So I am a newer grower. Very first seeds I ever bought were from Seedsman. First 6 seeds I ordered were Purple Lemonade Auto’s Feminized, which came with 3 OG Kush Photo seeds. All 9 of those seeds germinated properly and produced really good yields. Since I had a great experience I recently ordered 6 West Coast OG Auto’s which came with 3 White Widow Autos. Ever order I was given an estimated delivery date, and they always show up early. I will be a lifetime customer.
