I know my birxperiment is no where near intense as yours, but for the most part mine also seem to have smaller trichomes, but mine are less numerous on the leaves, but packed in on the buds.
My WW x Querkle cross is REALLY good from the 7 wk test buds picked last week. It just doesn't seem to last as long, about an hour and a half, as some of the other strains, (2-3 hrs). Although it will get another week or two to grow. I think she may surpass her mothers intensity. You can feel the high between your ears for about 20 minutes then it seems like it melts down through your body.
Well, I don't know how I feel about PGR's at this time. I'm not using them at present, other than natural PGR's that are DEFINITELY designed to be used on food crops.
I do know how I feel about agenda driven scare tactics, especially when dished out by government cubicle dwelling drones. I'm not convinced PGR's are evil, based on the research. However, I'm also not completely convinced they're safe.....so I'm not using them lately.
I would LOVe to use some Bushmaster on the Columbian...but I'll wait till I know more.
