Good weed is subjective. The grower also lets it go another week or two
I did some testing a while back. Actually testing on paper. The highs change somewhat subjectively depending on harvest but on paper not much changes besides maybe plant weight. Selecting for a particular type of high just might be the harvest window your going for. Or maybe most Thais and Africans are just really strong fucking dope. If you want something uplifting and spacey you may want some Mexicans.
What a lurker. It took the haze to bring you out of retirement. Hahahahaha
