Yes, cynics are everywhere. Seems that this argument will just not die though. It also seems that seeds companies want you to think that seeds cannot be saved, (lets call it) virtually forever, in a freezer. So you buy more seeds from them. I have a pack of F13 beans that I got in a trade recently. DJ Short (you may have heard of him?) says on the package that his seeds can be frozen, but only once. I do not know why the 'only once'. But that is what he says. So there is some headway out there in the commercial Cannabis seed business that says that Cannabis seeds can be frozen.
The meaning of my statement above for all you skeptics out there is that studies in Japan have shown that frozen Cannabis seeds will likely last virtually forever if frozen around 0 deg. F. Humidity is less of a factor the lower the temperature, which is why I keep them that cold. Also most US freezers are set to 0 deg. F. I have grown many of my strains after being frozen for over 40 years now. And they have been thawed and re-frozen many times when I have moved up and down the west coast, moving them from freezer to freezer. As a result I have the original 1970s strains that I have posted here on 402mag. Believe it or not. I get up to 100% germination rates. Believe it or not. Several growers around the world are growing my frozen bean strains. Believe it or not. Cannabis seeds commonly tolerate freezing in the wild, and in multiple cycles as well. As in ditch weed in Nebraska, where it has been growing wild since WWII. It gets c-c-c-c-cold in Nebraska this time of year, no? Or in Kazakhstan where it has been growing wild for thousands of years. Or in Siberia, where Ruderalis is native and thrives. Funny how those Cannabis seeds naturally freeze in the fall and winter in multiple freeze-thaw cycles, and then they sprout in the spring. You would think they actually evolved to do just that! Cannabis also survived the last ice ages. Maybe not FOREVER, but what, it been 2.6 million years now in the latest ice age cycle? Close enough to forever in my book.
Its a paradigm that Cannabis seeds cannot be frozen. I read it in Ed's books and in magazines. Sad, but the science does not support the paradigm, and neither does my experience or my Cannabis seed collection. The science is referenced in the book published in 1977 called Marijuana Potency. Have a look. An example of my frozen seeds turning into plants is here, in this photo. This is a SW Mexican landrace grown from bag weed seeds that I got in 1976, froze in 1977 and grown in 2016. They were frozen for nearly 40 years and grown in 2016. It must be a miracle!
