Say I bought some seeds, how long would these be 'valid' for? Do seeds have an expiry date? Stupid questions I know, but if I bought a pack of 10 seeds, I'm not going to grow all 10 plants, I'll probably try 2 at a time, meaning the other seeds are going to be sitting in a bag for god knows how long, especially the last few. I definitely want to start growing in the future for my own and friends use.
I've seen people on here that have grown seeds that are 10 years old mate, use the germinating method of your choice to make sure they are viable before puttin them into soil and under lights.
