- as these sorts of operations become larger, better control will become important, which is why I think remotely viewable controls is the way to go. Of course, eventually people will grow the stuff in fields like every other commercially grown plant and a certain class of electrician will be very sad ...
Does not matter what product is grown, we already have equipment designed for the application of growing things for products that are not questionable. There alread are all kinds of commercial greenhouses growing many fruits, vegetables, and other plants for all kinds of purposes. Many of them already use automated control systems for heat, light, water, fertilizer, etc.
I do not see 547 applying here.
Agree 547 primarily applies to livestock buildings. For those that don't ever go into livestock operation buildings, they don't really understand what kind of conditions are encountered in those places. Here on this forum, horse barns is the application that seems to come up the most. Horse barns are actually a pretty mild environment compared to beef, swine or poultry operations, I have been in enough each of those types to put some of you to shame on any comments involving them especially when it comes to what really goes on in such installations. Code and practicality do not always get along in those buildings and you sometimes need to compromise. OTOH some of you have been into enough huge industrial plants to do the same to me.
