I started sending this out with all the seeds I gift people. It doesn't make non viable seeds viable, but for older dried seeds it really helps. Once they hydrate for 48 hours I can usually crack them between my fingers, I rarely have to use the hash press.
"I use calcium in my feeds, LOTS of calcium. In addition to growingstronger, healthier plants, it can also make the seeds I make veryhard to germinate using standard methods due to very thick, hardshells.
Thisis the protocol I use with great success. It is a little moreinvolved but gives me great germination rates if you follow thesesteps.
STEP1– cut a 100 grit sheet of sandpaper to fit a pill bottle. Placeseeds inside and agitate in a swirling motion for 10-15 minutes. You may have to take a break and let your wrist recover from time totime.
STEP2– Place the seeds in a sanitized container with 2 ml of 3% hydrogenperoxide and 3 ounces of tap water. Soak for 4 hours.
STEP3– Pour off the water/peroxide mix and replace with tap water.
STEP4– Check seeds every 12 hours and plant any seed that shows anexposed taproot.
STEP5– Change the water if it becomes cloudy at all.
STEP6– If no tap roots are showing after 48 hours of soaking, manuallycrack the seed. Often this can be done with just finger pressure,but if that is not possible, I employ a T-handle hash press.
I unscrew the bottom and load the seed. Then with the ram loweredalmost all the way, I gently screw the bottom back on very slowly.
Thismay take some practice to get right, but if you go slowly, you canfeel the seed cover “pop” and crack. At this point I usuallyreturn the seed to the water for 12-24 hours and then plant."
