I have used the NWTF for seeds many times over the past 10-15+ yrs now
normally once you get on the buyers side of things, IF you stay in contact with the seed guy, you buy from, they will let you know what seeds are available a few weeks before they GO get them, as they mostly DON"T know too far in advance, as it all comes down to what they Get and then its like a first come first serve deal
I have had yrs when they had a tractor trailer of seeds at ONE location, and you came and you got to buy from what was on truck for sale, and prices can vary
I have also had times when I had to PRE order and I was then HELD to buy what I asked for.
and yes, you must sign an agreement that states seeds will NOT be used to harvest, and for wild life only!
I also, recommend adding some inoculate to the seed at planting time, its cheap and cannot HURT ONLY help
as these are always 1-2 yr old seeds your getting
That said, I have never NOT had them grow and some SUPER crops some yrs, I know one yrs 2010 I think, the main field I rent out to a large farmer, , I had higher yields on my corn, larger more kernels and more ears per stalk than his
he was actually asking me what seeds I used LOL
deer ate them down to nothing by about Mid feb however
but its a awesome program for food plotters , all the more so if your on a budget!
