Congrats on your order! The germ length sounds a little long though at 4 days. Do you mind my asking what your technique was?
I use a cup of warm water and I put the seeds in there and keep the cup in a dark place, if you can find someplace warm that's even better. I leave them overnight and the next morning I check to see if any sank to the bottom, those will be ready. The ones that are still floating, I push them down and if they sink, they're ready.
Any that remain floating I put in a wet paper towel for another night. With this method my seeds always germed in <2 days. I think having to wait 4 days is torture dude!
