Green House Seed Company’s reputation was built, in large part, on its carefully crated genetics, with the seed bank winning multiple cannabis cups over the years. So it is perplexing that such a company would now have so many complaints about the quality of its seeds. A couple of Green House’s original key breeders are now no longer with the company, which could certainly be a factor.
Green House Seed Selection and Quality Review
All of the seeds Green House Seed Company sells are its own strains. Some of these are completely unique to Green House, while others are the company’s own takes on popular favorites. This seed bank stocks close to 100 strains, including a few CBD-specific ones. Some (but not all) Green House strains are available to purchase by the seed. Green House takes care not to treat its seeds with harmful fungicides.
In recent years, a concerning number of buyers have experienced germination issues, including seeds failing to sprout, plants growing up weak, deformed, or hermaphrodite, or successfully-grown weed lacking the expected potency. Another factor that some buyers find off-putting is the colorful coating Green House covers its seeds in. The company states this is for the purpose of telling different strains apart, but it seems that most buyers do not care for this method.
For the most part, Green House Seed Company has a good reputation and high ratings on popular public forums. However, a large enough number of buyers with bad experiences have drawn concern about the consistency of Green House’s lauded genetics and reliability of its shipping methods.
