I've chatted with F_Dupp several times, he without a doubt brought something into his garden from the person/vendor he mentioned that is on strainly. F_Dupp runs a clean dialed in to the max grow, has been growing for many, many years. He trusted the wrong person with cuts. His yields went down dramatically from what they were a couple months before bringing the cuts in to his garden..the change in his yields after introducing the cuts is staggering. I'm talking about yields getting cut in half in a flash, some even more than half. Whats weird about his case is the trichome production was almost the same, almost looked pretty frosty but the buds basically stopped swelling and had absolutely no density, the looked brittle and looked like buds that would turn too dust simply breaking them up in your hands, most peaked and stopped flowering maturity by 6 weeks.
I saw a few members basically telling F_Dupp to take it somewhere else or stop posting about this, dude was just trying to give us fellow growers a heads up and most should heed the warning, if what happened to him happened to us it could have devastating effects on your grow room.
I don't think the issues popping up nowadays are some growers panic and people over exaggerating, I've seen really good and solid growers having issues with yields and vigor getting decimated within a few months when before their grow rooms where producing and chugging along fine. There's clearly HpLVD going around in cuts that are getting passed around and sold. When you think about it, never before has there been so many cuts being sold in traded in the states, its like a whole new little industry. With that said I think there others plant viroids popping up in cannabis that probably haven't really discussed much, there's another viroid that affects tobacco plants for example- TMV(tobacco mosaic virus). I think dark heart nursery figured out that the hop latent viroid was popping up more frequently in cannabis and people kind of just assumed it was a one size fits all for their problems when in fact its probably much more complex than that.
