I have purchased from The Nature Farm twice now, both within the last 30-45 days or so. He is the breeder, selling his gear directly. Everything jayblaze said is right on. He has a huge following and continues to grow it, mostly through Instagram. Also a couple of video presentations on youtube, if you are interested in his farming techniques.
The listings don't always get the full description treatment, on his site. Like jay said, some are only up for hours before they sell out and are gone. Go look at a few other listings, and you will see that some do, others I assume he just hasn't taken the time to do so. The price is for one pack, of 12 regs. A freebie, full pack of 12 has been included with every order that I have placed, and seems to be the norm. In fact, the Windwalker that we are discussing, is one of the free packs I got. Not too shabby. Another was the professor jerry's og. Also, my last order, there was 13 seeds in each vial, not 12.
I purchased the 1969 Skunk#18 IBL and the Dumpster Skunk cross from him and have germed 4 from each pack, so far. All 8 seeds had sprouted tails in less than 24 hours, and were above ground in 3ish days from getting wet. Excellent germ rate and growth so far. That's as far as I have gotten.
As for payment, I placed each order and got an order number immediately. Sent money order across the country via snail mail, and received beans within 7-10 days. I had an issue with my first order, because I forgot to copy my order number. I reached out to him and he replied and got that number to me very promptly. Never had any weird vibes or bad dealings. Will definitely order again, and continue to see what his gear holds. Hope this helps.
