no. id think if someone did do this, they would do it outside but its easier for light to come from above than to come from below.
Upside down growing: would it work?

i don't have $4000 laying around.
so if you grow outside and your plant gets rained on, does it rot and "suck"? no. its not going to be standing water. again.. gravity. it might pass over it, but its not gonna just chill there all day. nawwmean?

It might ... IF THC wasn't produced in trichome heads and instead were produced in roots or stems or branches or leaves and instead it already located where you would like it to; "drain" to.
I don't think the force of gravity is too much for a plant to handle growing upside down (they work on such a smaller scale that gravity shouldn't make a difference, it isn't like they are trying to move hundreds of gallons up a huge pipe against the forces of gravity). I really doubt that THC would grow in the roots because that area gets no light. And people have grown marijuana in those planters that rotate around a light, those plants are growing upside down half the time and they do fine.

It wouldn't, it couldn't, it can't. THC is produced in glandular trichome heads and they do not exist on or in roots regardless of light or the lack of light. They do not even exist over entire plants and they are not in plants, they are on them ... so the idea of roots producing THC is about as accurate as saying the Jamaican bobsled team is number one in the world.
CANNABIS CULTURE - An up-close look at the THC-producing resin glands of the cannabis plant through pot-ographer Bubbleman's macro lens.
If you’ve seen pictures of mature cannabis plants taken with a macroscopic lens that’s zoomed-in very close, then you’ve undoubtedly noticed the many glistening translucent resin glands protruding from the buds, leaves, and just about everywhere else on the plant (see “Stalking Trichomes”, CC #72). Most marijuana growers and readers of pot magazines are quite familiar – and some downright obsessed – with these resinous outgrowths known as trichomes. You may have also read that the sticky coating of trichomes is home to the active ingredients in cannabis – the stuff that gets you high and has all the medical benefits – tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. But have you ever wondered exactly what the trichomes do for the cannabis plant, or what biological purpose they serve?
Sticky resinous growths knows as trichomes are home to the active ingredients in cannabis. (Click picture to enlarge)Evolution of TrichomesIn nature, only the strong survive, and it is hypothesized by biologists that trichomes evolved as a defense mechanism of the cannabis plant against a range of potential enemies (1). Trichomes, from the Greek meaning ‘growth of hair,’ act as an evolutionary shield, protecting the plant and its seeds from the dangers of its environment, allowing it to reproduce. These adhesive sprouts form a protective layer against offensive insects, preventing them from reaching the surface of the plant. The chemicals in the trichomes make cannabis less palatable to hungry animals and can inhibit the growth of some types of fungus. The resin also helps to insulate the plant from high wind and low humidity, and acts as a natural ‘sun-screen’ in protecting against UV-B light rays. But since trichomes contain euphoric properties attractive to humans, it may be man who has had the most influence on the plants’ development through many years of favoring strains that consistently produce more of these gooey resin heads.
Trichome Types
Trichomes grow in numerous shapes and sizes on many types of plants. The cannabis plant has developed three main types (from NationMaster Encyclopedia):
Bulbous: This type is the smallest (15 to 30 micrometers). From one to four cells make up the ‘foot’ and ‘stalk’, and one to four cells make up the ‘head’ of the gland. Head cells secrete a resin, presumably cannabinoids, and related compounds that accumulate between the head cells and the cuticle. When the gland matures, a nipple-like protrusion may form on the membrane from the pressure of accumulating resin. The bulbous glands are found scattered about the surfaces of the aboveground plant parts. [Pictured below.]
Capitate-Sessile: The second type of gland is larger (25 to 100 micrometers) and more numerous than the bulbous glands. They are called capitate, which means having a globular-shaped head. On immature plants, the heads lie flush, appearing not to have a stalk and are called capitate sessile. They have a stalk that is one cell high, although it may not be visible beneath the globular head. The head is composed of usually eight, but up to 16 cells, that form a convex rosette. These cells secrete cannabinoids and related compounds that accumulate between the rosette and its outer membrane. This gives it a spherical shape.
Capitate-Stalked: Cannabinoids are most abundant in the capitate-stalked glands, which consists of a tier of secretory disc cells subtending a large non-cellular secretory cavity. During flowering, the capitate glands that appear on the newly formed plant parts take on a third form. Some of the glands are raised to a height of 150 to 500 micrometres when their stalks elongate. These capitate-stalked glands appear during flowering and form their densest cover on the female flower bracts [specialized leaves that cover the seeds]. They are also highly concentrated on the small leaves that accompany the flowers. The male flowers have some stalked glands, but they are smaller and less concentrated than on the female. (2)
Cannabinoids
Cannabinoids are a group of chemical compounds that occur naturally in the cannabis plant, first discovered in the 1940s. When consumed by humans, the chemicals bind to CB1 and CB2 cannabinoid receptors in the brain and body, causing euphoria and other effects. The broader definition includes three general types: phytocannabinoids, which occur uniquely in the cannabis plant; endogenous cannabinoids, produced by the bodies of humans and other mammals, birds, fish, and reptiles; and synthetic cannabinoids, which are related compounds produced in laboratories. Cannabinoids present in the cannabis plant include THC, CBD, cannabinol (CBN), cannabichromene (CBC), cannabigerol (CBG), and tetrahydrocannabivarin (THCV).
Inside the TrichomeTHC and other cannabinoids are produced in only one place on the cannabis plant: inside the heads of the trichomes. How it happens: Organelles produced by the plant called Vacuoles – which contain phenols, a chemical compound similar to alcohol [pictured at right in blue], and another type of organelle called plastids – containing hydrocarbons called terpenes [red], make their way up the trichome stalk [green] and combine inside the secretory cavity into a fibrous mat [yellow]. This concentrated mat is hit by UV-B light waves, causing the creation of cannabinoids. Since all of the psychoactive ingredients are produced inside the trichome, these tiny resin hairs have long been sought after by hash and oil makers and can be separated from the plant and harvested in a variety of ways (3).
