I believe the only reason for not allowing open trading is profit. Seed vendors that host sites are motivated not by altruism but to sell more. I get it.However, it is a monumentally simple to ask a member to engage in a conversation via another website, e-mail, ect to ask any question that is on your mind. I have no experience and no logical reason to believe that growers will ever stop giving other growers cuts or seeds, but I also believe that if the product & price are better than the competition a seed seller should have no trouble selling enough seeds. Truthfully, the success of most seed vendors is the selection of seeds they sell, or if they buy enough of the right seeds, not whether site users are trading f2s... Wanna sell more seeds? lmao, then keep more gear like Exotic Genetix , or maybe 303 seeds.... just buy more of the in demand seeds so ya dont run out as fast. ;) peace...
