Thanks MJ.

Up to 4 days is normal, it all depends on the quality of the beans.

I soaked the seeds in a cup of water for 24 hours or until I saw the root, whichever comes first. This way the seeds are immersed in water which penetrates the shell quickly and stimulates the root to pop out. Some people add a few drops of Superthrive to the water.

Afterwards you can just plant it 1/4"-1/2" deep in soil or rockwool like I did. I used a small spoon to fish them out of the cup, just be careful with the root.
