I want to purchase a 100' polytunnel greenhouse and grow a shitload of weed in it. I figure that if i give each plant 16 sqare feet of room, then i will be able to grow 187 full sized plants. What do I need to worry about in terms of law enforcement?

Busting you is the one worry you should have. I don't think you need to worry about them coming over and smoking it all. I don't think they will give you a citation for poor ventilation or using chemical fertilizer when they want organic weed. Nope...busting ya is the one worry.

thats what i figure, it seems so easy to fork over four grand for a pre-built greenhoue and grow a shitload of weed. This begs the question why isnt everyone doing it? Im sure there is a reason and I want to know what it is.

see previous answer as to why everyone isn't doing it.

but how do they get busted, there seems to be indoor grows everywhere, and a greenhouse sure seems a lot easier than dealing with lights, and wattages, etc.

its because a greenhouse sparks a person's curiosity.(gee, i wonder what their growing in there?)

a properly concealed indoor growroom will never do that.

but, a properly concealed greenhouse will go undetected.

thats why i'm working on a "stealth greenhouse" that will be virtually undetectable.

muuaahaha!

does law enforcement have any right to look in a greenhouse, I know they can legally walk around your property and long as they dont peek in your windows or violate your home curtailment. Its called the open feilds doctrine, its bs i know, but its the law in the US.

[river rat01]

they have to have a search warrant to enter your property,
unless your dumb enough to invite them in.(never do that).

the main point is, just dont give them a reason to suspect you.

no smells, no light leaks, no sounds, no suspicious looking shit.

[johnstuartmill]

actually they only need a warrant to enter your home, they are allowed to search your land without one. Its called the 'open fields doctrine' the Supreme Court ruled it constitutional because no one has a reasonable expectation of privacy on thier land, only in thier home and the curtailment of the home. Without a warrant or any sort of notification a LEO could hop your fence and look around your yard, go through your garbage, take samples of suspicious items, etc. Many people think they have privacy but the Law has made sure that there are only a few places where a person has, legally speaking, any privacy.

here's what i found on wikipedia:

Distinguishing open fields from curtilage,
While open fields are not be protected by the Fourth Amendment, the curtilage, or outdoor area immediately surrounding the home, is. Courts have treated this area as an extension of the house and as such subject to all the privacy protections afforded a person’s home (unlike a person's open fields) under the Fourth Amendment.

An area is curtilage if it "harbors the intimate activity associated with the sanctity of a man's home and the privacies of life."[7] Courts make this determination by examining "whether the area is included within an enclosure surrounding the home, the nature of the uses to which the area is put, and the steps taken by the resident to protect the area from observation by people passing by."[8] Theoretically, many structures might extend the curtilage protection to the areas immediately surrounding them. The courts have gone so far as to treat a tent as a home for Fourth Amendment purposes in the past. [9][10][11] It is possible that the area immediately surrounding a tent (or any structure used as a home) might be considered curtilage.

Despite this rather broad interpretation of curtilage, the courts seem willing to find areas to be outside of the curtilage if they are in any way separate from the home (by a fence, great distance, other structures, even certain plants).[12]

sounds to me like a greenhouse is safe.
esp. if you have a fence around your property that defines your curilage.
