Hi there, I was half way with a nice answer to you and I don´t think you are trying to understand or simplify.
“Weed is weed”, this is math, the first value is the second if the words are the same. If you think weed is not weed, then I think you don´t need to understand my point of view.
If you are confused and whiling to engage on a debate by simply disagree, Weed is weed, weed strains aren´t all the same. (Because the second part is unrelated with what I wrote)
Again: “a buzz is a buzz” not equal to “all buzzes are the same” in fact where did you got those ideas from one small sentence?
My friend, weed is weed and despite the strain, they all share their little character, sometimes they want something you don´t know what is, some times a phenotype will surprise you, you can advise someone to try strain A and he get a pheno completly different and scratch that strain just because he didn´t tried it as long as it should.
Just like a buzz is a buzz and that is when you smoke and feel the effects, tha is a buzz. Now knowing how differnt a strain can get, so the effects from your buzzes, I like to use a early croped bud during day to be more active and a later bud by the end of the day to drop down and relax, very different buzzes from the same plant.
Knowing this make you realize that strain exchange and smoke exchange can point you in the direction you seek faster than try and fail, but when you try, you stick to it, you will experience individual phenos, the main strain and early and mature crop, only then you will know if that strain A is what you want.
My point of view is that you can´t give someone the perfect grow formula that works for everybody, as you can´t choose a strain for others, you can Overgrow meaning growing plants as you grow as grower and human. and by improving yourselft you will notice that weed is weed, all strains share their buds, their stresses, their irregularities and singularities each seed carry on their dna, sometimes slightly different, othes very different.
When you realize this you will try the next phase, find the right plant, make it a mother and stretch that plant phenotype as long as you like or can.
Now don´t disagree over what I didn´t wrote, you usually disagree of the words placed, if you want details just ask and I will explain.
Have a nice one!
