I have seeds that an old grower gave me to germinate because he wants to grow his strains again since its legal now. These seeds are from the 70s! I’m having trouble sprouting them because they are soo old. I have a bunch so i can keep trying. What’s the best way to sprout these old beans?
I followed ilgm seed sprouting instructions with no luck.
Give em a rub with a nail file or sandpaper. Long soak with hydrogen peroxide added to water.
It’s totally possible so don’t give up, however depending on what conditions they where kept in, 50 years is a long time.
If i had a bunch I’d try a bunch on a cup of water and see what pops.
Rolling a peice of sandpaper up liie you going snort a line with it and then drop some seeds inside holding the ends closed with 2 fingers and give them a shake, this should help scuff them up a little, soak in water with a little bit of h2o2 and cross your fingers.
Clone whatever you get luck with if ya need alot of plants .
Soaking old cannabis seeds in kelp extract can indeed boost germination success. Many growers follow this practice by immersing seeds in a solution of kelp and water for approximately 24 hours before planting. The benefits of this method include:
To try this method, you can soak your cannabis seeds in diluted kelp extract before planting. Happy gardening!

I had good results etching the shell and using a drip of rooting gel dissolved into the water with some almost 30 year old seeds.

If your successful take some clones
Personally I wouldnt waste my time on a seed from the 70s. You’ll have to be on the look out for males or youll really tick off the fem growers within a 10 m radius. Ruderalis strains are sold feminized nowadays.
