Are reviews something good to go on when buying seeds online? whether about the company or the reviews they have on the seeds?
In today's online world.. its honestly hard to put trust into either. There are entire firms built around website reviews... who remove, post and analyze reviews to get the best rating for the hiring company.
With genetics, unless you are going breeder direct, In my opinion, you never really know what you are getting, and even with that being said, some breeders are scammers themselves.
Its best to go directly to breeders who are very well known for their detail and quality, who can trace seed genetics and lineage back to where it came from and who truly have a name, not by their own marketing, but by others vouching for their legitimacy. There are a few out there, but unfortunately it would be against forum rules to post them, but they are out there with some clever CSI work.
Best suggestion is to network with other growers/breeders who you admire or who have genetics that have proven themselves in actual real world grow situations and either work out deals with them, or find out where they sourced their genetics. Seek out the actual breeder who created certain strains is really the best route. Most are surprisingly open to helping fellow growers out...
