I have been dealing with Dr. Greenthumb Seeds in Canada for something like 15 years and most of my keeper plants like OG Kush, Sour Diesel, Chemdawg etc.,have come from there. My mates and neighbours always ask where I get my genetics and I always tell them Dr. Greenthumb in Canada. Well it seems there is another edjit who is trading on Greenthumb Seeds Canada good name and selling seeds thourough Humbolt Seeds Organization, who you'd think would be out of California but in fact out of the U.K....but that's another story. This guy in Colorado who calls himself variously Dr. GreenThumb, Dr. Green Thumb and now just Dr. Greenthumb is confusing the community into thinking he is the real Dr. Greenthumb. I only learned this when my mates asked why they weren't getting the same kind of results I was. Their plants yielded less, were less potent, had lower germination rates and hermies...I've never had a single hermie plant from the real Dr. Greenthumb. The fake Dr. Greenthumb and HSO seeds offerings cost less but in my opinion and that of others, they aren't as good. It's up to the consumer to decide but I just thought the community should know.
