When taking cuttings using organic super plugs, rockwool, or oasis foam, this simple and inexpensive tip will greatly enhance the root system of your cuttings and lead to a higher success rate. If you are using a standard nursery propagation flat and 72 compartment insert or one of our complete propagation kits to take your cuttings, place an air stone attached to an air pump in the bottom of the tray. Keep about 3/4 of an inch of water (and your favorite clone solution) in the tray, covering the air stone partially or completely, depending on the type of air stone that you choose. By bubbling air into the propagation water you will maintain an elevated level of oxygen in the water. Your cutting’s roots will develop more vigorously, and as an added benefit they will be able to stay in the tray a bit longer if need be.
