Yes, in the books by George Van Patten (Cervantes has come out of the closet on his videos about his real name now), Ed Rosenthal and several others, they say that freezing seeds is detrimental. That is still the paradigm for whatever reason. However those claims are not based on any empirical evidence or experiments, or the likes of my results. Or the fact that Cannabis grows wild in many areas in the world where they get hard frost in winter months. Like say, Nebraska or Kazakhstan. As for refrigerator temps, that is a good way to store them ~if~ they are kept very dry. No need for liquid nitrogen in my experience. 0 deg F. freezers have done just fine (both defrost and no defrost).
As for this thread, many here and on other sites think I am making all of this stuff up. Both the fact that I have these seeds (of which are now only 1/4 of my collection) and that they can be frozen for long term viability. Its both amusing and annoying. Of course, the seed companies do not want people to know that seeds can be stored safely and easilly for long periods of time. So I guess its an economic thing and we are a thorn in their side. Never mind the likes of us having the old genetics that are otherwise nearly extinct now. I get a lot of requests from seed companies for my genetics. Imagine that?
Also the other paradigm prevails about Amsterdam genetics being oh so much better from Arjan & Co. I get that line all the time. Even my oldest brother who had Nevil's seed catalogs going all the way back in the early 1980s. He still insists that Amsterdam genetics are the best of the best. He sent me an email a few months ago saying that. Then as now, I was growing my landrace strains. In the early 1980s I could not fathom paying $5 for a single seed, plus shipping. Seeds were free in bag weed so I thought it was insane. Also Nevil's strains were all from local strains available as bag weed in Northern California at that time. Skunk, so called Haze (any number of available Mexican or Colombian strains), California Orange, etc. I also had seeds from local Big Sur grows, Thai sticks, Hawaiian and African weed. More recently I have grown landrace and heirloom seeds from places like Lebanon, South Africa, India and North Africa. Yes many are wild "bushweed" and landraces and some of them are hay. They are not indica or OG hybrids which account for 80% of the local stuff sold here. But I was and still am not after couch lock and brain freeze weed. I like high terpene strains. I like high THCv weed. I also like high CBC weed. And Kona Gold. Whatever is in Kona Gold, I like that. Not sure what it is yet. I traded for a cache of Kona Gold seeds on the Big Island recently. Old school. The weed I first smoked back in the day and still like to smoke. Sativas! Why the world has gone over to the dark side of OG Kush I do not know.
