I store it in a couple large containers at the back of my herb cabinet..salvia will last for a long time this way...I dont think it really degrades much at all in a dakr place away from light. Ive been growing it and storing it this way for years.
That harvest was not all at once haha..I could have a harvest like that if I wanted to but I personally dont harvest my plants for leaf really ever unless taking cuttings..I just let them grow till they are ready for cutting. You have to take a couple leaves from the bottom of the cutting where its gunna root so thats the only time I harvest leaf. They also drop some leaf here and there all the time on the floor or my deck as they grow so I just take them too..even the dried up dead leaves they sometimes drop whiling growing indoors are potent.
Right now I have about 20 plants maybe more..but they are between like 10 pots. Some are little baby cuttings others are larger more established. All origionating from the same one mother plant I got like 6 years ago...I often just stick a couple cuttings into one pot.
My plants just veg slowly indoors now till about end of april start of may, when they go back outside..then they grow like crazy again..then another harvest over the summer like that..maybe more even.
And yeah..I quid it every month or 2..have not smoked in years really but Im gunna make some extract with that powdered leaf in the container..thats 40g of leaf in there so I might make 4g of 10x..or just extract crystals..not sure. Been a long long time sinse I smoked salvia extract. Most often I quid it with a bit of ayahuasca, or some sort of low dose tryptamine. Sometimes I quid it alone, but 2-3 leaves on top of some ayahuasca is one of the best trips.
Long live the unwoke.
