One particular heinous method was the use of Colchicene { spell?}
Used on the budding branches, it created the first "super weed".
Highly toxic! DO NOT USE! Then there was PCP, again, too toxic!
Straight up lovingly grown herb as it is meant to be can not be beat.
If you grow crap, dump it and start again. Anyone can get it right.
The guvm'nt will be putting out its own stuff, and I think it will be tainted.
Know your supplier, and trust only those that use.
