EVOLUTION, LAND RACES

Cannabis is one of the first plants cultivated by humans. I think classification is simplified by using 4 species. Cannabis ruderalis, C. indica, C. sativa and C. hemp.

C. ruderalis has origins in central Asia. Usually less than 2 ft tall, spindly, auto-flowering, maybe 1% THC and CBD. It could be the ancestor of the other species. Natural and human selection created land races adapted to different latitudes and climates.

C. indica, usually less than 4 ft tall, conical, dense foliage, compact buds, high THC, about 1% CBDs. C. indica ‘afghanica Clarke’ evolved for a long time at about 35 deg N, in a dry climate, slightly acid to slightly basic soils, often calcareous.

C. sativa, usually more than 4 ft tall, open branch and foliage structure, loose buds, high THC, about 1% CBDs. Adapted to sub-tropical latitudes, wetter climate, somewhat acid soils with lower nutrient concentration. More resistance to mould is a recessive trait.

C. hemp, usually very tall, little branching, loose buds, high CBD, about 1% THC. Many land races adapted to different climates and latitudes.

The chemical pathway for THC and CBD is either / or. The minor constituent is there because it’s chemical pathway is active at a very reduced rate.

New varieties/hybrids, almost anything is possible and the industry is a mess. A variety like ‘purple Kush’ from different seed companies or growers might be similar, but they usually have different chemistry and genetics.

More on how this relates to growing, soon.
Very Kool good info thank you

It was also learned that steelhead routinely breed with resident rainbows.
They are the same fish. I don't understand how this could have recently been learned when it's been known for a very long time. Maybe you're talking about some study on a specific stream that flows into a large lake?

The common understanding was that they were essentially cousins and not literally the same fish. The study was on the Hood River which flows into the Columbia River.

My brother teaches aquaculture at a large university. We have been fishing for trout since the 90s. He told me they were the same fish back then when he was in college. I can't list his sources of course.

I think it's been common knowledge that they are the same fish for quite some time. Steelhead are rainbows that leave the stream to live in some larger body of water for some time. They lose some of their markings while doing this. Several theories as to why but it looks like diet has a lot to do with it. The trout with high anxiety stay in the stream. Better to be a big fish in a small stream they must figure.

Same fish, always have been. We just call them Ocean going Trout in my state.
Yeah in the midwest they call something a perch in every area that isn't a perch. It might be a sunfish, drum, even shad. Depends which redneck you're talking too. They almost never mean a yellow perch.
Steelhead is one of those things. It came from the great lakes region. Some guys just feel more like a man when they say they caught a steelhead vs rainbow. Maybe they are just homophobes?...idk

Steelhead don't come from the Great Lakes. They're native to the Pacific Northwest and we're introduced to the Great Lakes the same as Chinook Salmon.

You're missing the point but you are correct . Rainbows come from the western side of the Rockies . Cutthroat trout would be their closest relative living in the streams that flow east from the rockies. Those are their natural ranges. We have stocked trout all over though. 1 trout stream in the state I live in. Brookies are the only natural species but they've stocked rainbows, cutthroats and brown trout. The browns are the black forest strain from Germany I think. Trout are everywhere there is good enough water quality at this point. Man has put them there. In Illinois we stock lots of small lakes with trout in the fall just for most to die in summer. It seems crazy.
In any case, I was saying the name steelhead. Not the fish steelhead which is just a rainbow trout in any part of the country that swam into bigger water and left the stream for awhile. They lose the pink stripe. There is no steelhead/ rainbow hybrid because they are in fact the same fish. Has been since rainbows and cutthroats shared a common ancestor and human beings were tree dwellers.
Trout are one of the best displays of evolution. I have a trout of the world map somewhere that includes salmon and artic char. It's fairly easy to look at a trout from one part of the world and see how closely related it is to one from somewhere else. They all have evolved from one fish that swam in a worldwide ocean eons ago. As the waters receded some got trapped. Over millenia they evolved to better suit their habitat that their ancestors were trapped in.

There are a lot of of different kinds of rainbows and cutthroats each native to their own particular region. My point, which you missed, is that you don't know what you're talking about.

The lots of different kinds of rainbows you are talking about are called strains. They haven't been separated as long as different species. No where near it . Like people in the south speak one way. People up north speak another. We are all still homo sapien.
Like I said my brother is the fish expert. I know my share. Evolution is my thing. I used both to demonstrate how you don't know shit. You just said I don't. Mine holds more weight.

Actually, I did a quick google and the Government of Alaska says they're the same species.

http://www.adfg.alaska.gov/index.cfm?adfg=steelhead.main

Would like to learn more. Personally they don't have either in my neck of the woods. Just brook and specs for the most part.

Rainbows are not native to the Rockies.
