Officially, there is only one species of marijuana: cannabis sativa. The original cannabis sativa often grows to 6' or more in height and takes some months to come to maturity. Though it can be forced to maturity more quickly under controlled conditions, it will still attain a substantial height or length of stem. It can be cultivated for higher THC content, or grown for fiber or hemp, with virtually no THC at all. Starting in the 60s and proceeding to the present day, serious marijuana growers have sought to breed a type of cannabis that would have a smaller habit and quicker maturation, and be better suited to indoor cultivation. And of course they also worked to increase potency. At some point, C. sativa was crossed with a plant called ruderalis, a cannabis cousin with virtually no THC content that grows on the steppes of Russia and in Hungary. Ruderalis is a small, upright bushy plant that tolerates cooler temperatures, and crossing c. sativba with it has yielded a distinctly different type of marijuana. While botanists and mainstream science fail to recognize the difference, cannabis indica is regarded as a separate strain by marijuana growers and informed pot-heads. The sativa types, with their longer growing season and very tall form, produce marijuana that is known for its light "head" high. Indica types grow short and fast, producing resinous, sticky, stinky buds that yield a heavy "body" high. Although illegal in most countries, there are many sites on the net that offer marijuana seed for sale. The naming and information on many of the strains that are offered makes it clear there really are a number of different "types" of marijuana, varying not only THC content, growing conditions, and habit, but also in the basic nature of the "high" they produce . There are also many sites on line to read about continuing breeding efforts. JohnDoe: Sativa and ruderalis are certainly separate species. Indica is not yet a part of the official taxonomy. Sativa is specifically an equatorial plant (rather than tropical) and ruderalis does come from the steppes. Indica is the result of specialized breeding of the two other species and is more tolerant of a range of growing environments.

I'm pretty sure they do. there are tons of different kinds of weed: dro (grown in water) chronic and haze fall in the same catagorie, im pretty sure they're grown in coca plants, giving them a slight cocaine effect. there are also many types of weed that differ slightly because of the environment they grow in. regular pot, as i hope you're aware, causes a dreamlike feeling in its user. it can also make the user incredibly hungry (munchies :)). sometimes it can cause a feeling of panic or dread (which i hate). dro has a much more heavy and drowsy effect. deffinatly the most altering of all of them, it makes the user feel underwater and weighted down. things seem slower. the quality of this can usually be determined by its redness (the redder the better). some of the best weed philosophies are done on dro. then there's the chronic/haze catigory, these usually give a feeling of being uplifted. it usually causes increased energy (not to mention the biggest case of the munchies). another, stonger member of this catagory is diesel (sour diesel and silver diesel)

As an experienced grower in soil and hydroponics, both indoors and out... I'll give you the correct answer for this. First off, yes. Different 'species' give different effects. Sativa gives a trippy, in your head high. Indica gives you a couchlock, munchies type high. But it goes much further then that. Much further. Due to technological advances in agriculture and horticulture, not to mention genetics and techniques, marijuana is now slightly more powerful then before. Not only is technology better, knowledge itself is allowing breeders to design strains. In countries like Holland where marijuana laws aren't as harsh, breeders create thousands of plants to find the best candidate. They do this again and select another fine candidate. Then they cross the two strains. The result is a hybrid with the genes of superior parents. After stabilization, this newly created strain will probably have the effects they desired. This is somewhat along the lines of designer drugs. They are designing plants for specific purposes. I have a vast knowlage of strains and their effects, so I will give you some examples. G13 - Rumour has it that this strain was smuggled out of an university program which studied marijuana. Apparently it had been genetically engineered to have a higher THC content. This may or may not be true, but it's potency is unmatchable to this day. Chemo - Designed to provide the best relief to medical marijuana users. Very strong. B.C. Skunk - Developed by biker gangs in Canada to be potent and yield well. Usually comes from B.C. into the states. This is why the 8 billion/year marijuana market in BC is bigger then their 7billion/year lumber industry, famous for the giant redwoods! Strains are usually designed for potency, colour, bag appeal, yield, smell, taste, size, and growing time. This information is correct.

Yes, Different types do have different effects. As "Weedman" said, most marijuana makes you feel like you are in a dream, causes panic Depending on how much you smoked. The first time you get really stoned it hits you hard, and you definitely need a good friend with you. Some kinds of marijuana can have effects like Going blind, deaf, and hallucinations. Blindness lasts for about 20seconds, then deaf for about 10, then your hearing is muffled. It is best to lay down, eat and drink some water. Hydro makes you feel like you are weighed down, and you see yourself as moving way slower than you actually are. It feels weird to look in a mirror because then you see that you are actually moving at a normal speed. But effects differ by every person. Some better, some worse. You learn more by smoking more.

CA has bud called train wreck, it is the kind, purple haired INDICA, is good and strong pop corn bud is hard to find sensimilla is kick ass chronic is well just right on skunk bud is ,for all of us midwesterners

Yes Cannabis has three purported species: • Cannabis sativa The high is usually more cerebral and more of a head high. Not much of a stoney feeling, also it really doesn't make you tired. The high is very clear. • Cannabis indica The high will be more sedative. As others have described it as "couch lock." Many of the strong indica strains have been well known to relieve pain. • Cannabis ruderalis These plants have been said to be low in THC and CBD(active ingredients) because they escaped cultivation and adapted to their surroundings. This species alone has little use as a drug but some of its traits can be taken advantage of through crossbreeding. ­ ¤ ¤ Many strains commonly smoked today are crossbred variations of these three. Seed companies will usually list the percentage of indica vs. sativa.

yea they have different effect some leave u hugury, while others have you restless. one thime i was so high that i lost my motor skills temporarily. it makes u wanna say whats really on your mind. im good with it.

what the hell are u talking about grown in coca plants that rediculous pot is pot sativa indica are the different types and then u got cross breeds half n half or whatever growin cocain plants is the stupidist thing i have ever heard.and going blind and deaf is just as rediculous,maybe muffled hearing but know what ur talking about before u put it down in words read a little marijuana is harmlessto the human body especialy if eatin. weed man you have no idea what ur talking about hydro is just a way of growing it its not a breed dont call urself weedman when u know nothing about weed.
