I don't know all of them that are associated with each other but you are kinda right. They are separate companies and not owned by Neptune but I think Neptune has a deal with several banks where they act like a warehouse and drop ship packs for other seedbanks once the order is placed. I think platinum, nucleus, supreme, and healthy made seeds (just recently) are just a few that I think do this along with a few others. I know I have placed several orders through seedbanks that ship from the same location in California, even with one seedbank that is located in Oklahoma, yet the packs ship from the same city in California.Does one company own a majority of the seedbanks in the US? Just noticed that neptune, platinum, westcoast, chronic all seam the same?
