EPA has is listed as a pesticide, though that _seems_ incorrect, it's a PGR/ Hormone. Never heard of it being used on cannabis, but I did find some foreign suppliers that elude to it's use for weed. If anyone has any firsthand experience with forchlorfenuron (aka CPPU, CT-30), I'd love to know as well. May order some for testing, but need to find it in small enough quantity - i.e. don't need a 50lb drum of it.
