It was the Vietnamese mainly I believe. I think the ones that were at it got busted or something eventually. I can't quite remember though, but we don't really get it anymore afaik thankfully. It's all the more reason to grow your own and ditch the dealer. Even if they're not adding glass or silicon, they will still be using harmful, carcinogenic fertilizers high in phosphorus, systemic toxic pesticides and carcinogenic growth stimulants like that awful Superbud that was around which caused loads of controversy. They don't care about your health so they'll use whatever they can to make a profit. This is why I will never buy from a dealer, it's just too risky. If I had a choice I would much rather put a little effort in and just grow my own 100% organic bud, preferrably outdoors any way. It's not exactly difficult and definitely doesn't have to cost that much. Having said that though 1 out of my 2 outdoor plots has proved to be unsecure, after I saw this twat standing right in the middle of it yesterday. Oh well, I still have one left which is okay.
