Made some beautiful Sweet Tooth seeds 7 or 8 years ago and have kept them in a fridge with q-tip ends to absorb any moisture in small baggies. (kept inside another dark container that is inside a thick freezer proof plastic baggie) They were dried for about a week or so at room temp after coming out of buds that dried for a week at room temps of like 75f. If I germinate any of them they are 90-100% still and ready to go no problem. This is because they have been kept cold, dark, and dry.
Also, letting the seeds fully mature on the plant is crucial to the resulting seed health, pollinate very early in flowering when you have ample white hairs and do not wait until the end of the bud cycle because the plant will be deficient in many aspects by the tiime it has grown huge flowers. Don't expect to get very much smoke if you do a full seed run. Seeds grown under very bright full spectrum light (Blue and Red) with good nutrients and great plant health will give you the best long term germ ratios and quality seeds. Co2 supplementation is highly advised for seed making as well since it's a crucial building block for the seed creation & overall development.
Avoid exotic bloom boosters or too many excess supplements when making your seeds and give the plants a very balanced N/P/K ratio without overdoing any one element or you may end up with seeds that have very thick skin with problems germinating out of or shedding it's shell. This problem is from p/k overload during the seed creation & growth. A 1/1/1 ratio of General Hydroponics Flora series works great for making seeds that are very healthy and can germinate easily, a little extra of the bloom is fine but don't use lucas formula for making seeds. They need plenty of nitrogen. You are trying to replicate conditions that might be found in nature so don't fertilize the plants as if you were growing big monster seedless buds, you are growing seeds and the needs are different. Follow these simple basic steps and you cannot go wrong, properly grown and stored cannabis seeds can last you ten to fifteen years easily. People have grown seeds out that are over 20 years old, happens all the time! Love & light to you all!
