first off with the dunking you can take a sterile pitcher and fill it with distilled water and dunk them in it then roll them in dry vermiculite and place them on the trays which you will have lined with clay pellets that you can find in a pet store or a hydroponics store. remember to wet the pellets or your fruiting chamber wont have enough moisture.
